1. FEATHER FADER PLUS™ CROSSFADER - Blends the output signals of any channels assigned to "X"  
or "Y." When the fader is in the full "X" position, the output signal of any channels assigned to "X" will be  
controlled by the master volume level. The same fundamentals will apply for "Y." Sliding the fader from  
one position to another will vary the output signals of the "X" and "Y" channels respectively. When the  
crossfader is set in the center position, the output signals of both the "X" and "Y" channels will be even.  
2. HEADPHONES JACKS - These jacks are used to connect your headphones to the mixer. Use head-  
phones only rated at 8 ohms to 16 ohms. Most DJ headphones are rated at 16 ohm, these are highly  
recommended. Two different headphone jacks are conveniently located on the mixer, one on the face and  
one on the front side panel. Always be sure the Cue Level Volume (6) is set to minimum before you  
put the headphones on.  
3. FADER ASSIGN BUTTONS - These buttons are used to assign a channel to the crossfader. When a  
channel is assigned to "X," the left side (X-side) of the crossfader will control that channels output level.  
The "Y" assign works in the same fashion. When a channel is assigned to neither "X" nor "Y" the output  
volume will only be controlled by the channel's fader level. These button also function as a "TRANS  
EFFECT" A Trans Effect is an effect similar to cutting the output signal with your transformer switches.  
 
FRONT PANEL - CONTROLS AND FUNCTIONS CONT.  
This is an effect used heavily by scratchers and performer DJ's. The mixer simulates this effect when you  
hold down the X and Y fader buttons. The speed of the transform is preset and will only effect any channel  
assigned to the fader assign button being depressed.  
4. CHANNEL FADER - These faders are used to control the output signal of any source assigned to its  
particular channel.  
5. SPLIT CUE - This button will activate the "Split Cue" function. When used with a set of stereo head-  
phones, the Split Cue function assign the Cue signal the left channel of the headphones and assigns the  
Program (main output) signal to the right channel of the headphones. Essentially splitting the cue signal  
in half. Please note that this function will only work with a set of stereo headphones.  
6. CUE LEVEL VOLUME CONTROL - This knob is used to adjusts the headphone output level.  
7. 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 function is selected. To selceted a channels cue function depress the Cue Button (22) 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. Turning the Cue Mixing knob to the CUE position (counter-clockwise)  
will allow you to hear more of the Cue level. Turning the knob to the PGM (clockwise) 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 knob is in the full CUE position you will only  
hear the cue level, if the knob is in the full PGM position you will only hear the main output. This function  
will esspecially be useful for occasions when an external monitor is not available.  
8. CROSSFADER CURVE ADJUSTMENT - This adjustment allows you to adjust the geometry or "shape"  
of the crossfader response curve. The response curve can be adjusted from smooth to harsh (Instant).  
The smooth adjustment - full counter clockwise - allows for a long running crossfade. This adjustment  
will usually be used for normal DJing. The harsh adjustment - full clockwise adjustment - allows for a  
short crossfade. This adjustment will usually be used for scratching and cut effects.  
9. TALKOVER BUTTON - When this button is depressed, all signals except the microphone level are  
decreased by 15dB. A red indicator LED will glow when the talkover function is engaged. In the OFF  
position all signals remain at their standard levels.  
10. MIC 3 INPUT JACK - Combination Microphone Plug. This jack will accept a standard 1/4 plug or XLR  
3-pin balanced male plug. The volume output level will be controlled by the Channel 3 Fader (4).  
11. CHANNEL GAIN 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. Setting the gain level properly will ensure a  
clean output signal. To properly set the gain level controls:  
1. Be sure the Master Volume Control (16) is set to minimum (zero output).  
2. Set the Channel Fader (4) to level 7.  
3. Begin play on an audio source connected to the channel you are adjusting.  
4. Be sure the LED Level Indicator Function Switch (15) is set to the PFL/MASTER position.  
5. Turn the CUE (22) function on for the channel you are adjusting.  
6. Use the GAIN Control to adjust an average output volume of +4 dB in the LED Level Indicator (14).  
12. CUT BUTTONS - These buttons are used cut out the Treble, Mid or Bass frequencies of the incoming  
audio signal. When these buttons are depressed the selected frequency level is cut by 100%. When a  
Cut Button is depressed a LED located directly above the specific button will glow indicating the  
cut function has been activated. Depressing the Cut Button once again will disengage Cut function.  
13. CHANNEL EQUALIZER "ROTARY KILLS" - BASS/MID/TREBLE CONTROL - Each of the three  
channels come with a signal output EQ. These controls are used to increase or decrease the LOW's,  
MIDs, and HIs of the output signal. The Q-MX2 features "Rotary Kills" with a -30dB to +20dB gain control.  
 
