CP52S Front Panel
1
PAGING INPUT TRIM
control adjusts the Page Input preamplifier gain to match the microphone / source in use. The range is
30 dB to 60 dB.
2
PAGING INPUT MIC / LINE
switch selects a 30 dB Input pad when set to LINE.
Phantom Power is disabled when LINE is
selected.
3
PAGING DETECT THRESHOLD
sets the Page signal level required to gate a Page
on
and illuminate the ACTIVE indicator
(see
5
). The range is -∞ (on) to +4 dBu.
4
PAGING OL (Overload)
indicator lights when the Page Input preamplifier comes within 3 dB of clipping.
5
PAGING ACTIVE
indicator lights when the Page signal level reaches the PAGING DETECT THRESHOLD.
A Page is always
Active when the PAGING DETECT THRESHOLD is set to minimum
(ccw)
.
6
PAGING LEVEL
control adjusts the Paging Level in the Zone.
7
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
LIMIT
indicator lights during limiting.
8
PROGRAM INPUT LEVELS
allow independent adjustment of level for each Program Input.
9
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.
0
ZONE DUCKER OFF / ON
switch turns the Ducker ON or OFF.
q
ZONE PROGRAM SELECT
switch assigns one of four Program Inputs to the Zone Output, only when
w
is
out
.
w
ZONE REMOTE
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 REMOTE is selected. An optional
wired ZR1 remote may be connected to the Zone Remote Port.
An object smaller in diameter than the switch button is required to
engage the REMOTE switch.
e
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.
ZONE SIG and OL
indicators assist in setting the LEVEL control, il-
luminating with Signal present at -20 dBu and Overload at +16 dBu (4 dB before clipping) respectively.
r
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
LIMIT
indicator lights during Limiting.
t
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.
y
POWER
indicator illuminates when the CP52S is connected to a proper power source.
