TWO AA ALKALINE BATTERIES43477System OperationButtons FunctionThe Power Button (6) is used to turn bothreceivers ON or OFF at the same time.When this power button is pressed, the bluebacklights on the lCD Displays (7) will lightup indicating the receivers are on. Press thePower button again to turn off the receivers.The LCD will display OFF then the backlightwill turn off indicating the receivers are off.At power-off the 2W-1KU receivers willstore the last settings entered and re-displaythem at power-on. It can be reprogrammedto any new Group/Channel, or Volumelevel. The default factory setting is Group04 (Receiver 1) and 05 (Receiver 2), andChannel 00, Volume 63 for both receivers.The (Up) or (Down) Buttons (4) are activewhile in the Set mode, or can be used tochange Volume level (11) at anytime.When the Set Button (3) is repeatedlypressed the LCD display 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 within82W-1KU Receiverthe frequency band (with all TXs turnedoff at this time).

    • 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 (1) 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 Programmingin Programming sections of HT-1KUand BT-1KU transmitter sections).Upon successful data transferred (usuallyin about 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 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 anytime for locating anotherfree channel.Selecting the 2W-1KU ReceiverVolume level / Group / ChannelThis section will also aid in finding desiredchannel(s) of operation when setting upyour system(s).Press the Set Button (3) three times to
    • check the current Volume levels (11) setting.To change the Volume levels, press the(Up) or (Down) Buttons (4) 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.Choose the 2W-1KU operating frequencyby selecting one of ten Groups (9) and oneof 100 Channels (10) that are determined tobe desirable open channels. Press the Setbutton to enter the Group setup mode andthe Group icon will flash, then press theUp/Down button once for single steppingthrough the groups, or hold continuouslyfor faster group selection. Select one of tengroups available from the Group menu andthen press the Set button again for ChannelSetup mode and the Channel icon will flash,or press the Set button twice to exit withoutchanging the channel. In the Channel setupmenu. Press the Up/Down button oncefor single stepping through the channels,or hold continuously for faster channelselection. Select one 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 thedisplay 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 2W-1KU dual receiver wirelesssystem includes a rackmount kit for frontantennas mounting. Simply attach the L
    • shape Rack ears (21) to the unit with thesupplied screws.Note: Do not mount the receiver on a rack directlyabove an amplifier or other source of high heat.This could degrade the performance of the2W-1KU. Always ensure adequate airflow andheat dissipation in any rack configuration.Installing antennasInstall antennas by connecting the twoantennas (20) included with your systemonto the two RF Connectors (15) locatedon the back of the 2W-1KU receiver. Thetwo antennas must be installed in order tothe diversity circuit to work properly. Theoptimal positions of the antennas are 45from the receiver and 90 from each other.For maximum range, it is always best tomaintain a line-of-sight (no obstructions)between the receiver antennas and thetransmitter at all times whenever possible.To install optional antenna extension Cables(22), insert one end of each cable into a rackear hole and secure using the removablenut. Clip the other end of the cable to anRF Connector (12) on the back of the unit.Connect the two antennas to the front ofthe system.Powering the ReceiversTo power the receivers, plug the suppliedAC/DC Power Supply (19) adapter intothe DC Input Jack (14) on the back of thereceivers, then plug the adapter into anAC outlet.Note: Any 16-18VDC power source with 800mAminimum capacity can also be used.To turn on, press the Power Button (6)for two seconds. The lCD Display (7) willlight (showing Group, Channel, RF LevelMeter, Diversity, and Output Volume).The 5-segment aF leD Tree (5) will displaythe audio level when the transmitter is on
    • (audio is transmitted). To turn off, press thePower button for two seconds. The LCD willdisplay OFF then the backlight will turnoff indicating the receivers are off.Connect either the Unbalanced SUM lineOut (18) or each XlR Balanced Mic Outs (17)to your mixing board, effect, or amplifierinputs (See Connecting the Audio Outputssection).9adjusting the SquelchIn normal operation, each 2W-1KU receiversMute Control (16) works independently andshould be adjusted clockwise (CW) to theminimum RF squelch setting at which theRF level Meter (12) and one of the DiversityIndicators (8/13) will remain on while yourtransmitter is in normal use, up to themaximum operating range anticipated in usefor your application. However, in areas ofhigh RF activity, the Mute control may needto be adjusted counterclockwise (CCW).If the transmitter is off and the RF SignalMeter (12) and Diversity Indicators (8/13) areflickering or stay on continuously, the Mutelevel should be adjusted higher level CCW(counterclockwise for less mute sensitivitylevel) to stop the flickering. Be careful notto adjust a too high CCW setting as thismay reduce the operating range to belowwhat is needed. A range walk test will helpin selecting the proper level. If the rangeis not 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 Indicator
