Press the Power buttonagain for two seconds to turn off thereceivers. The backlight on the LCD willdisplay OFF indicating the receiversare off. At power-off the 4W-1KU QUADreceivers will store the last settings enteredand re-display them at power-on. It can bereprogrammed to any new Group/Channel,or Volume level. The default factory settingis Group 00 (Receiver 1) and 03 (Receiver 2),
  • 06 (Receiver 3) and 09 (Receiver 4), Channel00 and Volume 63 are same for all receivers.The(Up) or (Down) Buttons (7) are activewhile in the Set mode, or can be used tochange Volume level (11) at anytime.When the Set Button (6) is repeatedlypressed the lCD Display (8) menus will cyclein the following order:MAIN MENU>CHANNEL>VOLUME>GROUP>MAIN MENU(repeats)During manual programming, the selectedfunction will flash for five seconds or pressthe Set button to confirm the selection andthe display will return to the main menu.The aUTO-SCan / aSC (IR Sync) Button (2)has two functions:Long press (hold ~2 seconds) for AUTO-SCAN for finding a clear channel within84W-1KU Receiverthe frequency band (with all TXs turned offat this time). Clockwise running segmentson the LCD display show the scanningis in progress which normally takes tenseconds. When it finds an interferencefreechannel,itwilldisplayandstorethat
  • channel for use. Then ASC IR Sync theTX as described below.Short press (~ 1 second) to transfer theselected frequency information fromthe receiver to the transmitter for easysynchronization prior the transmitter canbe used. When short pressing the ASCIR Sync button while the main menu isdisplayed, the IR leD (4) will light up redand stay for about three seconds. Thisindicates IR transmission is in progressand IR data is transferring during thisperiod. A transmitter should be usedat this time to receive data from thereceiver (see IR Sync Programming inProgramming sections of HT-1KU andBT-1KU transmitter sections). Uponsuccessful data transferred (usually inabout three seconds) the IR LED stopsand the transmitters backlight will lightup and the transmitter will transmit aradio signal on the same channel as thereceiver. The Signal Strength and DiversityIndicators on the receivers LCD displaywill then light up, indicating that the IR linkis completed. If manual channel selectionis preferred, skip this selection.Note: If you are using multiple transmitters atthe same location, set up the first transmitterand leave it ON and keep it 3 ft. away fromthe receivers. Then start AUTO-SCAN on thesecond receiver. This avoids duplicate selectionof the same channel as already selected for thefirst receiver. Using these procedures for theremaining receivers to be used.If you are not satisfied with a channel afterscanning, repeat anytime for locating anotherfree channel.Selecting the 4W-1KU QUaD Receiver
  • Volume level / Group / ChannelThis section will also aid in finding desiredchannel(s) of operation when setting upyour system(s).Press the Set Button (6) three times tocheck the current Volume levels (12) setting.To change the Volume Levels, press the(Up) or (Down) Buttons (7) anytime forsingle stepping, or hold the Up/Down buttoncontinuously for faster level selection.Select 1 of 63 (soft to loud sound) levelsfrom the Volume menu and advance to exitSetup Mode by pressing the Set Buttonone more time. Selecting 0 should mutethe receiver and no output for the Line Outonly. The XLR out is unaffected.Choose the 4W-1KU QUAD operatingfrequency by selecting one of ten Groups(9) and one of 100 Channels (10) that aredetermined to be desirable open channels.Press the Set button to enter the Groupsetup mode and the Group icon will flash,then press the Up/Down button once forsingle stepping through the groups, or holdcontinuously for faster group selection.Select 1 of 10 groups available from theGroup menu and then press the Set buttonagain to Channel Setup Mode and theChannel icon will flash, or press the Setbutton three times to skip changing theChannel or Volume. Within the ChannelSetup menu, press the Up/Down buttononce for single stepping through thechannels, or hold continuously for fasterchannel selection. Select 1 of 100 channelsavailable from the Channel menu or pressthe Set button twice to skip Volume Levelsetting and exit to main menu. Duringmanual programming, the selected functionwill flash for five seconds or press the Setbutton to confirm the selection and the
  • display will return to the main menu. Fordetail how to IR Sync the TX, see IR SyncProgramming in Programming sections ofHT-1KU and BT-1KU transmitter sections.Rack-mounting the ReceiverThe Nady 4W-1KU QUAD receiver wirelesssystem has built-In Rack ears (13). Use thesupplied screws to install the receiver ontothe rack.Note: Do not mount the receiver on a rack directlyabove an amplifier or other source of high heat.This could degrade the performance of the4W-1KU QUAD. Always ensure adequate airflowand heat dissipation in any rack configuration.Installing antennasInstall antennas by connecting the twoantennas (21) included with your systemonto the two RF Connectors (14/19) locatedon the back of the 4W-1KU QUAD receiver.The two antennas must be installed in orderfor the diversity circuit to work properly.The optimal positions of the antennas are45 from the receiver and 90 from eachother. For maximum range, it is always bestto maintain a line-of-sight (no obstructions)between the receiver antennas and thetransmitter at all times whenever possible.To install optional antenna extension Cables(13a), insert one end of each cable intoa rack ear hole and secure using theremovable nut. Clip the other end of thecable to an RF Connector (14/19) on the backof the unit. Connect the two antennas tothe front of the system.Powering the ReceiversTo power the receivers, plug the providedAC/DC Power Supply (20) adapter into the DCInput Jack (18) on the back of the receivers,then plug the adapter into an AC outlet.Note: Any 16-18VDC source with minimum800~1000mA capacity can also be used.
