							INTRODUCTION: American Audio® would  like to 
thank you for your purchase of this great audio 
product. For thos e 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 famil-
iarize yourself with the ba sics of this mixer. The 
Q-Spand™ is part  of American Audio’s continuing 
evolution in au dio technology. This unit has been built and  designed to meet the needs of a typical DJ. 
We have attemp ted to provide you with the most reliable product on the market by using only compo-
nents construc ted of the  nest material.
MASTER  LEVEL - Use this leve l 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 speake rs. 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 contro ls are used to aid in distortion control. Use these 
control to preset your signal level before the crossfader. With your channel faders in the maximum posi-
tion, use the channel trim level to set an average output level of about +4dB on you master level meter.
HEADPHONES -  To  avo i d  d amag i ng  yo ur  he adphones always be sure the headph one volume level (27) 
is set to minimum before plugging them in. To avoid sever hearing damage, never put the headphone 
on without making sure the headphone level is turned down.
MAIN  MIC - The main mic conn ector uses a combo plug that allows you to connect either a 1/4” unbal-
anced 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. When feedback occurs when using the 
mic, try lowering the “low” level this may reduce the feedback. Always leave the mic level to it’s minimum 
level when not in use.
PHONO /AUX LINE LEVEL SELECTOR SWITCH (44, 47, & 50) -  This switch is used to change the 
selected input from phono to line and vice versa..The switch selectors are on the rear panel.
3D ST (16) -  SRS (Sound Retrieval System) is the leading 3D Sound technology in the\
 world. It 
retrieves the spatial information from any stereo recording and restores\
 the original three-dimensional 
sound  eld. As a result, the reproduced sound is much closer to that of a live \
performance. 
Tr u B a s s   (32) - This is a remarkable audio enhancement tech nology from SRS Labs that provides deep, 
rich bass to small speaker systems without the need for a sub-woofer. For systems with a sub-woofer, 
Tr u B a s s  c o mplements and enhances bass performance. 
WOW FEATUR E (31) - This feature dramatically impacts your audio system with increased audio 
dynamics. WOW is the latest audio technology from SRS Labs and creates extraordinary enhancement 
to the listenin g experience. Ordinary stereo presents a rather limited spatial presentation, and often lack-
luster bass (low  frequency) perfor mance. Any sound system including can deliver an audio performance 
with drastically improved image size, dynamics an d immersion when playing a signal processed with 
WOW. Th e 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.

31  Q-SPAND™                      CONTROLS AND FUNCTIONS
1. M ICROPHONE TR EBLE CONTROL - This knob is used to adjust th e treble levels of microphones 
one and two, with a maximum signal gain of 15dB or maximum signal decrease of -30dB. Turning the 
knob in a counter-clockwise direction will  decrease the amount of treble applied to the microphone 
signal, turning the knob in a clockwise direction will  increase the amount of treble applied to microphone   
signal.
2. TALKOVER  CONTROL -  When this button is depressed, all signals except the microphone level are 
decreased by 15dB. In the OFF position all signals remain at their standard levels.
3. MICROPHONE  1 COMBO JACK - Combination Microphone Jack. This jack will accept a standard 
1/4 plug or XLR 3-pi n balanced male plug. The volume output level will be controlled by the  Mic 1 
Volum e  K n ob (18) .
4. Q-START ON/O FF SWITCH - This function works in conjunction with a compatible 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 crossfader. The ON/OFF “Q START switch activates 
the FADER “Q START feature. When in the ON position, the FADER “Q START automatically returns 
the  CD player to the preset CUE POINT.

Fo r example; Assuming you have two compatible  American Audio™ CD players or a compat-
ible dual CD player connected to channels one and two. When the Fader Q Start option is 
turned on, slidin g 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 SWITCH to the OFF position to disen-
gaged “Q ”Start function and resume to a normal fader. 
						