    • The 2W-1KU receiver has two 5-segmentaF/Peak leDs Displays (5) and each worksindependently per receiver. The AF/PeakLEDs light up sequentially, indicatingthe level of the audio signal from thetransmitter. Occasional flickering of thetop (red) Peak LED on loud inputs to thetransmitter is normal. If the Peak LED lightscontinuously decrease the input audio levelto the transmitter or overload distortionmay result.10Connecting the audio OutputsThe 2W-1KU receiver has one Unbalancedaudio SUM Out (18) adjustable line levelaudio output and two Balanced XlR MicOut (17) fixed level jacks and each worksindependently per channel. The UnbalancedAudio Out is controlled by (Up) or(Down) Buttons (4). The receiver VolumeDisplay (12) will indicate the level selected.For unbalanced output, plug a mono(Tip/Sleeve) audio cable into the UnbalancedAudio Out jack and plug the other end intoyour mixing board or amplifier. When usingthe BT-1KU instrument transmitter system,connect the Unbalanced Audio SUM Outdirectly to your instrument amp or preamp.At maximum receiver volume setting, asindicated by the Volume display, the systemoutput is approximately +4dB higher than adirect cord-to-amp connection.Note: Both receivers output will be mixed togetheras per the individual receivers volume settingsas selected by the up/down volume controls.If separate signals are required for each instrumentthen the XLR outputs must be used, however, notethey are not line level or adjustable. The SUM outis best utilized for switching between separatetransmitters during performance with only one audio
    • signal at a time fed to the instrument amplifier.For balanced output, plug an audio cable with anXLR connector into the XLR Balanced Mic Outsocket for each receiver and plug the other end intoyour mixing board or amplifier inputs accordinglyAs when making any connection, make surethe amplifier or mixing board volume is at theminimum level before plugging in the receiverto avoid possible sound system damage.Your 2W-1KU receiver is now operationaland ready to use. Once you have completedthe above steps, proceed to the followinginstructions for the HT-1KU handheld orBT-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 two receiver unit, twotransmitters on separate frequencies can beutilized, one with each receiver.HT-1KU HandheldMicrophone TransmitterButtons FunctionThe RF Power level Switch (33) is used toselect Hi/Low power transmission.Each time the Set Button (32) is pressed, theLCD menu will cycle in the following order:MAIN MENU>CHANNEL>VOLUME>GROUP>MAIN MENU(repeats)The(Up) or (Down) Buttons (31) work inthe set mode only. They can be used to
    • change 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 (24) by turningcounterclockwise until loose and slide downthe cover, exposing the Battery Compartment(37). Insert two fresh AA batteries accordingto the correct polarity as indicated on thetransmitter body. Screw the battery coverback onto the microphone, making sure it issecurely tightened. Fresh alkaline batteriescan provide up to 8-10 hours of operation,but in order to ensure optimal performanceit is recommended that the batteriesbe replaced after 6-8 hours of use or asindicated to be necessary by the flashingBattery BaTT Meter Icon (30).Powering the Transmitter On/OffTo turn on the transmitter, slide thePower On/Off Switch (34) to the ONposition. The LCD backlight will light up,indicating the unit is now on. After tenseconds the backlight will automaticallyturn off to conserve battery life. The Group(27), Channel (28), Input Volume level (29), andBattery Meter (30) indicator icons stay onfor normal operation.As many of the LCD battery levels shouldstay lit as possible, as they indicate usablebattery strength. As the batteries weaken,
    • fewer of the level indicators will stay lit untilonly one bar shows, which will then flash towarn that the batteries are now too low andshould be replaced as soon as possible withfresh ones.To preserve battery life, turn the transmitteroff when not in use. To turn the transmitteroff, slide the power on/off switch to theOFF position. The LCD will display OFF,no LCD or backlight is lit up and the unit willbe 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 setting forVolume -10dB is same for all transmitters.These settings are optimal for mostapplications.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.11IR Sync Programming:Use the wireless IR leD Receptor Sensor (36)to download pre-programmed channelsfrom the receiver. Start programming byholding the IR LED Receptor about 6-12from the receivers IR leD Window (1), thenpress the IR Sync Button (2) on the receiverto be used. When short pressing the aSC IRSync Button (2), while the main menu isdisplayed, the IR LED will light up red andstay for about three seconds. This indicatesIR transmission is in progress and IR datais transferring during this period. Upon
    • successful data transfer (usually in aboutthree seconds) the IR LED stops and thetransmitters 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 light up,indicating that the IR link is completed.Note: 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 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 (32) and then the(Up) or (Down)Buttons (31) . 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 (26)will light up and the Group Icon (27) will flash.Use the Up/Down buttons to change thegroup. When a group selection is finished,12press the Set button again for the channelselection. The Channel Icon (28) will nowflash. Again, use the Up/Down buttons tochange the channel as desired. When theGroup/Channel selection is done, press the
    • Set button again to enter the Volume levelInput (29) setting and then press Up/Downto change in four steps from 00dB to -30dB(for loudest input) or press the Set buttonthe again 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 from00dB to -30dB (for loudest input). The levelis preset at -10dB for the HT-1KU, which isbest for most applications.For normal operation, the transmitter shouldhave the same Group/Channel as displayedon the receiver. The default factory setting isGroup 04 (Transmitter 1) and 05 (Transmitter2), and Channel 00 for all transmitters.After programming is finished, slide thebattery cover back then turn the Mic Ball (25)counterclockwise to secure the housing.The HT-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 thesame channel as already selected for the firstreceiver.If you are not satisfied with a channel afterscanning, repeat again anytime for anotherfree channel.Operating the HT-1KUHandheld TransmitterDuring normal operation with the unitpowered ON, the transmitter powerlevel can be changed by sliding theRF Power Switch (33) to H to increase thetransmitted RF power (for longer range) orto L to decrease the RF power (reducedrange). This is a useful feature as the Lsetting increases battery life and also
