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.

2. TALKOVER CONTROL - This function all decreases all signal output except the microphone signal.
The amount of decreased is controlled by the TALKOVER LEVEL (4). When the switch is in the “Auto
Mute” position talk over will automatically engage when the when the mixer receives a signal. MIC 1
has a “Talk Over” position that decreases signal output regardless of an incoming microphone signal.
In the OFF position all signals remain at their standard levels.
3. MICROPHONE VOLUME CONTROLS -
MIC 1 VOLUME CONTROLS - This slider controls the output volume of MICROPHONE 1 (3).
However, master volume is controlled by the MASTER VOLUME CONTROL (26).
MIC 2 VOLUME CONTROLS - This slider controls the output volume of MICROPHONE 2 (3).
However, master volume is controlled by the
4. TALKOVER LEVEL - This knob is used to adjust the amount general volume will be decreased
when the TALKOVER (2) function is engaged. A maximum of -15dB can be applied to the “Talkover.”
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

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.
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.

Typical Balanced Output Set-up
This image details a typical stereo output layout. Note the use of the Balanced XLR Jacks on both the
mixer and the amplifier. Always use the balanced output jacks whenever possible.The balanced output
jacks should always be used for cable runs in excess of 15 feet.
Using the balanced jacks will ensure a clean signal through out the entire audio system.

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).

CROSS FADER 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 connectors
orientation.
5. Connect the new crossfader to the ribbon cable and replace in reverse order.
