any residual cleaner. Never use volatile clean-  
ers such as benzene, solvent, or thinner to clean  
your unit, these cleaners will damage the units

not damage or deform; it may cause electric  
shock or malfunction when used. Hold plug  
attachment when removing from wall outlet.

QUICK START INSTRUCTIONS  
QUICK START: American Audio® would like to thank you for your purchase of this great audio product.  
For those of you that are too impatient to read the entire user manual we have compiled these quick  
start instructions. We hope that you will at least read through these instructions to familiarize yourself  
with the basics of this mixer. The Q-2422 MKII™ is part of American Audio’s continuing evolution in  
audio technology. This unit has been built and designed to meet the needs of a typical DJ. We have  
attempted to provide you with the most reliable product on the market by using only components con-  
structed of the finest material.  
MASTER LEVEL - Use this level to control your main volume output. Try never to send an output of  
more than +4dB to your system. Signal at levels higher than this will start to distort and may cause  
damage to your system and speakers. Remember that a distorted signal from you mixer will only be  
multiplied throughout your system.  
CHANNEL GAIN LEVEL - The channel gain levels are not to be used as volume controls. Never use  
the channel trim to set the output volume. These controls are used to aid in distortion control. Use  
these control to preset your signal level before the crossfader. With your channel faders in the maxi-  
mum position, use the channel trim level to set an average output level of about +4dB on your master  
level meter.  
HEADPHONES - To avoid damaging your headphones always be sure the headphone volume level  
(16) is set to minimum before plugging them in. To avoid sever hearing damage, never put the head-  
phone on without making sure the headphone level is turned down.  
MAIN MIC - The main mic connector uses a combo plug that allows you to connect either a 1/4”  
unbalanced jack or by a standard 3-pin XLR balanced connector. The main mic also has an indepen-  
dent volume control. When feedback occurs when using the mic, try lowering the level this may reduce  
the feedback. Always leave the mic level to it’s minimum level when not in use. Note: We recommend  
that you use a 500-600ohm microphone for the best sound quality.  
PHONO/AUX LINE LEVEL SELECTOR SWITCH - This switch is used to change the selected input  
from phono to line and vice versa. The switch selectors are on the rear panel.