    • optimizes the number of channels that canbe used simultaneously in a given location.Use this 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 ready touse. The receivers RF Signal Meter (12) andone Diversity a or B (8/13) indicator shouldnow be on, indicating a received signal fromthe transmitter. Adjust the volume of thereceiver per Connecting the Audio Outputsection 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 or Bindicator on the receivers LCD display shouldbe ON in normal operation.BT-1KU Bodypack Transmitter(lT, lT/HM or GT)Buttons FunctionThe RF Power level Switch (45) is used toselect Hi/Low power transmission.When the Set Button (44) is pressed, the LCDmain menu will cycle in the following order:MAIN MENU>CHANNEL>VOLUME>GROUP>MAIN MENU(repeats)The(Up) or (Down) Buttons (43) 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 two AA sizebatteries to operate. To install the batteriesinto the battery compartment, lift theBattery Compartment Door (48) by grabbingthe two spring-loaded locking tabs and pullout, exposing the Battery Compartment (47).Insert two fresh aa batteries (50) 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 (30).Connecting Input audio SourceUse the audio Input (40) 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 upthe 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 (41) to the MUTE(middle) position (transmitter on, audio
    • muted). The LCD backlight will light up.The unit is now on. After ten seconds thebacklight will automatically turn off. TheGroup (27), Channel (28), Input Volume level (29)and Battery Meter (30) 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 flash towarn that the batteries are now too low and13should be replaced as soon as possible. Topreserve battery life, turn the transmitter offwhen not in use. To turn the transmitter off,slide the Off/Mute/On switch to MUTEand then OFF. The LCD will displayOFF, no LCD or backlight is lit up and theunit 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 usingthe IR Sync function or manually on thetransmitter itself.IR Sync Programming:Use the wireless IR leD Receptor Sensor (45)to download pre-programmed channels fromthe receiver. Start programming by holdingthe IR LED Receptor about 6-12 from
    • the receivers IR leD Window (1), then pressthe IR Sync Button (2) 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.

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 (44) and then the(Up) or (Down)Buttons (43). 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 (39)
    • will light up and the Group (27) 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 (28) 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 thesame 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 Transmitter
    • During normal operation with the unitpowered on, the transmitter power levelcan be changed by sliding the RF PowerSwitch (46) to H to increase thetransmitted RF power (for longer range) orto L to decrease the RF power (reducedrange). This is a useful feature as the Lsetting increases battery life and alsooptimizes the number of channels that canbe used simultaneously in a given location.Use this 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 (41) 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 unmutetheaudio.WithPowerOff/Mute/OnswitchineitherinMUTEorONpositionthe receivers RF Signal Meter (12) and oneDiversity a or B (8/13) indicator should nowbe on, indicating a received signal from thetransmitter.

When ready to play, slide the PowerOff/Mute/On Switch (41) to ON positionto un-mute the audio. Adjust the volumelower on the receivers line level SUMOutput (18) 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 (17), 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 (29) 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.

The receivers Unbalanced linelevel Out (18) is adjustable so make surethe Volume (11) is set properly.RF Interference andFinding Open ChannelsIf 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 receivers SquelchControl (16) (see 2W-1KU Receiver: Adjustingthe Squelch). If receiving interference on aselected channel with the transmitter off,you must reprogram the receiverand transmitter to a different channel.See: Selecting the 2W-1KU Receiver VolumeLevel / 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 2W-1KUReceiver Volume Level / Group / Channel.With the associated transmitter off, scrollthrough the groups/channels to find one thatshows no received signal on the receiversRF Signal Meter (12) (no bars). Also, theremust be no bars either on each of thethree immediately adjacent channels bothabove and below the selected channel foroptimum interference-free operation (i.e. ina field of seven adjacent channel totalwith the channel used in the middle). Ifoperating multiple 2W-1KU Series systemssimultaneously, repeat this procedurewith every new channel being selected,with previously tuned systems all on,both transmitters and receivers.Please note that wireless frequencies areshared with other radio services. According
    • to 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 mustcease 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 optimum
    • signal-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 andchannel 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 a
    • long 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 forinstrument 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.
