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 don't have the time 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-SPAND PRO 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 you master  
level meter.  
HEADPHONES - To avoid damaging your headphones always be sure the headphone volume level  
(31) 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.

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.  
7. CHANNEL EQ SECTION -  
CHANNEL TREBLE CONTROL - This knob is used to adjust the treble levels of a channel  
allowing for a maximum treble gain of +12dB or maximum decrease of -30dB. Turning the knob in a  
counter-clockwise direction will decrease the amount of treble applied to a channel signal, turning the  
knob in a clockwise direction will increase the amount of treble applied to a channel signal.  
CHANNEL MIDRANGE CONTROL - This knob is used to adjust the midrange levels of a chan-  
nel allowing for a maximum midrange gain of +12dB or maximum decrease of -30dB. Turning the knob  
in a counter-clockwise direction will decrease the amount of midrange applied to a channel signal,  
turning the knob in a clockwise direction will increase the amount of midrange applied to a channel  
signal.  
CHANNEL BASS CONTROL - This knob is used to adjust the low frequency levels of a channel  
allowing for a maximum bass gain of +12dB or maximum signal decrease of -30dB. Turning the knob  
in a counter-clockwise direction will decrease the amount of bass applied to a channel signal, turning  
the knob in a clockwise direction will increase the amount of bass applied to a channel signal.  
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 INDICATORS - The dual MASTER LEVEL LED indicators are used to  
detail the master fader output level. The meters will detail the output level of both the left and right  
channels.  
10. MASTER OUTPUT BALANCE CONTROL - This knob is used to control the pan, adjust how much

of the signal is sent to the left and right output level. For true stereo imaging, maintain the knob in the  
12 o’ clock position.  
11. BNC JACK - This jack is used to supply a 12V DC signal to a gooseneck light, such as the  
American Audio® GNL-14.  
12. POWER SWITCH - This is the main power ON/OFF button. A blue LED next to 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.  
13. WIDTH CONTROL - This knob is used to control the amount of SRS 3D process is applied to the  
output source signal.  
14. 3D ST CONTROL - This button is used to activate the SRS® (Sound Retrieval System®) 3D Stereo  
Process. SRS retrieves the spatial information from recordings and restores the original three-dimen-  
sional sound field. As a result, the reproduced sound is much closer to a live performance. Like live  
performances, SRS has no critical listening position (sweet spot). Listeners can move around the room  
and continue to be immersed in full three-dimensional sound. A microphone does not possess the  
ability to interpret the direction a sound is coming from in the same way that the human ear does. How-  
ever, when the audio source is recorded, directional audio cues are still present in the recording. By  
breaking down the stereo signal into its various signal components, it is possible to isolate and restore  
these spatial cues and place them in the proper space relative to the direct sounds, such as a soloist  
or dialogue. These spatial cues are restored by the use of Head Related Transfer Functions (HRTFs),  
which process ambient sounds via patented frequency response correction curves.  
15. TRU BASS CONTROL - This button is used to activate the SRS® (Sound Retrieval System®) TRU  
BASS™ Process. TruBass circuity actively monitors the low-frequency content of an audio signal and  
optimizes the frequency and amplitude spectrum of the output signal to enhance bass perception.  
Whether you are limited by space, cost or implementation, for bass previously believed impossible.  
This process creates deep, rich bass in headphones and speaker systems that have poor or little bass  
response. Sub-woofer performance will be enhanced substantially. Unprecedented bass response will  
virtually eliminates the need for large speakers to create low frequency fundamental tones and will in  
several case eliminate the need for a sub-woofer all together. Be sure that the TRU BASS™ process  
will not color the midrange or create bass not present on recordings. This process will only define any  
bass present on a recording.  
16. TRUE BASS LEVEL - This knob is used to control the amount of "TRU BASS" process is applied  
to the output source signal.  
17. WOW CONTROL - This button is used to activate the SRS® WOW Process created by SRS Labs.  
The WOW™ process is a combination of 3D Stereo Process and the TRU BASS™ Process. WOW cre-  
ates extraordinary enhancement to the listening experience. Ordinary stereo presents a limited spatial  
presentation, and often lack-luster bass (low frequency) performance. Any sound system can deliver  
an audio performance with drastically improved image size, dynamics and immersion when playing a  
signal processed with WOW. Because the WOW™ effect combines the 3D Stereo™ Process and the  
TRU BASS™ Process, the processing of the spatial cues surrounds the listener with a holographic  
representation of the performance. In addition bass becomes deep, rich and controlled through means  
that don’t require a speaker with a large woofer or cabinet size. In essence you may eliminate the need  
of a separate sub-woofer.  
18. AUX 4 INPUT JACK - This Aux input is for the use of a Mp3 player, or XM or Sirius satellite radio.  
Input volume will be controlled by the channel four fader.

