the “phono” position for turntable operation.
5. CHANNEL GAIN CONTROL - This adjustment is used to adjust the audio source signal input gain
for a channel. Never use the gain control to adjust a channels output volume. Setting the gain level
properly will ensure a clean output signal. An improper gain level adjustment will send a distorted
signal throughout the entire audio line which may damage speakers and amplifiers. To properly set a
channels gain level control:
1. Be sure the MASTER VOLUME CONTROL (22) is set to level 8.
2. Set the CHANNEL FADER (25) to level 8.
3. Begin playback on an audio source connected to the channel you are adjusting.
4. Use the Gain Control to adjust an average output volume of +4 dB.
5. Repeat this step for all channels
6. Q-START ON/OFF BUTTON - This function works in conjunction with a compatible American DJ®
or American Audio® “Q” Start CD player. When used with a compatible CD player, you can use the
crossfader to start and stop a CD Player with the slide of the mixer’s CROSSFADER (28). The ON/OFF
“Q" START BUTTTON activates the FADER “Q" START feature. When in the ON position (RED LED
WILL BE LIT), the FADER “Q" START automatically returns the CD player to the preset CUE POINT.
For example; Assuming you have two compatible American Audio™ CD players or a
compatible dual CD player connected to channels one and two. When the Fader "Q" Start
option is turned on, sliding the crossfader to the far left position will trigger playback on CD
player 1. When the crossfader is pushed to the far right position, playback on CD player 2 will
begin, and CD player 1 will return to the cue position. Refer to your American Audio CD player
user manual for setting CUE POINTS. Turn the ON/OFF BUTTON to the OFF position (RED
LED IS NOT LIT) to disengaged “Q” Start function and resume to a normal fader.

8. CHANNEL VOLUME LEVEL INDICATORS - The LED indicators that run along each channels EQ
section are used to measure incoming signal levels. Use these indicator to visually maintain an average
signal output of +4dB. A consistent average output level of +4dB will produce a clean output signal.
9. MASTER VOLUME LEVEL IN DICATORS - The dual MASTER LEVEL LED indicators are used to
