Blue Power LED
The blue power LED will illuminate when the mixer has been connected to a power source and switched to
the "on" position (See Section 9 "Inputs and Outputs.")
6. Crossfader Controls
Crossfader with Tracking Light System
This slide fader blends between CH-1 and CH-2. Its action can be fine-tuned using the "Slope" control
switch or it can be reversed or deactivated by the "Direction" switch. A red light glows on either the right,
left or both sides for the Crossfader indicating only the position of the Crossfader, not the amount of
signal being sent to the master output.
"Slope" (Crossfader Curve Style Control)
The position of this switch determines where the startup level of CH-1 and CH-2 lie on the crossfader
(with respect to "Direction.") When switched to the left, the Crossfader will gradually fade the channel in
to the master output signal as it is engaged. When switched to the right, a very sharp fade of the
channel will occur immediately when the fader is engaged.
"Direction" (Crossfader Assignment Reverse and Deactivation Control)
The position of this switch can reverse the assignment of CH-1 and CH-2 or deactivate the Crossfader. In
the left switch setting ("Normal",) CH-1 is assigned to the left side of the Crossfader and CH-2 is assigned
to the right side of the crossfader. In the right switch setting, the assignment of CH-1 and CH-2 are
reversed on the Crossfader. In the center position, the Crossfader is deactivated.

9. Inputs and Outputs
CH-1 and CH-2 Phono/Line Stereo Inputs
Each channel has a selectable phono level input (phonograph level/line level) and a line level input. The
line level input is used to connect CD players and other line level devices. When connecting a turntable to
the phono input, the switch must be set to "PHONO" instead of "AUX." When this switch is set to "AUX",
you can connect a line level device to the mixer (CD player, etc.) Please note that many turntables need
to be grounded to the mixer with a ground wire to prevent hum and excessive noise (see "GND.") It is
also recommended that the mixer be turned off before connecting and disconnecting any sources to the
inputs of the mixer.
WARNING: The Input Level Switch on the rear panel of the mixer must be set to "AUX" when connecting
line level devices. Failure to do so will result to damage in the mixer.
"Master" (Main Stereo Output)
This RCA output is for connecting an external device such as a PA system, powered monitors or a home
stereo. The level of the master stereo output signal increases as the "master" volume control is increased.
"Zone" (Auxiliary Stereo Output)
This RCA output is for connecting a secondary external device such as a booth monitor or second stereo
output. The level of the booth output signal will increase as the "Booth" volume control is increased.
"Rec" (Recording Level Stereo Output)
This RCA output is for connecting an external recording device such as a CD Recorder, MD Recorder or a
Tape Deck. The level of this signal is not affected by "master" volume or "booth" adjustments but is
affected by all other controls.
"GND" (Grounding Lug)
This screw connector should be used to secure any devices connected to the mixer that need to be
grounded. Most turntables that are connected to the mixer will need to have a ground wire that is
designed to connect to the mixer to eliminate hum and noise.
"Player A/B" (Fader Start Eighth Inch Terminals)
These two eighth inch terminals allow Fader/Remote Start Compatible devices (Numark CD Players) to be
connected to the unit using eighth inch fader start cables (not included.) Any connected device can then
be remotely started using the Crossfader (Section 7 "Special Crossfader Related Features.) "Fader Start"
must be switched to the on position for this feature to work properly.
NOTE: These terminals are only compatible with Digital Pulse Style Reception Devices

PAGE 16
AC In and Power Switch
This mixer uses an IEC type power cable. Make sure that the Internal Voltage Selector Switch is properly
set before inserting the power cable into the mixer. The mixer should be switched on after all devices are
already connected to prevent damage to your equipment. A Blue Power LED indicates that the unit has
been switched on (See Section 3 "Meters and Lighting.")
Internal Voltage Selector Switch
This switch allows the voltage for the mixer to be set at 110 VAC or 240 VAC (dependent on region and
plugtype.) To switch the voltage setting, remove the top screw on the plastic shield, and rotate the shield
counterclockwise.