rated at 16 ohm, these are highly recommended. Always be sure the CUE LEVEL VOLUME (23) is set  
to minimum before you put the headphones on.  
20. 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 out-  
put volume control.  
21. SPLIT CUE - This button will activate the "Split Cue" function. When used with a set of stereo  
headphones, the Split Cue function will assign the Cue signal to the left channel of the headphones  
and the Program (main output) signal to the right channel of the headphones. Essentially splitting the  
cue signal in half. This process will allow for headphones mixing. The CUE MIXING CONTROL (24) will  
also work in conjunction with function. Please note that this function will only work with a set of stereo  
headphones.  
22. MASTER VOLUME CONTROL - This slider is used to control the master output level (main  
volume). To avoid distorted output try to maintain an average output signal level no greater than +4  
dB. To avoid speaker damage that may be caused by excessive volume, be sure this slider is always  
set to zero (completely down) before turning the unit on.  
23. CUE LEVEL VOLUME CONTROL - This knob is used to adjusts the headphone volume output  
level. Turn the knob in a clockwise direction to increase the headphone volume.  
24. 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 (27) function is selected. To select a channels cue function press the CUE BUTTON  
(27) 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 posi-  
tion (left) will allow you to hear more of the Cue level. Sliding the knob to the PGM position (right) 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 is especially useful when mixing without an monitor.  
25. CHANNEL VOLUME FADER - These faders are used to control the output signal of any source  
assigned to its particular channel. However, master volume is controlled by the MASTER VOLUME  
CONTROL (22).  
26. FADER ASSIGN SWITCH - This is a five position switch that assigns a channel to the CROSS-  
FADER (28). When a channel is assigned to the left side of the CROSSFADER (28) that channels  
output level is routed to and controlled by the CROSSFADER (28). Sliding the CROSSFADER (28) to  
left position will send the volume output of the assigned channel to the MASTER VOLUME LEVEL (22),  
siding the CROSSFADER (28) to right position will cut that channels volume to MASTER VOLUME  
LEVEL (22). The reverse is true for the right channel fader assign switch. When the assign switch is set  
to the "OFF" position the crossfader will have no function.  
27. CUE BUTTON - These buttons are used to activate a channels “CUE” mode. A red LED around  
the Cue button will glow when a channels cue mode is activated. The Cue function sends a channels  
incoming signal to the headphones. The cue level is adjusted by the CUE LEVEL KNOB (23). Be sure  
the CUE MIXING KNOB (24) is set to the “CUE” position to hear a selected channel source.

28. FEATHER FADER PLUS CROSSFADER - This fader is used to blend the output signals of chan-  
nels one and two together. When the fader is in the full left position (channel 1), the output signal of  
channel one will be controlled by the master volume level. The same fundamentals will apply for chan-  
nel two. Sliding the fader from one position to another will vary the output signals of channels one  
and two respectively. When the crossfader is set in the center position, the output signals of both the  
channels one and channels two will be even.  
29. CROSSFADER CURVE ADJUSTMENT - This rotary knob is used to change the way the cross-  
fader will operate. The crossfader can operate in different modes, “NORMAL CURVE”, “QUICK CURVE”  
or any variation of the two. (Quick Curve usually used for scratching).  
30. MIC 2 VOLUME CONTROL - This knob controls the output volume of MICROPHONE 2 (34).  
However, master volume is controlled by the MASTER VOLUME CONTROL (22).  
31. MIC 1 VOLUME CONTROL - This knob controls the output volume of MICROPHONE 1 (3).  
However, master volume is controlled by the MASTER VOLUME CONTROL (22).

CLEANING  
Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to residue  
build up.  
1. Use normal glass cleaner and a soft cloth to wipe down the outside casing.  
2. Use a cleaner specially designed for electronics to spray in and around the knobs and switch.  
This will reduce small particle built up that can effect the proper operation of the mixer.  
3. Cleaning should be carried out every 30-60 days to prevent heavy built up.  
4. Always be sure to dry all parts completely before plugging the mixer in.  
Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue,  
dust, dew).  
Q-SPAND PRO  
CROSSFADER REPLACEMENT  
The crossfader is “Hot Swapable” which means it may be replaced at any time, even when power is  
applied. Only replace with American Audio Part Feather Fader Plus. Replacing with any other model  
fader may seriously damage your mixer.  
Replacing the Crossfader:  
1. Disconnect the mixers main power supply  
2. Using a number two Phillips screw driver, unscrew the each of the stainless steel retain screws  
that hold the crossfader in place.  
3. Gently remove the crossfader from its seated position. You may need to wiggle the crossfader  
slightly to remove it.  
4. After removing the crossfader, disconnect the ribbon cable that attaches the crossfader to the  
PC board. Grasp the crossfader by its base and pull the ribbon cable by its connector not the  
actual cables. The connector is designed to only fit one way, so don’t worry about the connec-  
tors orientation.  
5. Connect the new crossfader to the ribbon cable and replace in reverse order.
