QUICK START  
American Audio would like to thank you for your purchase of this great product. For those of you that  
are to 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 basic under-  
standing of the unit. The Q-2422/SX is part of American DJ’s continuing evolution in audio technol-  
ogy. This unit has been built and designed with the typical DJ in mind, by DJ’s. We have attempted to  
provide you with the most reliable product on the market by only using components made from quality  
products.  
MASTER LEVEL - Use this level control to set your volume output. Try never to send an output of  
more than +4dB to your system. A 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 your mixer will only be  
multiplied throughout your system.  
CHANNEL TRIM LEVEL - The channel trim 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  
this control to preset your signal level before the crossfader. With your channel fades in the maximum  
position, use the channel trim level to set an average output level of about +4dB on you master level  
meter.  
HEADPHONES - To avoid sever hearing damage always be sure the headphone level is set to mini-  
mum before plugging them in. Never put the headphones on without making sure the headphone level  
is turned down.  
MAIN MIC - The main mic connector uses a Nuetrik combo plug which 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  
independent volume control with separate high and low level adjustments. If feedback occurs when  
using the mic, try lowering the “low” frequency level, this may reduce feedback. Always leave the mic  
level to it’s minimum level when not in use.  
PHONO/AUX/LINE SWITCH (5) - This switch is used to change the selected input from phono to line  
and vice versa. Channels 1 and 2 may be switched PHONO/AUX or LINE. Channel 3 may be switched  
LINE 3 or LINE 4. The selectors for AUX1/PHONO1 and AUX2/PHONO2 are on the rear panel (36).

FRONT PANEL - CONTROLS AND FUNCTIONS  
1. POWER SWITCH -  
This is the main power ON/OFF button. A yellow LED below the power switch will glow when power is  
ON. Before you turn the power on be sure you have made all connections to the mixer. Also be sure you  
amplifiers are turned off. Remember mixer on first and turned off last.  
2. MASTER LEVEL INDICATORS -  
The dual MASTER LEVEL LED indicators along the top of unit is used to detail the master output  
level. The meter will detail the output level of the left and right channels.  
3. CHANNEL GAIN CONTROL -  
This adjustment is used to adjust an audio source signal input gain for a channel. Never use the gain  
control to adjust 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. To prop-  
erly set the gain level control:  
1. Be sure the MASTER VOLUME CONTROL (13) is set to minimum (zero output).  
2. Set the CHANNEL FADER (6) to level 7.  
3. Begin play on an audio source connected to the channel you are adjusting.  
4. Turn the CUE (7) function on for the channel you are adjusting.  
6. Use the GAIN CONTROL to adjust an average output volume of +4 dB in the LED  
LEVEL INDICATOR (2).  
4. CHANNEL EQ SECTION -  
CHANNEL BASS EQUALIZER - Each of the three channels come with a BASS signal output  
EQ. These controls are used to increase (up to +15dB) or decrease (down to -35dB) the LOW  
range output signal. Turn the knob counter-clockwise to decrease a value or clockwise to  
increase a value.  
 
FRONT PANEL - CONTROLS AND FUNCTIONS CONT.  
CHANNEL MID RANGE EQUALIZER - Each of the three channels come with a MID signal  
output EQ. These controls are used to increase (up to +15dB) or decrease (down to -30dB) the  
MID range output signal. Turn the knob counter-clockwise to decrease a value or clockwise to  
increase a value.  
CHANNEL TREBLE FREQUENCY EQUALIZER - Each of the three channels come with a  
HIGH signal output EQ. These controls are used to increase (up to +15dB) or decrease (down to  
-30dB) the HIGH frequency output signal. Turn the knob counter-clockwise to decrease a value  
or clockwise to increase a value.  
5. SOURCE SELECTOR SWITCH -  
These are two-position switches. The switches are used to select the input source assigned to each  
channel. Each channel may only be assigned one input source at a time.  
6. CHANNEL FADER -  
Each channel fader is used to control the output level of the channel's selected input source.  
7. CUE BUTTONS -  
These buttons are used to activate a channels "CUE" mode. A red LED above the cue button will glow  
when cue mode is activated. Cue mode will send a channels incoming signal to the headphones. The  
cue level is adjusted by the CUE LEVEL ADJUSTMENT KNOB (12). Be sure the cue level is set to  
minimum before putting your headphones on. Be sure to slide the CUE MIXING SLIDER (11) to the  
cue position to hear the selected channel source.  
8. FEATHER FADER PLUS™ CROSSFADER -  
The CROSSFADER blends the output signals of any channels assigned to "Left" or "Right." When  
the fader is in the full "Left" position, the output signal of any channels assigned to "Left" will be con-  
trolled by the MASTER VOLUME LEVEL (13). The same fundamentals will apply for "Right." Sliding  
the fader from one position to another will vary the output signals of the "Left" and "Right" channels  
respectively. When the crossfader is set in the center position, the output signals of both the "Left"  
and "Right" channels will be even.  
9. “Q” START ON/OFF -  
This function works in conjunction with a compatible American Audio® "Q" series professional CD  
player. When used with a compatible "Q" series CD player, you can use the CROSSFADER (8) to  
start and stop the CD Player. The ON/OFF “Q” START switch activates this FADER “Q” START fea-  
ture. When in the ON position, the FADER “Q” START function allows the fader to return automatically  
to the CD players preset cue point by simply sliding the CROSSFADER (8) back and forth.  
For example, each time you slide the crossfader to the far left, the "Q" start function will trigger  
the play mode for any CD player connected to PLAYER CONTROL "A" (30). Play will begin at  
that unit's last set cue point. Turn the "Q" ON/OFF SWITCH to the OFF position to disengaged  
“Q” Start function and resume normal fader operation.  
10. TALKOVER SWITCH -  
While in the ON position the microphone can be used at any time, while this will not attenuate any  
other channels. When the switch is in the TALKOVER position, the microphone is hot, meaning that  
when the microphone is in use all channels attenuate -15dB except the MIC. When the microphone  
is not being spoken into all channels return to normal . In the OFF position, all signals return to their

