1. FEATHER FADER PLUS™ CROSSFADER - Mixes the signals of channel 1 and channel 2. When the
crossfader is set in the center position, both channels can be heard at once.
2. HAMSTER SWITCH - Changes the polarity of the Crossfader (for crabbing). Channel 1 will be activated
by the right side of the crossfader (mixing from right to left), and Channel 2 will be activated by the left
side of the crossfader (mixing from left to right).
3. CHANNEL FADER - These faders control the output level of each channel.
4a. CHANNEL 1 TRANSFORMER SWITCH (CHANGEABLE) - Used to select the input to be sent to channel
1. TRANSFORMER SWITCH may be used up/down or left/right. To change the switch, see diagram on
page 9.
4b. CHANNEL 2 TRANSFORMER SWITCH (CHANGEABLE) - Used to select the input to be sent to
channel 2. TRANSFORMER SWITCH may be used up/down or left/right. To change the switch, see
diagram on page 9.
5. PFL BUTTONS - Depressing these button sends the PFL (Pre-Fader Level) input signal to the cue level
controls (14, 15, and 16). This allows you to monitor an input signal in a pair of headphones.
Front Panel - Functions and Controls Cont.
6. TALKOVER BUTTON - When the button is depressed, all signals except the microphone level are
decreased by 15dB. A red LED will glow when the talkover function is engaged. In the OFF position
all signals remain at their standard levels.
7. MICROPHONE CONTROLS (VOLUME/TREBLE/BASS) - The DJ MIC LEVEL CONTROL controls the
microphone volume output level. The DJ MIC TREBLE CONTROL and DJ MIC BASS CONTROL are used
to adjust treble and bass levels of the DJ MICROPHONE.
8. CUT BUTTONS - These buttons cut the Treble, Mid or Bass input signal level by 100% for Channels
1 and 2. When specific Cut Button is depressed a yellow LED will glow indicating a cut of the Treble, Mid
or Bass. Depressing the Cut Button once again will disengage Cut.

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 desired 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.
Replacing the Transformer Switch
1. Disconnect the mixers main power supply
2. Using a number two Phillips screw driver, unscrew the two larger stainless steel retain screws
on the outside corners of the selector switch. These screws hold the selector switch in place.
3. Gently remove the selector switch from its seated position.
4. After removing the selector switch, disconnect the ribbon cables that attach the selector switch
to the PC board. Grasp the selector switch by its base and pull the ribbon cables by their
connectors not the actual cables. The connector are color code and only fit one way, so don't
worry about the connectors orientation.