  • Once the receiver is connected to thepower source, press the Power Button (1) fortwo seconds. The lCD Displays (8) will light(showing Group, Channel, RF Level Meter,and Output Volume). The Diversity a/B (2) andthe aF PeaK leD (3) are off at this time andwill display when the transmitter is on andthe audio is transmitted. To turn off, pressthe Power button for two seconds. The LCDwill display OFF then the backlight willturn off indicating the receivers are off.Connect either the Unbalanced audioOut (17) or each XlR Balanced Mic Outs (15) toyour mixing board, effect, or amplifier inputs(See Connecting the Audio Outputs section).9adjusting the SquelchIn normal operation, each 4W-1KUQUAD receivers Mute Control (16) worksindependently and should be adjustedclockwise (CW) to the minimum RF squelchsetting at which the RF level Meter (12)and one of the LED Diversity a/B Indicators(2) will remain on while your transmitteris in normal use, up to the maximumoperating range anticipated in use for yourapplication. However, in areas of high RFactivity, the MUTE control may need tobe adjusted counterclockwise (CCW). Ifthe transmitter is off, the receiver signaland the RF Signal Meter (12) and one of theLED Diversity A/B Indicators is flickeringor stay on continuously, the MUTE levelshould be adjusted higher level CCW(counterclockwise for less mute sensitivitylevel) to stop the flickering. Be careful notto adjust too high CCW setting as this mayreduce the operating range to below whatis needed. A range walk test will help inselecting the proper level. If the range isnot critical, note that a counterclockwise
  • (maximum mute) setting will also yielda quieter mute function, which might bedesired in certain applications. The MUTElevel is factory preset at clockwise (CW) formaximum sensitivity and operating range(i.e. clockwise (CW) for minimum squelchlevel maximum usable range).audio level and Peak leD IndicatorThe 4W-1KU QUAD receiver has an aF PeakleD (3) display for each receiver and eachworks independently per channel. The AF PeakLED occasional flickering green on normal orloud inputs to the transmitter is normal. If theAF Peak LED lights green continuously, youmight overload the system. Decrease theaudio level input to the transmitter or overloaddistortion sound may result.Connecting the audio OutputsThe 4W-1KU QUAD receiver has oneUnbalanced audio Out (17) (adjustable Linelevel) SUM audio output and four Balanced10Mic Out (15) (fixed level) XLR jacks and eachoutput works independently per receiver.The Unbalanced Audio Out is controlledby(Up) or (Down) Buttons (7) for volumecontrol and the receiver Sum Volume Meter(11) will indicate the level selected. Forunbalanced output, plug an mono (Tip/Sleeve) audio cable into the Unbalancedaudio Out (17) and plug the other end intoyour mixing board or amplifier. Whenusing the BT-1KU instrument transmittersystem, connect the Unbalanced Audio Outdirectly to your instrument amp or preamp.At maximum receiver volume setting, asindicated by the Sum Volume Level display,the system output is approximately +4dBhigher than a direct cord-to-amp connection.Note that all receivers output will be mixed
  • together as per the individual receiversvolume settings as selected by the up/down volume controls. If separate signalsare required for each instrument thenthe Balanced Mic Out sockets must beused. However, they are not line level oradjustable. The SUM out is best utilized forswitching between separate transmittersduring performance with only one audiosignal at a time fed to the instrumentamplifier. For balanced output, plug an audiocable with an XLR connector into eachreceiver and plug the other end into yourmixing board or amplifier inputs accordingly.Note: As when making any connection, make surethe amplifier or mixing board volume is at theminimum level before plugging in the receiver toavoid possible sound system damage.Your 4W-1KU QUAD receiver is nowoperational and ready to use. Once youhave completed the above steps, proceedto the following instructions for the HT-1KUHandheld or BT-1KU Instrument transmitter.Note: Only one transmitter can be used with onereceiver. It is not possible to use two transmitterson the same frequency and mix the output ofthese transmitters into one wireless receiver.However, as this is a four receiver unit, fourtransmitters on separate frequencies can beutilized, one with each receiver.HT-1KU HandheldMicrophone TransmitterButtons FunctionThe RF Power level Switch (27) is used toselect Hi/Low power transmission.Each time the Set Button (26) is pressed, theLCD menu will cycle in the following order:MAIN MENU>CHANNEL>