original level and the microphone is off.  
11. CUE MIXING CONTROL -  
This functions allows you to monitor the Cue level as well as the Program (main output) level in your  
headphones. A channels Cue Level may only be monitored if the channels Cue function is selected.  
To select a channels cue function depress the CUE BUTTON (7) that is directly associated with the  
specific channel you wish to monitor. You may use the mixing function to blend both the Cue level  
and the Program level together. You can vary the output level to either hear more or less of either of  
the two levels. Sliding the Cue Mixing fader to the CUE position will allow you to hear more of the  
Cue level. Sliding the knob to the PGM position will allow you to hear more of the Program level  
(main output). You may also use the Cue Mixing Control to hear either the Cue level or the Program  
level exclusively. If the fader is in the full CUE position you will only hear the cue level, if the fader is  
in the full PGM position you will only hear the main output. This function will especially be useful for  
occasions when an external monitor is not available.  
12. CUE LEVEL VOLUME CONTROL -  
This knob is used to control the headphone volume output level.  
13. MASTER VOLUME CONTROL -  
This fader is used to control the master output level (main volume). To avoid distorted output try to  
maintain an average output signal level +4 dB. This fader will control the XLR-BALANCED (28) output  
jacks and MASTER VOLUME RCA (31) jacks.  
14. HEADPHONES JACKS -  
This jack is used to connect your headphones to the mixer. Use head phones only rated at 8 ohms to  
16 ohms. Most DJ headphones are rated at 16 ohm, these are highly recommended. Always be sure  
the CUE LEVEL VOLUME (12) is set to minimum before you put the headphones on.  
15. MIC 1 INPUT JACK -  
Combination Microphone Plug. This jack will accept a standard 1/4" male plug or a XLR 3-pin bal-  
anced male plug. The volume output level will be controlled by the MIC 1 VOLUME CONTROL KNOB  
(18).  
16. BNC JACK -  
This jack is used to supply a 12V DC signal to a gooseneck light, such as the American Audio® GNL-  
14.  
17. FADER ASSIGN SWITCH -  
This is a four position switch that assign a channel to the CROSSFADER (8). When a channel is  
assigned to the left side of the CROSSFADER (8) that channels output level will be controlled by the  
CROSSFADER (8). Sliding the CROSSFADER (8) to left position will send full volume output to the  
MASTER VOLUME LEVEL (13) and sliding the CROSSFADER (8) to right position will cut that chan-  
nels volume to MASTER VOLUME LEVEL (13). The reverse is true for the right channel fader assign  
switch.  
18. MIC 1 and MIC 2 VOLUME CONTROL KNOBS -  
These knobs are used to adjust the microphone volume output level of MIC 1 (15) and MIC 2 (38) .  
 
