Q-2411™  
QUICK START INSTRUCTIONS  
QUICK START: American Audio® would like to thank you for your purchase of this great audio prod-  
uct. 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-2411™ 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  
(12) 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.

1. MICROPHONE 1 - This combo jack will accept a standard 1/4 plug or XLR 3-pin balanced male  
plug. The volume output level for this microphone will be controlled by its own respective CHANNEL  
KNOB (20). Note: We recommend that you use a 500-600ohm microphone for the best sound  
quality.  
2. 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 (11) is set to level 8.  
2. Set the CHANNEL FADER (14) 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  
3. CUE BUTTON - These buttons are used to activate a channels “CUE” mode. A red LED on 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 (12). Be sure the CUE  
MIXING KNOB (13) is set to the “CUE” position to hear a selected channel source.  
4. SOURCE SELECTOR SWITCH - These switches are used to select the input source assigned to

each channel. Each channel may only be assigned one input source at a time. This switch must be in  
the “phono” position for turntable operation.  
5. 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.  
6. POWER SWITCH - This is the main power ON/OFF button. A red 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.  
7. 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.  
8. 5-BAND GRAPHIC EQUALIZER - Used to fine-tune the master output. The frequencies are as  
follows: 60Hz, 250Hz, 1KHz, 4KHz, and 16KHz. They can be adjusted by +/-10 dB.  
9. HEADPHONE 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 (12) is set  
to minimum before you put the headphones on.  
10. EQUALIZER SWITCH - This button is used to switch the equalizer on or off.  
11. 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. (see  
Channel Gain 2) 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.  
12. 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.  
13. 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 (3) function is selected. To select a channels cue function press the CUE BUTTON  
(3) 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.  
14. 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 (11).  
15. 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 (16). 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.  
16. 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.  
17. MIC 1 ON/OFF BUTTON - This button is used to turn Microphone 1 “On” or “Off”.  
18. MIC 2 ON/OFF BUTTON - This button is used to turn Microphone 2 “On” or “Off”.