							5. SOURCE SELECTO R SWITC H - 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 GA IN 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. Setti\
ng the gain level properly will 
ensure a clean output signal. An improper gain level adjustment will sen\
d a distorted signal throughout 
the entire audio line. To properly set the gain level control:
    1. Be sure the  Master Volume Control (26)  is set to level 8.
    2. Set the  Channel Fader (9)  to level 8.
    3. Begin play on an audio source connected to the channel you are adjust\
ing.
    4. Use the  Gain Control  to adjust an average output volume of +4 dB in the  LED Level    
        Indicator (15).
    5.  Repeat this step for all channels
7.  C H A N N E L  TR E B LE   C O NTR O L  -  This knob is used to adjust the treble levels of channels one 
through four, with a maximum signal gain of 15dB or maximum signal decrease of -30dB. Turning the 
knob in a counter-clockwise direction will  decrease the amount of treble applied to the source signal, 
turning th e knob in a clockwise direction will increase the amount of treble applied to source signal.
8. CHANNEL MIDR ANGE CONTROL - This k no b is used to ad just the midrange levels of c hannels one 
through four, with a maximum signal gain of 15dB or maximum signal decrease of -30dB. Turning the 
knob in a counter-clockwise direction will  decrease the amount of treble applied to the source signal, 
turning th e knob in a clockwise direction will increase the amount of treble applied to source signal.
9. CHANNEL VO LU M E  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 Con-
trol (26).
10 . CU E SELECTOR BUTTON -  These buttons are used to activate a channels “CUE” mode. A red LED 
next to the Cue button will glow when a channels cue mode is activated. \
Cue mode will send a channels 
incoming signal to the headphones. The cue level is adjusted by the  Cue Level Knob (27). Be sure the 
Cue Mixing Knob (25)  is turned to the “CUE” position to hear the selected channel sour\
ce.
11 .  M A STE R  O UTP UT   BALANCE CONTROL - Used to adjust how much of the signal is sent to the left 
and righ t output level. For true stereo imaging, maintain the knob in the 12 o clock position. 
12 . LEVE L INDICATORS -  The dual LED’s indicators are used to  indicate the average master output 
level. The level indicators will directly re  ect the  Master Volume  Level (26) .
13 . MAI N POWE R SWITCH - This is the main power ON/OFF button. A yellow LED beside the power 
switch will glow  indicating power is ON. Before main power is applied, be sure you have made all con-
nections to the mixer.  Also be sure your ampli  er(s) is tu ned off. Re member to avoid damaging pops, 
mixer on   rst and turned off last.
14 .  B N C JACK FOR GOOSENECK LAMP  - This jack is used to connect an American Audio 12V DC 
gooseneck lamp.
15 .  WIDTH CONTROL  - This knob is used to control the amount of SRS 3D process is applied to the

Process. SRS retrieve s the spatial information from recordings and restores the original three-dimen-
sional sound   eld. 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-dimensio nal sound. A microphone does not possess the abil-
ity to interpret the direction a sound is coming from in the same way that the human ear does. However, 
when the audio source is recorded, directional audio cues are still present in the recording. By break-
ing 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 relati ve to the direct sounds, such as  a soloist or dia-
logue. These spatial cues are restored by the use  of Head Related Transfer Functions ( H RTFs), which 
process ambient sounds vi a patented frequency response correction curves.
17.  M I C R O P H O N E   BASS CONTROL - This knob is used to adjust th e low frequency levels of micro-
phones one and two. This control allows for a maximum signal gain of 15dB or maximum signal 
decrease of -30dB. Turning the knob in a counter-clockwise direction will  decrease the amount of treble 
applied to the source signal, turning the knob in a clockwise direction will increase the amount of treble 
applied to source signal.
18 . M I C 1 VOLUME CONTROLS -  This knob controls the output volume of  Microphone 1 (3). Turning 
the knob in a clockwise direction will increase the  volume, turning the knob in counter-clockwise direc-
tion will decrease volume output.
19. M I C 2 VOLUME CONTROLS -  This knob controls the output volume of Microphone 2 (52) . Turning 
the knob in a clockwise direction will increase the  volume, turning the knob in counter-clockwise direc-
tion will decrease volume output.
20. FADE R CURVE ADJUSTMENT -  This knob is used to manipula te the crossfaders response. The 
crossfader can operate in several different modes, NORMAL CURVE, QUICK CURVE (Quick Curve 
usually used for crabbing), and a variety of slopes in  between. Turning the knob in a clockwise direction 
will make the crossfader more responsive. 
21. FADER ASSIGN SWITCH -  This is a five position switch that assign a channel to the  Crossfader 
(22) . When a channel is assigned to the left side of the  Crossfader (22) that channels output level 
will be controlled by the  Crossfader (22). Sliding the Crossfader (22)  to left position will send 
full volume output to the  Master Volume Level (26)  and sliding the  Crossfader (22)  to right 
position will cut that channels volume to  Master Volume Level (26). The reverse is true for the 
right channel fader assign switch. When this switch is set to the OFF \
position the crossfader 
will have no function.
22.   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 ou\
tput signals of channels one and 
two respectively. When the crossfader is set in the center position, the\
 output signals of both the chan-
nels one and channels two will be even.
23. CHANNEL BASS EQUALIZER -  Each of the four channels come with a BASS signal output EQ. 
These controls are used to increase (up to +15dB) or decrease (down t\
o -35dB) the LOW range output 
signal. Turn the knob counter-clockwise to decrease a value or clockwise\
 to increase a value.
24. 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 volu\
me with 
separate output volume control.

