all the way down, decrease the 

program trim

 level. Any change in the 

program trim

 level control on the rear panel to adjust for one channel will 

necessitate adjustments on the other channel to compensate.

Note: Do not force the controls past their stop points as this will 

damage them.

5.

TEST TONE:

 This toggle switch turns on a test tone which can be heard 

on either or both channels when the 

program send

 switch for that channel 

is in the 

off

 position. It can be handy for identifying which intercom 

channel is which or for other test purposes. The 

program send level

 

controls adjust the level of the test tone on each channel.

6.

A+B LINK SWITCH and INDICATOR:

 This toggle switch links the 

audio for channels A and B together. A yellow light indicates when the 

channels are linked. It can be useful to have both channels linked for 

rehearsals, but separated for performances. 

7.

INTERCOM LINE CONNECTOR and SWITCH:

 A single 

intercom 

line

 connector is located on the front panel for convenience. It can be 

switched between channels 

and 

B

 with the associated toggle switch.

PROGRAM INPUT:

 This three-pin female XLR jack accepts a balanced 

or unbalanced line-level signal. This is typically a feed from a mixing 

console, an air feed from a studio to remote site over a phone line, or an 

audio cue track. Send levels to the individual channels are controlled with 

a combination of the 

program trim

 level and the 

program send

 levels on 

the channels. This feed can be fed to either or both intercom lines.

9.

AUDIO ADJUST:

 This control adjusts the overall input level of the 

external program coming into the PS-702. It is used with the 

program 

send level 

controls to achieve desired system program levels. Turn the 

control clockwise to increase the gain and counter-clockwise to reduce it.

Note: Do not force this control past its stop points as this will damage 

it.

10.

TERM. ON/OFF:

 These switches (one per channel) select whether the 

PS-702 will provide the required termination for each channel. These 

should 

always 

be 

on

 unless there are other power supplies or terminated 

main stations in the system. If there are other possible terminations in the 

system, all but one must be turned 

off

.

11.

INTERCOM LINE CONNECTORS:

 There are three 3-pin male XLR 

jacks per channel, wired in parallel, or looped through. All the stations in 

the system are ultimately connected to the PS-702 through these jacks. 

Because intercom audio is bidirectional, they are neither inputs nor 

outputs, but may be thought of as “ports.” 

Pin #1

 is connected to the 

shield and carries the signal ground. 

Pin #2

 carries the DC voltage that 

runs the remote stations. 

Pin #3

 carries two way audio and call signals.

12.

AC POWER SUPPLY INPUT:

 Connects to AC with an IEC cable. The 

PS-702 will accept any line voltage between 100 and 240 volts AC at 

50 to 60 Hz. It will automatically adjust to the line voltage. There is no 

need for a selector switch or an external fuse.
