INTRODUCTION:
Congratulations on purchasing the UMX DIVISION UMX-SE VCA mixer.
This state of the art mixer is backed by a three year warranty, excluding
CROSSFADER and channel slides. Prior to use, we suggest that you
carefully read all the instructions. With VCA technology, audio is
processed in a voltage-control LED amplifier (VCA) removing it from the
CROSSFADER and channel slides giving them extended life and
reducing travel noise. The CROSSFADER and channel slides regulate
the DC voltage that controls the VCA circuit. Additional advantages of
VCA technology include the ability to provide precise curve adjustments
for the CROSSFADER and channel slides without sacrificing audio
quality. For additional information, refer to the diagrams on PAGE 3 for
CROSSFADER adjustment and channel slide curve.

HEIGHT ADJUSTMENT:
When using a UMX mixer with professional turntables, such
as the UMX DIVISIONPT Series, you can make the mixer
level with the turntable by removing the mixer’s feet.
1. Place a small screw driver under the foot’s center anchor.
2. Gently pry the center anchor up and the foot will come OFF.
To replace the foot:
1. Place the foot on the mixer without the center anchor.
2. Replace the center anchor and push down on it to anchor the foot to the
mixer.
CONNECTIONS:
1. Before plugging in the power cord, make sure that the VOLTAGE
SELECTOR (1) switch is set to the correct voltage.
2. Make sure that the POWER (8) switch is in the OFF position. The
POWER LED (20) will be OFF.
3. The UMX-SE is supplied with 4 sets of output jacks. The BALANCED
MASTER OUTPUT (9) jacks are used to connect to your main amplifier
using standard XLR cables. We recommend using the balanced amp
outputs if the cables to your amp are 10 feet or more. BALANCED
MASTER OUTPUTS have three separate conductors, two of which are
signal (positive and negative) and one shield (ground). Pin 1 is ground
(shield). Pin 2 is signal hot (positive). Pin 3 is signal cold (negative). The
MASTER OUTPUT (11) jacks are unbalanced and used to connect to
your main amplifier. The REC OUTPUT (10) jacks can be used to
connect the mixer to the record input of your recorder enabling you to
record your mix. The ZONE OUTPUT (12) jacks allow you to hook up an
additional amplifier.
4. The MIC (7) input (found on the rear panel) accepts a 1/4" connector
and balanced and unbalanced microphones.
5. On the rear panel are 3 stereo PHONO/LINE (14, 16, 17) inputs and 2
stereo LINE (13, 15) inputs. The PHONO/LINE SWITCH (3) enables you
to set the (14) input to Phono or Line. The PHONO/LINE SWITCH (4)
enables you to set the (16) input to Phono or Line. The PHONO/LINE
SWITCH (6) enables you to set the (17) input to Phono or Line. The
phono inputs will accept only turntables with a magnetic cartridge.
GROUND SCREWS (5) for you to ground your turntables are located on
the rear panel. The stereo line inputs will accept any line level input such
as a CD player, a cassette player, etc.
6. Headphones can be plugged into the front panel mounted PHONES (45) jack.
USING THE GROUND LIFT SWITCH:
Depending on your system configuration, sometimes applying the ground
will create a quieter signal path. Sometimes lifting the ground can
eliminate ground loops and hum to create a quieter signal path.
1. With the mixer on, listen to the system in idle mode (no signal present)
with the ground applied (the GROUND LIFT SWITCH (2) in the left
position).
2. Then turn the power OFF before moving the GROUND LIFT
SWITCH (2). Lift the ground by moving the GROUND LIFT SWITCH to
the right, turn the power back on and listen to determine which position
will provide a signal devoid of background noise and hum. Keep the
GROUND LIFT SWITCH in the ground position if the noise level remains
the same in either position.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER MIXER IN ANY WAY.
TERMINATION OF THE AC GROUND CAN BE HAZARDOUS.
OPERATION:
1. POWER ON: Once you have made all the equipment connections to your
mixer, press the POWER (8) switch. The power will turn on and the
POWER LED (20) will light.
2. CHANNEL 1: The GAIN (23), HIGH (24), MID (25), LOW (26), and PAN
(27) controls allow you to fully adjust the selected source. Switch # (29)
allows you to select the PHONO 1/LINE 1 (17) or the MIC (7) input. The
CHANNEL SLIDE (33) controls the input level of this channel.
3. CHANNEL 2: The GAIN (23), HIGH (24), MID (25), LOW (26), and PAN
(27) controls allow you to fully adjust the selected source. Switch # (30)
allows you to select the PHONO 2/LINE 2 (16) or the LINE 3 (15) input.
The CHANNEL SLIDE (34) controls the input level of this channel.
4. CHANNEL 3: The GAIN (23), HIGH (24), MID (25), LOW (26), and PAN
