three year warranty, excluding crossfader and channel slides. Prior to
use, we suggest that you carefully read all the instructions.
Cautions

2. To reduce the risk of electrical shock, do not open the unit. There are
NO USER REPLACEABLE PARTS INSIDE. Please refer servicing to
a qualified service technician.

a radiator or stove.
4. This unit should be cleaned only with a damp cloth. Avoid solvents or
other cleaning detergents.

pin of the adaptor into the rear panel POWER JACK (7). Then plug
the adaptor into a proper power source.
2. Make sure that the POWER (6) switch is in the off position. The
POWER LED (12) will be off.
3. To connect the mixer to your amplifier, use the OUTPUT AMP (1)
jacks on the rear panel.
4. On the rear panel are 2 stereo PHONO (3, 5) inputs and 2 stereo
LINE (2, 4) inputs. The PHONO (3, 5) inputs will accept turntable
inputs only. A GROUND (8) screw for you to ground your turntables
is located on the rear panel. The stereo LINE (2, 4) inputs will accept
any line level input like a CD player or a cassette player.
5. Headphones can be plugged into the front panel mounted
HEADPHONE (18) jack.

your mixer, press the POWER (6) switch. The power will turn on and
the POWER LED (12) will glow RED.
2. CHANNEL 1: The CHANNEL LEVEL SLIDE (10) allows you to fully
adjust the level of the selected source. The PHONO/LINE (9) switch
allows you to select either Line 1 or Phono 1 to play through
channel 1.
3. CHANNEL 2: The CHANNEL LEVEL SLIDE (17) allows you to fully
