This document discusses sound equipment including speakers, microphones, and a sound desk. It provides details on: - Active speakers have built-in amplifiers while passive speakers require an external amplifier. Speakers come in subwoofer and tops models of varying sizes. - Microphones can be condenser or dynamic, with condensers being more sensitive but requiring phantom power. Wireless microphones transmit signal to a receiver. - A sound desk allows adjusting input and output levels from various sources to mix and send sound through different outputs. It has channels, gain knobs, EQ knobs, auxiliary cables, and faders to control the sound. - Amplifiers power electrical signals from the sound

Speakers
There are twomain typesof speakers, active andpassive.
Active speakershave aninbuiltamplifierinthe bodyof the speakerwhereaspassive speakersneed
an external amplifiertofunction.
Here are subsspeaker.They’re goodforlower

generallysmall insize because theydon’thave tocope withheavybases

A sounddesk allowsyoutoadjust
the inputsandout puts of a
differentlevelsof sources,soyou
can mix and adjustthe levelsof
soundto sendoutto another
output.
Thisdeskhas 16
channels
howeverourone
has 32, whichis
more than
enoughforwhat
use use it for
(concerts,talent

presentations
ect)
Thisis the gain,these knobshelp

These are the eqknobs,withthese
youcan boostor cut the

These are the aux cables.This

wantto hear specificsounds)
These are faders,these givesthe
mix level tothe differentoutputs
and can alsocontrol the soundfrom
these aswell.

3. Amplifiers
An amplifiersendspowerof the electrical signalssothattheycan thenbe sentto the speaker.They
are connectedtothe sounddeskbyan XLR cable andby a cable to a passive speaker.Active
speakersare typicallyonlyhave one channelbutpassive speakerswill generallyuse stereososound
can be sentto whereverthe operatorwantsitto go.
Microphone
There are twomaintypesof microphones,condensersanddynamicmic’s.Dynamicmicrophonesare
normallylesssensitive andtherefore betterfor
loudernoisesandlowerfrequencies(ie:drum
kit) but a condensermicrophone needsan
external powersupply(phantompower),this
will enhance the signal of the microphonesoit
ismakingit muchmore sensitive andbetterfor
quieternoises(ie:vocals,violinsect) andcould
alsomake the qualityof the soundbetterin
some cases.Both microphones(condensers,
dynamic) are generallyconnecteddirectlyto
the deskby an XLR cable howeveryoucanget
signal transmitterthatcan senditwirelessbut
the signal can be intercededanddisruptedand
the soundqualitycandecrease.
Anothertype of microphone are radiomic.Theysendthe signal wirelesslytoareceiver separate

channel.Because they’re wirelessthey’regoodfortheatresasthe actor/rescan move aroundthe
stage withthemhowevertheycanhave some interference due toitbeingwireless.

4. ThisIs the soundlay outfor the Ringwood’sfortalent.We had3 mice (1 wirelessradiomicand2
condensermics).We hadone dynamicmicfor the setupof the drumkitand the rest condensers( 1
for the snare,1 forthe lowtom, 2 for the midtoms, and2 for the symbols).We hadtwostandsfor
the condensermicsforthe symbolsso theywere above themsowe couldget the bestsoundfrom
them.