  • VOLUME>GROUP>MAIN MENU(repeats)The(Up) or (Down) Buttons (25) work inthe set mode only. They can be used tochange any Group/Channel as selected(if not using IR Sync from receiver).They can also be used to select the desiredInput audio level VOL setting. Or they canbe used to turn on the LCD display.During manual programming, the selectedfunction will flash for five seconds, or pressthe Set button to confirm the selection andthe display will return to the main menu.Setting up the TransmitterThe HT-1KU requires two AA size batteriesto operate. To install the batteries ontothe battery compartment, unscrew theBattery Compartment Cover (22) by turningcounterclockwise until loose and slide downthe cover, exposing the Battery Compartment(35). Insert two fresh aa batteries (36)according to the correct polarity as indicatedon the transmitter body. Screw the batterycover back onto the microphone, makingsure it is securely tightened. Fresh alkalinebatteries can provide up to 8-10 hours ofoperation, but in order to ensure optimalperformance it is recommended that thebatteries be replaced after 6-8 hours ofuse or as indicated to be necessary bythe flashing Battery BaTT Meter Icon (33).Powering the Transmitter On/OffTo turn on the transmitter, slide the PowerOn/Off Switch (28) to the ON position. TheLCD backlight will light up, indicating the unit
  • is now on. After ten seconds the backlightwill automatically turn off to conserve batterylife. The Group (30), Channel (31), Input Volumelevel (32), and Battery Meter (33) indicator iconsstay on for normal operation.As many of the LCD battery meter levelsshould stay lit as possible, as they indicateusable battery strength. As the batteriesweaken, fewer of the level indicators willstay lit until only one bar shows, which willthen flash to warn that the batteries are nowtoo low and should be replaced as soon aspossible with fresh ones.To preserve battery life, turn the transmitter offwhen not in use. To turn the transmitter off,slide the power on/off switch to the OFFposition. The LCD will display OFF, no LCDor backlight is lit up and the unit will be off.At Power Off the transmitter will store the lastsettings entered and re-display them at thenext power on where it can be reprogrammedto any new Group/Channel or Volume levelat the first time of use or anytime later.The factory default setting for Volume -10dBis same for all transmitters. These settings areoptimal for most applications.Programming the HT-1KUto the Selected ChannelThe transmitter can be programmed to thesame frequency as selected for the receiver,either via automatic synchronization usingthe IR Sync function or manually on thetransmitter itself.IR Sync Programming:Use the wireless IR leD Receptor Sensor (34)to download pre-programmed channelsfrom the receiver. Start programming byholding the IR Receptor Sensor/Window11about 6-12 from the receiver to be used.On the receiver, when short pressing the
  • aSC IR Sync Button (5), while the main menuis displayed, the IR Infrared leD (4) will lightup red and stay for about three seconds.This indicates IR transmission is in progressand IR data is transferring during this period.Upon successful data transfer (usually inabout three seconds) the IR LED stops andthe transmitters backlight will light up andthe transmitter will transmit a radio signalon the same channel as the receiver. TheSignal Strength and Diversity Indicators onthe receivers LCD display will then lightup, indicating that the IR link is completed.Note, if procedure is not done correctlyduring the three seconds of active datatransfer, the receiver and the transmitterdo not link and transmitters previousprogrammed channel remains unchanged.Note: The IR link is infrared light and thus worksbest when this data transfer is accomplished in alight-shielded or darker environment. It may notbe