FRONT PANEL - CONTROLS AND FUNCTIONS CONT.  
19. MICROPHONE EQ SECTION -  
MIC BASS CONTROL - This knob is used to adjust the low frequency output of both MIC 1  
(15) and MIC 2 (38). Turning the knob in clockwise direction will increase the low  
frequencies, turning the knob in a counter-clockwise direction will decrease the low  
frequencies.  
MIC MID CONTROL - This knob is used to adjust the mid range frequency output of both  
MIC 1 (15) and MIC 2 (38). Turning the knob in clockwise direction will increase the mid  
range frequencies, turning the knob in a counter-clockwise direction will decrease the mid  
range frequencies.  
MIC TREBLE CONTROL - This knob is used to adjust the high frequency output of both MIC  
1 (15) and MIC 2 (38). Turning the knob in clockwise direction will increase the high range  
frequencies, turning the knob in a counter-clockwise direction will decrease the high range  
frequencies.  
20. SPLIT CUE -  
This button will activate the "Split Cue" function. When used with a set of stereo head phones, the  
Split Cue function assign the Cue signal the left channel of the headphones and assigns the Program  
(main output) signal to the right channel of the headphones. Essentially splitting the cue signal in half.  
Please note that this function will only work with a set of stereo headphones.  
21. MASTER LEVEL BALANCE CONTROL -  
This knob controls the balance level output of the MASTER VOLUME FADER (13). The knob has  
center lock position for precise center panning. Turning the knob to the "L" (counter-clockwise) posi-  
tion will increase the left channel output level. Turing the knob to "R" (clockwise) position will increase  
the right channel output level, while decreasing the left. To maintain a true stereo sound, level the  
balance control knob set to the 12 O'clock, or center position.  
22. PAN CONTROL -  
The balance control for each channel, or how much left and right signal is sent to the left and right  
MASTER OUT JACKS (31).  
23. ZONE LEVEL VOLUME OUTPUT CONTROL -  
This rotary knob is used to control the zone level volume. The zone level is not PFL, it is essentially a  
second master output volume with separate output volume control.  
24. ZONE LEVEL EQ SECTION -  
TREBLE CONTROL -This knob is used adjust the high frequency output of the ZONE  
LEVEL VOLUME OUTPUT (23). Turning the knob in clockwise direction will increase the high  
frequency output, turning the knob in a counter-clockwise direction will decrease the high  
frequency output.  
BASS CONTROL - This knob is used adjust the low frequency output of the ZONE LEVEL  
VOLUME OUTPUT (23). Turning the knob in clockwise direction will increase the low  
frequency output, turning the knob in a counter-clockwise direction will decrease the low  
frequency output.

ping noises. There are two convenient ground terminals located on the rear of the mixer.  
26. AC VOLTAGE SELECTOR -  
Select between 115V/50Hz or 230V/60Hz. Make sure that the selector is set to the proper voltage  
you are using.  
27. AC CONNECTION -  
This connection is used for your detachable AC power cord. Be sure to only plug your unit in to the  
recommended power supply.  
28. BALANCED XLR MASTER OUTPUTS -  
The Master Output includes a pair XLR BALANCED JACKS as well as a pair RCA UNBALANCED  
JACKS (31). The 3-pin XLR jacks send a high current balanced output signal. These jacks should be  
used when you will be driving an amp or other audio equipment with a balanced input, or whenever  
you will be running a signal line greater than 15 feet.  
29. LIGHT CONTROL OUTPUT -  
This jack provides a preset mono audio output signal. There is no way to adjust this level, however  
this level will directly reflect the output level of the CHANNEL SLIDERS (6). This buffered audio out-  
put should only be used with light controllers that can accept an external audio input signal. Great  
for Touch Panels and Chase Controllers.  
30. PLAYER CONTROL -  
These jacks are used to input 1/8" mono mini plugs from a compatible American Audio "Q" series CD  
players also featuring Fader “Q” Start. This feature is used to remote control a CD player. By moving  
the mixer crossfader (30) from left to right you can start and pause a "Q" series compact disc player.  
In other words, when the mixer crossfader is to the left, and you move it at least 20% to the right,  
any player connected to the "B" PLAYER CONTROL will begin to play. When the crossfader is to  
 
REAR PANEL - CONTROLS AND FUNCTIONS  
the right, and you move it at least 20% to the left position, any player connected to the "A" PLAYER  
CONTROL will begin to play. You can create great effects similar to scratching with this feature.  
31. RCA MASTER OUTPUTS -  
The Master Output includes a pair XLR BALANCED JACKS (28) as well as a pair RCA UNBALANCED  
JACKS. The RCA jacks send a low current unbalanced output signal. These jacks should only be  
used for shorter cable runs to signal processors or looping to another mixer. For cable runs greater  
than 15 feet use the XLR BALANCED JACKS (28).  
32. ZONE LEVEL OUTPUTS -  
The RCA jacks send a low current, unbalanced output signal. These jacks should only be used for  
shorter cable runs to signal processors or looping to another mixer.  
33. REC OUT -  
This is a low current unbalanced output source designed for various tape and CD recorders. The  
Record Out (REC OUT) level is dictated by the CHANNEL FADER LEVEL (6), it is not influenced by  
the MASTER VOLUME CONTROL (13).  
34. CHANNEL 3 - LINE 3/ LINE 4 RCA INPUT JACKS -  
Connect CD players or Tape Decks to these line level inputs. Line level musical instruments with  
stereo outputs such as Rhythm Machines or Samplers should also be connected to LINE inputs.  
Turntables should only be connected to "Phono" inputs. The red colored RCA jack represents the  
right channel input and the white represents the left channel input.