							25. 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 m\
ay only be monitored if 
the channels Cue function is selected. To select a channels cue function\
 depress the  Cue Button 
(10)  that is directly associated with the specific channel you wish to monito\
r. 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 Mi\
xing fader to the CUE position 
will allow you to hear more of the Cue level. Sliding the knob to the PG\
M  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 i\
n the full CUE position you will 
only hear the cue level, if the fader is in the full PGM position you wi\
ll only hear the main output. This 
function will especially be useful for occasions when an external monito\
r is not available.  
27. CU E LEVEL VOLUME CONTROL -  This knob is used to adjust s the headphone volume output 
level. Turn the knob in a clockwise direction to increase the headphone volume.
28. TRUE BA SS LEVEL - This knob is used to control the am ount of TRU BASS process is applied 
to th e output source signal.
29. HEADPHON E JACK - This jack is used to connect your headphones to the mixer allowing you to 
monitor the cue source. Use headphones only rated  at 8 ohms to 32 ohms. Most DJ headphones are 
rated at 16 ohm, these are highly  recommended. Always be sure the  Cue Level Volume (27)  is set to 
minimum before you put the headphones on.
30. 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 lef\
t channel of the headphones 
and the Program (main output) signal to the right channel of the headp\
hones. Essentially splitting the 
cue signal in half. This process will allow for headphones mixing. Pleas\
e note that this function will only 
work with a set of stereo headphones. 
31. WO W CONTROL  - This button is used to activate the SRS
® WOW Process. Th e WOW™ process is 
a combination of 3D Stereo Process and the TRU BASS™ Process. WOW is the latest audio technol-
ogy from SRS Labs and creates extraordinary enhancement to the listening experience. Ordinary stereo 
presents a limited sp atial 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 lis-
tener 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 
yo u may eliminate the need of a separate sub-woofer.
32. TR U BASS CONTROL  - This button is used to activate the SRS
®  (S ound Retrieval System®) TRU 
BASS™ Process. TruBas s 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 perfor mance will be enhanced substantially.  Unprecedente d 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 al l together. Be sure that the TRU BASS™ process 
will not color the midrange or create bass not present on recordings. This process will only de  ne any 
bass pres ent on a recording.

age can be toggled between 115V/50Hz or 230V/60Hz. Always be sure the selector is set to the proper 
voltage for your area before attempting to operate the unit. 
34. AC CONNECTION -  This connector is used to supply main power to the unit via the included\
 
detachable power cord. Use only the supplied, polarized AC power cord. This cord is designed to  t in 
one direction only. Do not attempt to force a cord if it does not  t, be sure the cord is being inserted 
properly.
35. BALANCED XLR MASTER OUTPUTS -  The Master Output includes a pair  XLR Balanced 
JACKS  as well as a pair  RCA Unbalanced Jacks (38) . 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 audi\
o 
equipment with a balanced input, or whenever you will be running a signa\
l line greater than 15 feet. 
Always, use these jacks whenever possible.
36. 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 o\
utput level of the  Channel Sliders 
(9) . This buffered audio output should only be used with light controllers that can a\
ccept an external 
audio input signal. Great feature for Touch Panels and Chase Controllers.
37. PLAYER CONTROL -  These jacks are used to control the “Q-Start” function between the\
 mixer and 
a compatible American Audio CD Player. Input mini plugs from CD player controller into these jacks, 
input CD 1 into jack 1 and CD 2 into jack 2 and so on.
38. RCA MASTER OUTPUTS -  The Master Output includes a pair  XLR Balanced Jacks (35) 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 process\
ors or looping to another 
mixer. For cable runs greater than 15 feet use the  XLR Balanced Jacks (35).
39. ZONE LEVEL OUTPUTS -  Use this separate output signal to drive a booth monitor or separate 
sound system. The output level for these jacks will be controlled by the  Zone Volume (24) knob. 
These 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.  REAR PANEL

recorders. The Record Out (REC OUT) level is dictated by the  Channel Fader Level (9), it is not in u-
enced by the  Master Volume Control (26).
41. CHANNEL 4: LINE 4 RCA INPUT JACKS -  These Jacks are used for line level inputs. Connect 
CD players or Tape Decks to LINE inputs. Line level musical instruments with stereo out\
puts 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. Input volume will be controlled by ch\
annel four  Channel Fader (9). 
The channel  Source Selector Switch (5)  must be in the Line 4 position, to monitor any source con-
nected to these jacks.
42. CHANNEL 3: LINE 3 RCA INPUT JACKS -  These Jacks are used for line level inputs. Connect 
CD players or Tape Decks to LINE inputs. Line level musical instruments with stereo out\
puts 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