FRONT PANEL - CONTROLS AND FUNCTIONS CONT.  
Turn the knob counter-clockwise to decrease a value or clockwise to increase a value.  
14. LED LEVEL INDICATORS - The dual LED's indicators along the top of unit are used to detail  
either the master output level or a combination of the master output level and the cue PFL level. The  
position of the LED Level Indicator Function Switch (15) will determine the LED Level Indicator's display  
mode. In the "MASTER" (down) position the meter will detail the out level of the left and right channels.  
In the "PFL/ MASTER" (up) position one side of the meter will detail the master output volume level and  
the other section of the meter will detail the CUE level PFL (pre fader level).  
Please Note: PFL stands for Pre Fader Level. This is the input channel signal level you will  
hear in your headphones.  
15. POWER SWITCH - This is the main power ON/OFF button. A yellow LED above the power switch will glow  
to indicating power is ON. Be fore you turn the power on be sure you have made all connections to the  
mixer. Also be sure you amplifier are tuned off. Remember mixer on first and turned off last.  
16. LED LEVEL INDICATOR FUNC TION SWITCH - The position of the LED Level Indicator Function  
Switch (15) will determine the LED Level Indicator's display mode. In the "MASTER" (down) position the  
meter will detail the out level of the left and right channels. In the "PFL/ MASTER" (up) position one  
side of the meter will detail the master output volume level and the other section of the meter will detail  
the CUE level PFL (pre fader level).  
17. MASTER VOLUM E CONTROL - This rotary knob is used to control the master output level (volume). To  
avoid distorted output try to maintain an average output signal level +4 dB.  
18. MASTER VOLUM E BALANCE CONTROL - This rotary knob is used to control the master output balance  
level. Turning the knob to the "L" (counter-clockwise) position will increase the left channel output level.  
Turing the knob to "R" (clockwise) position will increase the right channel output level, while decreasing the  
left. To maintain a true stereo sound, level the balance control knob set to the 12 O'clock, or center  
position.  
19. BOOTH LEVEL VOLUM E CONTROL - This rotary knob is used to control the booth level volume. The  
booth level is not PFL, it is essentially a second master output volume with separate output volume control.  
20. ON/OFF Q START- This function works in conjunction with a compatible American DJ "Q" Start CD  
player. When used with a compatible CD player, you can use the crossfader to start and stop the CD  
Player with the slide of the fader. The ON/OFF QSTART switch activates this FADER QSTART feature.  
When in the ON position, the FADER QSTART allows the fader to return automatically to preset digital  
CUE POINTS on your compatible American DJ CD Player.  
For example, each time you slide the crossfader to far left the CD Player will be triggered to play the  
song from the beginning of the preset CUE POINT. Refer to your American DJ CD Player User Manual  
for setting CUE POINTS. Turn the ON/OFF SWITCH to the OFF position to disengaged QStart  
function and resume to a normal fader.  
21. SOURCE SELECTOR SWITCH - These are 3-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.  
22. CUE BUTTONS - These buttons are used to activates a channels "CUE" mode. A red LED above the  
cue button will glow when cue mode is activated. Cue mode will send a channels incoming signal to  
the headphones. The cue level is adjusted by the Cue Level Adjustment knob (6). Be sure the cue level  
is set to minimum before putting your headphones on. Be sure to turn the Cue Mixing Knob (7) to the cue  
position to hear the selected channel source.  
23.AUTOMATIC BPM (Beat Per a Minute) COUNTER BUTTONS - This sophisticated counter automatically  
calculates the BPM of any audio source. The meter on the "X" side will display the avaerage BPM's of any  
Channel (1, 2, or 3) assigned to "X" by the Fader Assign Buttons (3). The meter on the "Y" side will  
display the avaerage BPM's of any Channel (1, 2, or 3) assigned to "Y" by the Fader Assign Buttons (3).

set to the proper voltage you are using.  
23. BALANCED XLR MAIN OUTPUTS - The Master Output includes a pair XLR Balanced Jacks as well as  
a pair RCA Unbalanced Jacks (30). 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 10 feet.  
24. LIGHT CONTROL - This jack provides a preset mono audio signal output. There is no way to adjust this  
level, however this level will directly reflect the output level of the Channel Sliders (4). This buffered  
audio output should only be used for light controllers that can accept an external audio input. Great for  
Touch Panels and Chase Controllers.  
25. PLAYER CONTROL - Channel 1, 2, and 3 external FADER “Q” START CONTROL. These jacks are used  
to input 1/8" mono mini plugs from a compatible American DJ "Q" series CD players also featuring Fader  
QStart. This feature is used to remote control a CD player. By moving the mixer fader from left to right  
you can start and pause a compact disc player. In other words, when the mixer crossfader is to the left (X  
position), and you move it at least 20% to the right (Y position), any player connected to the Y-channel will  
begin to play. When the crossfader is to the right (Y position), and you move it at least 20% to the left (X  
position, any player connected to the X-channel will begin to play. You can create great effects similar  
to scratching with this feature.  
26. MIC 2 INPUT JACK - This jack is used to a connect a microphone to the mixer. Connect you mic to MIC  
2 via 1/4 inch (6.3mm) jack. The signals will be controlled by Channel 2 (4). BASS, MID, and TREBLE can  
be adjusted by the Channel EQ (13).  
27. MIC 1 INPUT JACK - This jack is used to a connect a microphone to the mixer. Connect you mic to MIC  
1 via 1/4 inch (6.3mm) jack. The signals will be controlled by Channel 1 (4). BASS, MID, and TREBLE can  
be adjusted by the Channel EQ (13).

SET-UP INSTRUCTIONS  
INPUTS/OUTPUTS  
The MX-1 allows you two types of output connectors Balanced XLR (25) and Unbalanced RCA (32, 33, and  
34). Use these connection to connect the output signal from a mixer, cross-over or EQ to your MX-1 mixer. A  
balanced connection is recommended for cable runs longer that 10ft. When constructing your own XLR cables  
follow the pin conguration describe below for proper connections. For cable runs shorter than 10Ft. you may  
choose the RCA unbalanced output option. The unbalanced output option may be more convenient for most  
users due to the abundant supply of prefabricated cables on the market.  
All the input options on the mixer are unbalanced RCA's. For best results do not use cable run longer than 10ft  
for any incoming audio source, longer cable runs will result in inferior sound quality.
