CP 31 - FRONT PANEL
PAGING TRIM
control is used to adjust the Page Input preamplifier gain to match the microphone/source in use,
not
to set
the Page level at the Zone Output. The range is 30 dB to 60 dB.
PAGING MIC/LINE
switch selects a 30 dB Input pad when set to LINE.
PAGING DETECT THRESHOLD
sets the Page signal level required to gate a Page
on
and illuminate the ACTIVE
indicator (#5). The range is -
∞
(on) to +4 dBu.
PAGING OL (Overload)
indicator lights when the Page Input preamplifier comes within 4 dB of clipping.
ACTIVE
indicator lights when the Page signal level reaches the Paging Detect Threshold.
Note that a Page is always Active
when the PAGING DETECT THRESHOLD is set to minimum (ccw).
PAGING ASSIGN
switch selects whether the Page signal is sent to Zone A, Zone B, BOTH Zones, or OFF (no Zones).
PAGING LEVEL
controls adjust the Paging Level in each of the two (A & B) Zones.
PROGRAM INPUT LEVEL
controls allow independent level adjustment for the stereo or dual mono Program Input(s).
ZONE DUCKER DEPTH
control
sets the Ducker Depth (the amount of Program attenuation during a Page) from 50 dB
(ccw) to 6 dB (cw). The Ducker
release
is ramped and not user-adjustable.
ZONE DUCKER OFF/ON
switches independently turn each Ducker ON or OFF.
ZONE Output Meter
displays PEAK signal levels at -10 dBu, +4 dBu, and +16 dBu.
ZONE LEVEL
controls
adjust the overall Level for each Zone Output. This concentric pot allows independent adjustment
of Output Levels, or “stereo/master” level control by holding both the inner and outer knobs together.
PWR
indicator lights when the CP 31 is connected to a powered RS 1 power supply.