successful in a brightly lit area. If the transferfails, repeat the procedure in a darker locationor somehow shield the link from outside light tosuccessfully program the transmitter with thepre-programmed group and channel info fromthe receiver.Manual Programming (GRP/CH and Volume):The transmitters frequency is set using theSet Button (26) and then the(Up) or (Down)Buttons (25). During manual programming,press the Set button to confirm theselection or the selected function will flashfor five seconds and the display will returnto the main menu. To start, press the Setbutton once. The backlight on the lCD (24)will light up and the Group Icon (30) will flash.Use the Up/Down button to change thegroup. When a group selection is finished,press the Set button again for the channel
  • selection. The Channel Icon (31) will nowflash. Again, use the Up/Down button tochange the channel as desired. When theGroup/Channel selection is done, press theSet button again to enter the Volume levelInput (32) setting and then press Up/Down12to change in four steps from 0dB to -30dB(for loudest input) or press the Set button asecond time to exit to the main menu.To change the volume input level only,press the Set button three times to selectthe volume input level setting. Use the Up/Down button to change in four steps from0dB to -30dB (for loudest input). The levelis preset at -10dB for the HT-1KU, which isbest for most applications.For normal operation, the transmittershould have the same Group/Channelas displayed on the receiver. For normaloperation, the transmitter should have thesame Group/Channel as displayed on thereceiver. The default factory setting is Group00 (Transmitter 1), 03 (Transmitter 2), 06(Transmitter 3) and 09 (Transmitter 4), andChannel 00 for all transmitters.After programming is finished, slide thebattery cover back then turn the Mic Ball (23)counterclockwise to secure the housing.The HT-1KU is now ready for use.Note: If you are using multiple transmitters at thesame location, set up the first transmitter and leaveit ON and keep it 3 ft. away from the receivers.Then start AUTO-SCAN on the second receiver.This avoids duplicate selection of the same channelas already selected for the first receiver.If you are not satisfied with a channel afterscanning, repeat again anytime for anotherfree channel.Operating the HT-1KU HandheldTransmitter
  • During normal operation with the unitpowered on, the transmitter power level canbe changed by sliding the RF Power Switch(27) to H to increase the transmittedRF power (for longer range) or to L todecrease the RF power (reduced range).This is a useful feature as the L settingincreases battery life and also optimizesthe number of channels that can be usedsimultaneously in a given location. Usethis setting for normal use not requiringmaximum operating range. A range walktest before use will determine which settingis best for your application.Slide the On/Off switch to the ONposition and the microphone is now readyto use. The receivers RF Signal Meter (12)and one Diversity a or B Indicator (2) shouldnow be on, indicating a received signal fromthe transmitter. Adjust the volume of thereceiver per Connecting Audio Output.Note: Avoid acoustic feedback (howling orscreeching) by taking care in selecting PA volume,transmitter location and speaker placement.The RF Signal meter and the Diversity A or Bindicator on the receivers LCD display should beON in normal operation.BT-1KU Bodypack Transmitter(lT, lT/HM or GT)Buttons FunctionThe RF Power level Switch (44) is used toselect Hi/Low power transmission.When the Set Button (42) is pressed, the LCDmain menu will cycle in the following order:MAIN MENU>CHANNEL>VOLUME>GROUP
