sales receipt for warranty purposes.
2. All operating instructions should be read before using this equipment.
3. 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.
4. Do not expose this unit to direct sunlight or to a heat source such as a
radiator or stove.
5. This unit should be cleaned only with a damp cloth. Avoid solvents or
other cleaning detergents.
6. When moving this equipment, it should be placed in its original carton
and packaging. This will reduce the risk of damage during transit.
7. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
8. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
Connections
1. Before plugging in the power cord, make sure that the VOLTAGE
SELECTOR (38) switch is set to the correct voltage.
NOTE
2. Make sure that the POWER (1) switch is in the off position.
3. The PS-646 PRO2 is supplied with 2 sets of amp output jacks. The
MASTER BALANCED OUTPUT (39) 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 25 feet or more.
Balanced 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 OUTPUT AMP (40) jacks are unbalanced and used to connect to
your main amplifier. The OUTPUT BOOTH (41) jacks allow you to hook
up an additional amplifier.
4. The MIC 1 (3) input (found on the front panel) accepts an XLR
connector. The MIC 2 (50) input (found on the rear panel) accepts 1/4"
connectors. Each accept balanced and unbalanced microphones.

5. On the rear panel are 1 stereo PHONO/LINE (49) input, 2 stereo
PHONO (45, 47) inputs, and 5 stereo LINE (42, 43, 44, 46, 48) inputs.
The PHONO/LINE SWITCH (51) enables you to set the (49) input to
Phono or Line. The phono inputs will accept only turntables with a
magnetic cartridge. A GROUND SCREW (52) for you to ground your
turntables is 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
HEADPHONE (2) jack OR headphones can plugged into the
HEADPHONE (23) jack located on the side of the mixer.
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 (53) in the left
position).
2. Then turn the power off before moving the GROUND LIFT SWITCH
(53). 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.

6. CROSSFADER SECTION: The CROSSFADER (22) allows the mixing of
one source into another. The PS-646 PRO2 features an assignable
crossfader. The ASSIGN (19, 20) switches allow you to select which
