The REC OUTPUT (41) (RCA type) jacks can be used to
connect the mixer to the record input of your recorder
enabling you to record your mix.
The BOOTH OUTPUT (40) (RCA type) jacks allow you to
hook up an additional amplifier.
4. The MIC 1 (1) input (found on the front panel) accepts XLR &1/4"
connectors. The MIC 2 (56) input and the MIC 3 (55) input (found
on the rear panel) accept 1/4" connectors. All accept balanced and
unbalanced microphones.
5. On the rear panel are three (3) stereo PHONO/LINE (47, 50, 53)
inputs and 5 stereo LINE (44, 45, 46, 49, 52) inputs.
The PHONO/LINE SWITCH (48) enables you to set the (47)
input to Phono or Line.
The PHONO/LINE SWITCH (51) enables you to set the (50)
input to Phono or Line.
The PHONO/LINE SWITCH (54) enables you to set the (53)
input to Phono or Line.
The phono inputs will accept only turntables with a magnetic cartridge.
6. A turntable GROUND SCREW (57) is located on the rear panel.
7. Headphones can be plugged into the front panel mounted
HEADPHONE JACK (36) .
8. The PS-850i features a front panel BNC LIGHT JACK (30) . This
jack is for a gooseneck lamp such as the Gemini GNL-700.
9. There are LOOP INPUTS (43) and LOOP OUTPUTS (42) located on
the rear panel. If you are using an outboard signal processor, you
can use the LOOP OUTPUTS (42) to send the signal to the device
and the LOOP INPUTS (43) to bring the signal back in to the mixer.
The unit comes with jumpers to be used with the loop inputs and
outputs. Keep the jumpers in the unit if you are not using the loop to
prevent interruptions in your music program.
THE GROUND LIFT SWITCH
D
epending on your system configuration, applying the ground
sometimes creates a quieter signal path. Sometimes “lifting” the
ground eliminates loops and hum to create a quieter signal path.
1. Listen to the system with the unit ON, without music, and with the
ground “applied.” GROUND LIFT SWITCH (58) should be to the left.
2. Turn power OFF before moving the GROUND LIFT SWITCH.
3. Now, “lift” the ground by moving the GROUND LIFT SWITCH to the
right. Turn the power back ON and listen to determine which position
provides a signal free of background noise and hum.
Note: Keep GROUND LIFT in the ground “applied” or left
position if noise level remains the same in either position.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER
CABLE. 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 (31). The power will
turn on and the POWER LED (32) will “glow” RED.
2. CHANNEL 1: The GAIN (8), HIGH (9), MID (10), and LOW (11)
controls allow you to fully adjust the selected source. Switch (12)
allows you to select the PHONO 1/LINE 1 (53) or the LINE 2 (52)
input. CHANNEL SLIDE (13) controls the input level of this channel.
3. CHANNEL 2: The GAIN (8), HIGH (9), MID (10), and LOW (11)
controls allow you to fully adjust the selected source. Switch (14)
allows you to select the PHONO 2/LINE 3 (50) or the LINE 4 (49)
input. CHANNEL SLIDE (15) controls the input level of this channel.
4. CHANNEL 3: The GAIN (8), HIGH (9), MID (10), and LOW (11)

NOTE: This product is double insulated
and is not intended to be grounded.
2. Make sure that the POWER (31) switch is in the OFF position.
The POWER LED (32) will be OFF.
3. The PS-850i is supplied with four (4) sets of output jacks.
The XLR BALANCED OUTPUT (38) jacks are used to
connect to your main amplifier using standard XLR cables.
We recommend using balanced amp outputs if the cables to
your amp are 10 feet or more. XLR 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 MAIN OUTPUT (39) (RCA type) jacks are unbalanced
and used to connect to your main amplifier.