  • >MAIN MENU(repeats)The(Up) or (Down) Buttons (41) work inthe set mode only. They can be used tochange any Group/Channel as selected(if not using IR Sync from receiver). Theycan also be used to select the desired Inputaudio level VOL setting. Or they can beused to turn on the LCD display.During manual programming, the selectedfunction will flash for five seconds or pressthe Set button to confirm the selection andthe display will return to the main menu.Setting up the TransmitterThe BT-1KU bodypack requires twoaa Batteries (50) to operate. To install thebatteries into the battery compartment, liftthe Battery Compartment Door (46) by grabbingthe two spring-loaded locking tabs and pullout, exposing the Battery Compartment (45).Insert two fresh AA batteries accordingto the correct polarity as indicated on thetransmitter body. Close the battery cover,ensuring the cover is snapped shut. Freshalkaline batteries can last provide up to 8-10hours of operation, but in order to ensureoptimum performance it is recommendedthat the batteries be replaced after 6-8 hoursof use or as indicated necessary by theflashing Battery Meter BaTT Icon (33).Connecting Input audio SourceUse the audio Input (37) 3.5mm locking minijack for connecting the audio input cordfrom lapel mic (LT), Headmic(LT/HM),or instrument (GT), depending on whichversion transmitter is being used. Securethe connection to the cable by lining up
  • the slot of the 3.5mm mini connector andturning the ring to securely lock in.Powering the Transmitter On/OffTo turn on the transmitter, slide thePower Off/Mute/On Switch (38) to the MUTE(middle) position (transmitter on, audiomuted). The LCD backlight will light up.The unit is now on. After ten seconds thebacklight will automatically turn off. TheGroup (30), Channel (31), Input Volume level (32)and Battery Meter (33) remain on in normaloperation.As many of the five LCD battery levelsshould stay lit as possible, indicating usablebattery strength. As the batteries weaken,fewer of the level indicators stay lit untilonly one bar shows, which will then flashto warn that the batteries are now too low13and should be replaced as soon as possible.To preserve battery life, turn the transmitteroff when not in use. To turn the transmitteroff, slide the Off/Mute/On switch toMUTE and then OFF. The LCD willdisplay OFF, no LCD or backlight is litup and the unit will be off.At Power Off the transmitter will storethe last settings entered and re-displaythem at the next power on where it can bereprogrammed to any new Group/Channelor Volume level at the first time of use oranytime later. The factory default settingfor Volume 0dB is same for all transmitters.These settings are optimal for mostapplications.Programming the BT-1KUto the Selected ChannelThe transmitter can be programmed to thesame frequency as selected for the receiver,either via automatic synchronization using
  • the IR Sync function or manually on thetransmitter itself.IR Sync Programming:Use the wireless IR leD Receptor Sensor (43)to download pre-programmed channels fromthe receiver. Start programming by holdingthe IR LED Receptor about 6-12 fromthe receivers IR leD Window (4), then pressthe IR Sync Button (5) on the receiver to beused. When short pressing the ASC IR SyncButton, while the main menu is displayed,the IR LED will light up red for about threeseconds. This indicates IR transmission is inprogress and IR data is transferring duringthis period. Upon successful data transfer(usually in about three seconds) the IR LEDstops and the transmitters backlight willlight up and the transmitter will transmita radio signal on the same channel as thereceiver. The Signal Strength and DiversityIndicators on the receivers LCD display willthen light up, indicating that the IR link iscompleted.14Note: If procedure is not done correctly during thethree seconds of active data transfer, the receiverand the transmitter do not link and transmittersprevious programmed channel remainsunchanged.The IR link is infrared light and thus works bestwhen this data transfer is accomplished in alight-shielded or darker environment. It may notbe successful in a brightly lit area. If the transferfails, repeat the procedure in a darker locationor somehow shield the link from outside light tosuccess-fully program the transmitter with thepre-programmed group and channel info fromthe receiver.Manual Programming (GRP/CH and Volume):The transmitters frequency is set using theSet Button (42) and then the
