CP 52 - FRONT PANEL
햲
PAGING TRIM
control adjusts the Page Input preamplifier gain to match the microphone/source in use,
not
to set the Page
level in the Zone Output. The range is 30 dB to 60 dB.
햳
PAGING MIC/LINE
switch selects a 30 dB Input Pad when set to LINE.
Phantom Power is disabled when LINE is selected.
햴
PAGING DETECT THRESHOLD
sets the Page signal level required to gate a Page
on
and illuminate the ACTIVE
indicator (see
햶
). The range is -
∞
(on) to +4 dBu.
햵
PAGING OL (Overload)
indicator lights when the Page Input preamplifier comes within 3 dB of clipping.
햶
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).
햷
PAGING LEVEL
control adjusts the Paging Level in the Zone.
햸
PAGING LIMIT THRESHOLD
control sets the maximum output level for a Page. This is a true voltage Limiter circuit
with a ratio of 15:1. The Threshold range is -20 dBu to +20 dBu. The
THRESHOLD
indicator lights during limiting.
햹
PROGRAM INPUT LEVEL
controls allow independent adjustment of level for each Program Input.
햺
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.
햻
ZONE DUCKER OFF/ON
switch turns the Ducker ON or OFF.
햽
ZONE PROGRAM SELECT
switch assigns one of four Program Inputs to the Zone Output.
햾
ZONE RMT
switch, when pushed
in
, turns control of Zone Level and Zone Program Selection over to the Zone Remote
Port. Front panel ZONE LEVEL and ZONE PROGRAM SELECT controls are
inactive
when RMT is selected. An optional
wired ZR 1 remote may be connected to the Zone Remote Port.
An object smaller in diameter than the switch button is
required to engage the RMT switch.
햿
ZONE SIG/OL
indicators show Signal present at -20 dBu and Overload at +16 dBu (4 dB before clipping) respectively.
헀
ZONE LEVEL
control
adjusts the overall Level for the Zone Output. If the rear panel PAGE LEVEL TRACKS ZONE
LEVEL switch is ON, this control also effects the Paging Level.
헁
ZONE LIMIT THRESHOLD
control sets the maximum level for the Zone Output. This is a true voltage Limiter circuit
with a ratio of 15:1. The Threshold range is -20 dBu to +20 dBu. The
THRESHOLD
indicator lights during Limiting.
헂
GRAPHIC EQUALIZER
controls are “stereo,” with each slider controlling the response of both Left and Right channels.
These controls allow ±12 dB adjustment of seven ISO center frequencies on 1
1
/
3
octave centers.
헃
PWR
indicator lights when the CP 52 is connected to a powered RS 1 power supply.
