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 Commander Plus™ 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 constructed 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 maximum posi-  
tion, 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 (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 connector 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 (31) - This switch is used to change the selected input  
from phono to line and vice versa. The switch selectors are on the rear panel.

5. ASSIGN SWITCH - This push button switch is used to turn the CROSSFADER (9) function on and  
off.  
6. FADER ASSIGN SWITCH - This is a four position switch that assigns a channel to the CROSS-  
FADER (9). When a channel is assigned to the left side of the CROSSFADER (9) that channels output  
level is routed to and controlled by the CROSSFADER (9). Sliding the CROSSFADER (9) to left posi-  
tion will send full the assigned channels volume output to the MASTER VOLUME LEVEL (26) and slid-  
ing the CROSSFADER (9) 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 ASSIGN SWITCH (5) is set to  
the "OFF" position the crossfader will have no function.  
7. Q-START ON/OFF SWITCH - 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 cross-  
fader to start and stop a CD Player with the slide of the mixer’s CROSSFADER (9). 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.  
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 SWITCH to the OFF  
position to disengaged “Q” Start function and resume to a normal fader.  
8. PFL (CUE 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. The Cue function  
sends a channels incoming signal to the headphones. The cue level is adjusted by the CUE LEVEL  
KNOB (14). Be sure the CUE MIXING SLIDER (12) is set to the “CUE” position to hear a selected chan-  
nel source.  
9. 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

nels one and channels two will be even.  
10. 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 (26).  
11. BEAT INDICATOR - The beat indicator LED’s flash at every bass beat of the respective source.  
This function is used to visually reference a tracks BPMs. This function works in conjunction with the  
CROSSFADER (9), if the CROSSFADER (9) is not activated the beat indicator will not function. The  
beat indicators directly refer to any signal source assigned to the CROSSFADER (9). Use the BPM’s  
indicator to beat sync to tracks together, as soon as the LEDs blink synchronously, the speed of the  
two sources is synchronized.  
12. 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 PFL (8) function is selected. To select a channels cue function press the PFL BUTTON (8)  
that is directly associated with the specific channel you wish to monitor. You may use the mixing func-  
tion 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 (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.  
13. 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 (12) will  
also work in conjunction with function. Please note that this function will only work with a set of stereo  
headphones.
