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.)

interrupted, input signals are bypassed
directly to the corresponding outputs.
The front panel may be removed without
affecting control settings, and each
equalization stage resides on a separate,
gold-socketed circuit card for ease of
service. An optional smoked plastic security
cover discourages tampering in fixed
installations.

The clearly marked front panel includes
individual in/out switches for each equal-
ization band, with separate, calibrated
frequency, bandwidth and boost/cut
controls. LEDs indicate power status and
signal clipping.
Signal flow through the device is
controlled by a delayed relay which allows
the CP-10 circuitry to stabilize before it is
engaged. When power to the CP-10 is
