Output PC Board
The output pc board has wiring designations on the front edge of the PC board layout.
The layout below is from left to right there are three rows of terminal strips for wiring.

1. Utility Left + (mix minus 1)
2. Utility Left–
3. Ground
4. Ground
5. Utility Right + (mix minus 2)
6. Utility Right Update note add two 100 ohm resistors in series with the Utility Right + and – outputs. Use one
for the + output and one for the – output. Now connect your wire to the resistor side instead of
directly connecting it to the utility terminal strip. This update will prevent the utility amplifier from
oscillating and burning up.

Auto Cue Connector
The auto cue is a feature where the earphone automatically switches to its autocue function
whenever any channel is placed into the cue detent position from the slide fader. By moving the
autocue jumper wires you may select different autocue options for the earphone. The connector
is located on the output PC board back center in front of the DC power connector.

B. Earphone Mono Mix Output
C. Cue Left Output
D. Cue Right Output

To disable the autocue remove the second 10K ohm resistor below the reed relays. This resistor
is next to the black heatsink the location is shown below.

The channel control card is located on the top lid of the console and has the Program and
Audition switches mounted to it. The 500 and 2100 consoles use the ‘A’ contacts, which are wired
through the A/B switch for the remote start logic. This shows up on the input pc boards Remote
Start terminal and is switched to the Ground terminal. However, you do have the additional spare
‘B’ relay contacts that may be used for an isolated remote start closure.

The jumpers are located on the power supplies AC transformer input side.
For 120 VAC operation connect a jumper between pins 1 and 3 and connect a second jumper
between pins 2 and 4 this is the factory default for audio consoles shipped in the USA. For 220
VAC operation remove the jumpers shown above and connect a jumper between pins 2 and 3.
Be sure to change the jumpers on both of the 1.5 amp as well as the 3.0 amp power supplies.
Power DIP Switches and Settings
There are 3 DIP switches on the output PC board they all control the plus and minus DC power
supply voltages to specific sections of that PC board.
DIP Switch 1 is located underneath the Buss Input connector, which is at the top left hand corner.
Below this connector are two LED’s for the (+) and (-) DC power input from the power supply. The
blue DIP switch is located under the LED’s.

Switch 2 (-) DC for the Metering section.
The metering section includes Program VU meter left right, Audition VU meter left right, Monitor
input left right and the Mono microphone preamp.
Switch 3 (+) DC for the Program section.
Switch 4 (-) DC for the Program section.
The Program section includes Program left right, Audition left right, Program mono, Audition
mono and Utility right.
DIP Switch 2 is located between the two rows of black heatsinks on the left hand side next to the
left hand row of black heatsinks.

Buss Input Connector
The buss input connector is a short ribbon cable which is used to connect the input and output
PC boards together. This cable connects the DC power supply voltage, audio buss signals and
logic functions to and from the PC boards.
This 20 pin male ribbon connector is no longer available. To repair remove the top cover and
discard remove the ribbon cable and connect each pin location with a jumper wire. Use a 3 inch
length of insulated wire and strip both ends 1/16 inch from the end and solder to the top ribbon
connection for each of the 20 pins. Example connect pin 1 from connector A to pin 1 on connector
B repeat until you connect all 20 pins.
If your female 20 pin connector is defective, remove it from the PC board and just jumper each
trace location over with the same insulated jumper wire as shown above.

Pin 20 on the newer Turbo series PC boards will go to the Utility Left summing amplifier located
on the output PC board. However this amplifier input is not connected on the input PC boards and
requires a custom modification to use the Utility Left amplifier. The SC series audio consoles only
used the Utility Right amplifier. This Mix Minus buss was used to send audio back to the phone
caller. Connect the Utility Right output to the phone hybrids send input.
Clock and Timer Connector for 150, 500, 2000sc
The optional ESE 172 Clock and the ESE 570 Timer control wiring is brought out to a 12 pin
terminal strip mounted on the VU meter panel. These Clocks and Timers are no longer available.

To control the Timer switch it’s logic functions to the Timer ground
To control the Clock switch it’s logic functions to the Clock ground
Convert a Stereo Line Input to Microphone Level
The audio level jumpers are located above the “A” input terminal strip it looks like the following.
/\ /\
J
\/ \/
Install two wires from the bottom \/ to the top /\ PC trace.
Next make the mono input show up on both the Left and Right channels.
This jumper is located between the left NE5532 and the left SSM2013 VCA it looks like the
following.
1 2 3
OOO
For left right Stereo add a jumper from 2 to 3
For mono Microphone add a jumper from 1 to 3
Use only one jumper wire.
If you would like the input channel to mute the monitor speakers locate the M just in front of the
Channel Control Connector. You will notice a side ways T add a wire jumper from the bottom PC
trace to the top PC trace.