  • (Up) or (Down)Buttons (41). During manual programming,the selected function will flash for fiveseconds, or press the Set button to confirmthe selection and the display will returnto the main menu. To start, press the Setbutton once. The backlight on the lCD (40)will light up and the Group (30) icon will flash.Use the Up/Down buttons to change thegroup. When a group selection is finished,press the Set button again for the channelselection. The Channel Icon (31) will nowflash. Again, use the Up/Down buttons tochange the channel as desired. When thegroup/channel selection is done, press theSet button again to enter volume level inputsetting and then press Up/Down button tochange in four steps from 00dB to -30dB(for loudest input) or press the Set button asecond time to exit to the main menu.To change volume input level only, press theSet button three times to select the volumeinput level setting. Use the Up/Down tochange in four steps from 0dB to -30dB(-30dB for loudest input). The level is presetat -10dB for LT/HM and 0dB for GT. Thesesettings are optimal for most applications.For normal operation, the transmitter shouldhave the same Group/Channel as displayedon the receiver. The default factory settingis Group 00 (Transmitter 1), 03 (Transmitter2), 06 (Transmitter 3) and 09 (Transmitter 4),and Channel 00 for all transmitters. Afterprogramming is finished, close the batterycompartment door, ensuring that it latches.The BT-1KU is now ready for use.note: If you are using multiple transmitters atthe same location, set up the first transmitterand leave it ON and keep it 3 ft. away from thereceivers. Then start AUTO-SCAN on the secondreceiver. This avoids duplicate selection of the
  • same channel as already selected for the firstreceiver.If you are not satisfied with a channel afterscanning, repeat again anytime for anotherfree channel.Operating the BT-1KUBodypack TransmitterDuring normal operation with the unitpowered on, the transmitter power level canbe changed by sliding the RF Power Switch(44) to H to increase the transmittedRF power (for longer range) or to L todecrease the RF power (reduced range).This is a useful feature as the L settingincreases battery life and also optimizesthe number of channels that can be usedsimultaneously in a given location. Usethis setting for normal use not requiringmaximum operating range. A range walktest before use will determine whichsetting is best for your application.The Power Off/Mute/On Switch (38) has threepositions and functions both as a poweron/off and as an audio mute on/off switch.After the unit is powered on, slide thepower switch to the ON position to un-mute the audio. With Power Off/Mute/Onswitch in either in MUTE or ON positionthe receivers RF Signal Meter (12) and oneDiversity a or B (3) indicator should now beon, indicating a received signal from thetransmitter. When ready to transmit audio,slide the power switch to ON to un-mute.To mute, slide the power switch to MUTEagain. Adjust the volume of the receiver perConnecting Audio Outputs section above.Note: Avoid acoustic feedback (howling orscreeching) by taking care in selecting PA volume,transmitter location and speaker placement.The RF Signal meter and the Diversity A/Bindicator on the receivers LCD display should be
  • On in normal operation.Instrument Use (BT-1KU/GT only)Secure the connection of the GT(instrument) cable by lining up the slotof the 3.5mm mini locking Input Jack (37)connector and turning the ring to securelylock in. When ready to play, slide the PowerOff/Mute/On Switch (38) to ON positionto un-mute the audio. Adjust the volumelower on the receivers Unbalanced audioOutput (17) for one-to-one unity gain with ahardwired cord or select up to an added4-5dB boost by leaving the receiver volumeto maximum for normal use with guitarsand bass guitars. Note this function is bestwhen using two transmitters for switchingduring performance as these is only a singlemixed output from the two receivers. If anindividual output per receiver is desired, usethe XlR Mic Outputs (15), noting that thoseare only fixed Mic level outputs.Note: The audio level should be adjusted onthe instrument as when using a hard-wired cord.For most applications the transmitters InputVolume Level (32) should be set at 0dB for optimalperformance. Use attenuation levels (-10dB, -20dB,-30dB) only for higher output instruments, such asbass guitars with active pickups, and then only ifneeded for cleaner sound.15SpecificationsSYSTeM OVeRall SPeCIFICaTIOnSOperating Frequency Range(U.S.) Band 1: 672.000-696.975MHz, (Int.)

