DX5R™ Quick start instructions
American Audio® would like to thank for your purchase of this great product. For those of you that are
to 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 basic understanding of the unit. The DX5RTM is part of American Audio’s continuing evolution in audio technology. This
unit has been built and designed with the typical DJ in mind, by DJ’s. We have attempted to provide
you with the most reliable product on the market by using only components made from quality products.
.
MASTER LEVEL (8) - Use this level control to set your 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.
HEADPHONES (25) - To avoid sever hearing damage, always be sure the headphone level is set to
minimum before plugging them in. Never put the headphone on without making sure the headphone
level is turned down.
MICROPHONE 1 (1) - The main mic connector uses a 1/4” jack unbalanced connector on the rear
of the unit or XLR balanced connection on the face of the unit. Both microphone connection marks
as MIC 1 are controlled by the MIC 1 VOLUME knob. Always leave the mic level to it’s minimum level
when not in use.
.
.
.
.
.
BALANCED XLR OUTPUTS (27) - The Master Output includes a pair XLR Balanced JACKS as well
as a pair RCA UNBALANCED JACKS (19). 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 audio equipment with a
.
,
balanced input, or whenever you will be running a signal line greater than 15 feet. Always, use these
jacks whenever possible.
.
FADER ASSIGN SWITCH (19) - This is a five position switch that assigns a channel to the CROSSFADER (18). When a channel is assigned to the left side of the CROSSFADER (18) that channels
output level is routed to and controlled by the CROSSFADER (18). Sliding the CROSSFADER (18) to
.
left position will send the volume output of the assigned channel to the MASTER VOLUME LEVEL (8),
siding the CROSSFADER (18) to right position will cut that channels volume to MASTER VOLUME
LEVEL (8). The reverse is true for the right Rotary Channel Gain assign switch. When the assign switch
is set to the “OFF” position the crossfader will have no function.
.
BOOTH LEVEL (BOOTH LEVEL VOLUME CONTROL) (22) - This rotary knob is used to control the
output volume to any source connect to the BOOTH OUTPUT JACKS (34) on the rear of the unit. Be
,
sure this volume control is always set to zero before turning the unit on and off.

1. MIC 1 ON/OFF - This button is used to turn the microphone signal on and off.
2. MIC 1 (MICROPHONE 1 INPUT) - This jack accepts a standard XLR 3-pin balanced male plug.
The volume output level for this microphone is controlled by the MIC 1 VOLUME KNOB (1).
3. MIC 1 VOLUME (MICROPHONE 1 VOLUME LEVEL) - This rotary knob is used to control the
volume output level for any microphone connected to the MIC 1 INPUT JACKS (2 or 31) . Turning the
knob in a clockwise direction will increase volume output.
4. CHANNEL SOURCE SELECTOR SWITCH (TRANSFORMER 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. For all other
input devices such as CD players and tape decks this switch must be in the “line” position.
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 the gain level control:
1. Be sure the MASTER VOLUME CONTROL (8) is set to level 8.
2. Set the ROTARY CHANNEL GAIN (6) 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 in the CHANNEL LED
LEVEL INDICATOR (7).
5. Repeat this step for all channels.
6. ROTARY CHANNEL GAIN - The Rotary Channel Gains are used to control the output signal of any
source assigned to its particular channel. However, the master volume for all channels is controlled by
the MASTER VOLUME CONTROL (8).
7. CHANNEL VOLUME LEVEL INDICATORS - The LED’s 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.
8. MASTER VOLUME CONTROL - This rotary knob is used to control the master output level (volume).
To avoid distorted output maintain an average output signal level of +4 dB. Be sure this volume control
is always set to zero before turning the unit on.
9. MASTER OUTPUT 4-BAND EQ - The DX5R includes a 4-band master output EQ. The adjustable
EQ bands are bass, mid low, mid high, treble. These knobs are used to increase (+20dB) or decrease
(-30dB) the band width of each frequency applied to the output source signal. Turning the knobs in a
counter-clockwise direction to decrease a value or clockwise to increase a value.
10. MASTER OUTPUT INDICATORS - The dual LED’s indicators are used to indicate the master
output volume level and directly reflect the output signal. To avoid signal distortion maintain an average
signal output of +4dB.
11. SUBWOOFER OUTLEVEL - This knob is used to control a completely independent subwoofer
output level. The output signal is sent through the mono SUBWOOFER OUTPUT JACK (33) on the rear
of the unit.
12. MAIN POWER SWITCH - This is the main power ON/OFF button. A red LED below the power
switch will glow indicating main power is on. Before main power is applied, be sure you have made all
connections to the mixer. Also be sure your amplifier(s) is(are) turned off. Remember to avoid damaging pops to your speakers, the mixer is turned on first and turned off last.
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 (23) will
also work in conjunction with function. Please note that this function will only work with a set of stereo
headphones.
14. MICROPHONE EQ - These controls are used to adjust the microphone treble level, midrange, and
bass levels. Each microphone input has a separate channel EQ.
MICROPHONE TREBLE CONTROL - This knob is used to adjust the treble levels of the Micro
phone 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.
MICROPHONE BASS CONTROL - This knob is used to adjust the low frequency levels of the
microphone 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 bass applied
to the microphone signal, turning the knob in a clockwise direction will increase the amount
bass applied to the microphone signal.
15. MIC 2 ON/OFF - This button is used to turn the microphone 2 signal on and off.
16. MIC 2 VOLUME (MICROPHONE 2 VOLUME LEVEL) - This rotary knob is used to control the
volume output level for any microphone connected to the MIC 2 INPUT JACK (43). Turning the knob in
a clockwise direction will increase volume output.
17. CUE SELECTOR SWITCH - These buttons are used to activate a channels “CUE” mode. A red

LED next to the Cue Selector Button will glow when a channels cue mode is activated. The Cue function sends a channels incoming signal to the headphones. The cue volume level is adjusted by the CUE
LEVEL KNOB (24). Be sure the CUE MIXING KNOB (23) is in the “CUE” position to hear a selected
channels source.
18. FEATHER FADER PLUS CROSSFADER - This fader is used to blend the output signals of any two
channels together. When the fader is in the full left position, the output signal of any channel assigned
to the left side of the fader will be controlled by the master volume level. The same fundamentals will
apply for any channel assigned to the right side of the fader. Sliding the fader from left position to the
right will vary the output signals of any two channels respectively. When the crossfader is set in the
center position, the output signals of both channels will be even.
19. FADER ASSIGN SWITCH - This is a five position switch that assigns a channel to the CROSSFADER (12). When a channel is assigned to the left side of the CROSSFADER (18) that channels output
level is routed to and controlled by the CROSSFADER (18). Sliding the CROSSFADER (18) to left position will send the volume output of the assigned channel to the MASTER VOLUME LEVEL (8), siding
the CROSSFADER (18) to right position will cut that channels volume to MASTER VOLUME LEVEL (8).
The reverse is true for the right Rotary Channel Gain assign switch. When the assign switch is set to
the “OFF” position the crossfader will have no function.
20. 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
crossfader to start and stop a CD Player with the slide of the mixer’s CROSSFADER (18). 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 AudioTM CD players or a com patible 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

DX5R™ Cleaning
Due to fog residue, smoke, and dust, cleaning the mixer should be carried out periodically to optimize
light output.
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. Clean should be carried out every 30-60 days.
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).
DX5R™ 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 retaining
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 reassemble in reverse order.
