MIXER 101
The Mixer The Wall of Sound was comprised of 586 JBL speakers and 54 Electrovoice tweeters powered by 48 MacIntosh 2300 Amps (48 X 600 = 28,800 Watts of continuous (RMS) power.

What Does A Mixer Do ? An audio mixer brings all the parts of a performance together blending and processing them so that the final sound makes sense to the audience and is good to listen to

Input Gain Controls The GAIN control is used to adjust the input sensitivity of the mixer to incoming sounds

The GAIN should be adjusted while the microphone is being used in a typical fashion so that the ZERO LEVEL LED is flickering The Pre-Amp for each channel provides up to 50dB of amplification Low Cut (High Pass) filter switch cuts frequencies below 100Hz
Input Gain Controls If the signal level is too low then it will be noisy If the signal level is too high then it will be distorted

Routing - AUX (Auxiliary) These controls send the channel signal to an external device for parallel effects processing or to stage monitors For parallel effects processing, use the AUX controls in post-fader mode (switch up) For stage monitors, use the AUX controls in pre-fader mode (switch down)

The levels are set independently of the MAIN mix using the MASTER SEND AUX knobs
Routing - AUX (Auxiliary) Insert Jack for connecting serial effects such as compressors, equalizers, de-essers To create a stage monitor mix, patch the AUX SEND outputs to a monitor amplifier using TRS cables
MIXER 101
Routing - EFX (Effects) These controls send the channel signal to an external effect device (EFX1) or the internal effects processor (EFX2) EFX1 and EFX 2 are always in post-fader mode so any changes to the channel controls will affect the EFX1 or EFX2 signals The EFX1 levels are set independently of the MAIN mix using the EFX 1 (EXT) knob MIXER 101
Channel Equalization The channel equalization controls allow for fine frequency tuning of the channel signal Controls are divided into High, Mid and Low frequency ranges Turning the knobs to the left of ‘U’ (Unity) cuts and turning the knobs to the right to boosts a particular frequency range

Pan The PAN control adjusts the amount of channel signal that is sent to the left or right SUB OUT (and ultimately) MAIN OUT channels The PAN control allows the engineer to position the instruments within the stereo image sent out of the MAINS OUT
MIXER 101
Input Fader The FADER is the master level control for the channel signal If the GAIN for the channel is properly set, the FADER should be set somewhere between 0dB (U - Unity) and -30dB The MUTE button mutes the channel signal and removes it from the SUB or MAIN mixes

The ASSIGN buttons are used to assign the channel signal to a SUBMIX