However, they pick up soundsources best that are directly in front of themic. Also mics that are farther from thesound source require more acoustic gainand thus are also more prone to feed backthan close-source mics such as handheld.no or low audioIf you are not getting audio through thesystem, carefully re-check all setups.Especially note that the receiver andtransmitter must be set to operate on thesame RF channel. For BT-1KU bodypacktransmitter, also confirm that the PowerOff/Mute/On Switch (38) is not in the Muteposition. The receivers Unbalanced linelevel Out (17) is adjustable so make surethe Volume (11) is set properly.RF Interference andFinding Open Channels
  • If you encounter slight receiving interferencewhen the transmitter is far from the receiver(from other than an operating TV stationon the same frequency), often it can beovercome by adjusting the receiversSquelch Control (16) (see Adjusting theSquelch). If receiving interference on aselected channel with the transmitteroff, you must reprogram the receiverand transmitter to a different channel.See: Selecting the 4W-1KU QUAD ReceiverVolume Level / Group / ChannelProgramming the HT-1KU/BT-1KUto the Selected ChannelTo reprogram, you must first find an openchannel. To do this, follow the operatingprocedure outlined in Selecting the 4W-1KUReceiver Volume Level / Group / Channel.With the associated transmitter off, scrollthrough the groups/channels to find onethat shows no received signal on thereceivers RF Signal Meter (12) (no bars).Also, there must be no bars either on eachof the three immediately adjacent channelsboth above and below the selectedchannel for optimum interference-freeoperation (i.e. in a field of seven adjacentchannel total with the channel used inthe middle). If operating multiple 4W-1KUSeries systems simultaneously, repeat thisprocedure with every new channel beingselected, with previously tuned systems allon, both transmitters and receivers.Please note that wireless frequencies areshared with other radio services. Accordingto FCC regulations, wireless microphoneoperations are unprotected frominterference from other licensed operationsin the band. If any interference is receivedby any Government or non-governmentoperation, the wireless microphone must
  • cease operation or change frequencies.The above statement is valid only for usein the U.S.A.Note: More bars in the Received Signal (12) iconindicate good signal strength in operation with thetransmitter on, but more than 1 bar showing withthe transmitter off also indicates the presence oflikely RF interfering signals at that location. If thishappens, select a different GRP/CH. One bar orless is ideal for interference-free operation.17Miscellaneous TipsFor optimal operation with externalantennas, low loss RF shielded cable18should be used and the length of thecable should not exceed 10 ft. (3 m).The receiver antennas should be keptaway from any metal surfaces wheneverpossible as they can reflect away orshield the incoming RF signal.If the receivers volume control is settoo high, it may overdrive the inputof the attached audio mixer, causingdistortion. Conversely, if the output is settoo low, the overall signal-to-noise ratioof the system may be reduced, causingnoticeable hiss. If such noise occurs,adjust the output level of the receiverso that highest sound pressure levelgoing into the microphone transmittercauses no input overload in the mixer, butpermits the mixer level control to operatein the normal range (not too high andnot too low). This provides the optimumsignal-to-noise for the entire system.Before inserting the batteries, ensure thatthey are inserted with the correct polarity.Before operation, confirm that thereceiver and associated transmitter aretuned to the same frequency group and
  • channel number.After making a receiver channel change,ensure that the corresponding change isalso made on the matching transmitter.Use only brand new alkaline batteries.Do not use general purpose carbonbatteries. When batteries are weak,replace all the batteries at the same time.Do not mix new and old batteries.Position the receiver so that it has the leastpossible obstructions between it and thetransmitter. Line-of-sight is best!During operation, the transmitter and thereceiver should be as close as possible foroptimum results but never closer than 3 ft.(1 m) as that may overload the receiversinput circuitry and cause noises.For the best operation, the receiver shouldbe placed at least 3 ft. (1 m) above theground and 3 ft. (1 m) away from a wall ormetal surface. The transmitter should alsobe at least 3 ft. (1 m) from the receiver.Keep antennas away from noise sourcessuch as motors, automobiles, neon lights,signal processors, computers, as well aslarge metal objects.A receiver cannot receive signals fromtwo or more transmitters simultaneously.Turn the transmitter off when it is notin use. For longest life, remove thebatteries if the unit is not to be used fora long period as the transmitters drawa tiny residual current to maintain theprogrammed settings, even when turnedoff. Also, since batteries installed for along time can sometimes corrode and/orleak, causing damage, it is generallyrecommended that batteries be removedwhenever the transmitters are notbeing used.When using the BT-1KU bodypack for
  • instrument use: Scratchy noises cansometimes occur when an electric guitarwith dirty pots or connections is used witha wireless system. Therefore, the suppliedcapacitor provides first-order filtering ofthe RF signal from the cord into the guitarand eliminates virtually all scratchy noises.Should your equipment still producescratchy noise, we suggest these stepsto eliminate problems:1) Make sure all guitar volume and tonepots are clean and all contacts are solid.This is very important.2) Solder a 47pF capacitor across the potto ground terminal of the guitars volumeand tone pots to provide extra filtering.FrequencyFrequency PlanBand 1 (U.S.): 672.000-696.975MHzBand 2 (International): 795.000-819.975MHz25KHz per step (1000 Channels) U.S.AccessoriesPart number DescriptionIC-U1K Instrument cable included for BT-1KU/GT transmitter,3.5mm locking mini plug toService InformationIn the U.S. If you are experiencing operational problems with your system, please refer tothe Support page at www.nady.com for assistance.
