Cautions
1. Always test equipment before rack mounting. Retain a copy of your
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.
In the U.S.A., if you have any problems with this unit,
call 1-732-969-9000 for customer service. Do not return
equipment to your dealer.
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 (36) switch is set to the correct voltage.
NOTE: This product is double insulated and not intended
to be grounded.
2. Make sure that the POWER (1) switch is in the off position. The
POWER LED (2) will be off.
3. The PS-1000 PRO is supplied with 2 sets of amp output jacks. The
BALANCED OUTPUT AMP (49) 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 (37) jacks are unbalanced and used
to connect to your main amplifier. The OUTPUT BOOTH (38) jacks
allow you to hook up an additional amplifier.
4. The MIC 1 (3) input (found on the front panel) accepts a 1/4" or XLR
connector.
The MIC 2 (51) input and the MIC 3 (50) input (found on
the rear panel) accept 1/4" connectors. All accept balanced and
unbalanced microphones.
5. On the rear panel are 1 stereo PHONO/LINE (46) input, 2 stereo
PHONO (42, 44) inputs, and 5 stereo LINE (39, 40, 41, 43, 45)
inputs. The PHONO/LINE SWITCH (48) enables you to set the (46)
input to Phono or Line. The phono inputs will accept only turntables
with a magnetic cartridge. A GROUND SCREW (47) 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 (13) 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 (52) in
the bottom position).
2. Then turn the power off before moving the GROUND LIFT
SWITCH (52). Lift the ground by moving the GROUND LIFT SWITCH
to the top position, 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 SWITCH (1). The power will turn on
and the POWER LED (2) will glow.
2. CHANNEL 1: The GAIN (14), HIGH (15), MID (16), and LOW (17)
controls allow you to fully adjust the selected source. Switch # (18)
allows you to select the PHONO 1/LINE 1 (46) or the LINE 2 (45)
input. The CHANNEL SLIDE (19) controls the input level of this
channel.
3. CHANNEL 2: The GAIN (14), HIGH (15), MID (16), and LOW (17)
controls allow you to fully adjust the selected source. Switch # (21)
allows you to select the PHONO 2 (44) or the LINE 3 (43) input. The
CHANNEL SLIDE (22) controls the input level of this channel.
4. CHANNEL 3: The GAIN (14), HIGH (15), MID (16), and LOW (17)
controls allow you to fully adjust the selected source. Switch # (23)
allows you to select the PHONO 3 (42) or the LINE 4 (41) input. The
CHANNEL SLIDE (24) controls the input level of this channel.
5. CHANNEL 4: The GAIN (14), HIGH (15), MID (16), and LOW (17)
controls allow you to fully adjust the selected source. Switch # (25)
allows you to select the LINE 5 (40), LINE 6 (39) or the MIC 3 (50)
input. The CHANNEL SLIDE (26) controls the input level of this
channel.
NOTE: There is Low, Mid and High equalization for each
channel with an extremely wide range of adjustment
providing a smoother mix.
