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 (20) will
also work in conjunction with function. Please note that this function will only work with a set of stereo
headphones.
20. 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 (12) function is selected. To select a channels cue function press the Cue button
(12) 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
(left) will allow you to hear more of the Cue level. Turning 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 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 is especially useful when mixing without an monitor.
21. 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 le Vel VoluM e (18) is set
to minimum before you put the headphones on.
22. taLkover controL - This function decreases all signal output except the microphone signal.
The amount of decrease is preset to -14d b and is not user selectable.
23. 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 (14).
24. Mic 2 voLuMe controL - This fader controls the output volume of MiCrophone 2 (2).
however, master volume is controlled by the MASTER VOLUME CONTROL (14).\
25. Mic 1 voLuMe controL - This fader controls the output volume of MiCrophone 1 (1).
however, master volume is controlled by the Master VoluMe Control (14).
26. Fader assiGn sWitch - This switch assigns a channel to the Crossfader (16). When a
channel is assigned to the left side of the Crossfader (16) that channels output level is routed to
and controlled by the Crossfader (16). Sliding the Crossfader (16) to left position will send the
volume output of the assigned channel to the Master VoluMe leVel (14), siding the Crossfader
(16) to right position will cut that channels volume to Master VoluMe leVel (14). The reverse is
true for the right channel fader assign switch. When the assign switch is set to the "OFF" position the
crossfader will have no function.
27. Mic 1 on/o FF Button - This switches MIC 1 On and Off.
M ic 2 on/o FF Button - This switches MIC 2 On and Off.
28. MiCROPhONE 1 & 2 TREbLE CONTROL - This knob is used to adjust the treble levels of the
Microphone with a maximum signal gain of 12db or maximum signal decrease of -12db. 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 micro-
phone signal.

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). 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 o\ ther 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 connec tors orientation. 5. Connect the new crossfader to the ribbon cable and replace in reverse order.
