Notes:
1. All equalization circuits
out.
2. 1 kHz input at +4 dBu
3. “A” weighted noise floor
to maximum RMS output
4. Within the operating band
of each channel, maxi-
mum input level is the
minimum worst-case
level achieved before
clipping.
A ground lift switch floats audio
common (XLR connector pin 1) from
the chassis. (Earth and chassis are
always connected for safety.)
A gain switch adjusts for unity gain
with either balanced or unbalanced
input signal connections. (Outputs
remain balanced at all times.)

LEDs indicate power status and
gaged. When power to the CP-10S is inter-
rupted, input signals are bypassed directly
to the corresponding outputs.
The front panel may be removed without
affecting control settings, and each equal-
ization stage resides on a separate, gold-
socketed circuit card for ease of service. An
optional smoked plastic security cover dis-
courages tampering in fixed installations.
The clearly marked front panel includes
individual in/out switches for each equal-
ization band, with screwdriver-adjustable
frequency, bandwidth and boost/cut con-
trols. LEDs indicate power status and sig-
nal clipping.
Signal flow through the device is con-
trolled by a delayed relay which allows the
CP-10S circuitry to stabilize before it is en-
