QUICK START
If you were the type that cheated on school book reports
by just skimming through the reading assignments, then this
section is for you! It gives you not quite enough information to
really know what you’re doing. But, if you follow the recom-
mended set up procedure, you should get at least a “B.”
Keep the amplifiers and the CP 64 turned off until all connec-
tions are made.
INTERNAL SETTINGS: Access to the following internal
controls requires removal of the top cover. All internal settings
should be complete before you install the CP 64. e factory
default settings work for many applications. However, you may
need to change one or more for your system. See the INTERNAL
ADJUSTMENTS description on page Manual-8 for more details
• Each Page Input has a 15 volt Phantom Power switch. e
default is off
.
• e Page Priority switch assigns priority override to Page
1, Page 2 or NO (none). e default is Page 1. If a Page has
priority, it overrides the non-priority Page in the Zone(s) it is
assigned. e NO priority setting allows the Pagers to mix.
• Each Page Input may sum with the Program Pre- or Post-
VCA. When set to Pre-VCA, Zone Level, EQ and Limiter
circuits act upon the Page. When summed Post-VCA, the
Page is not influenced by Zone Level, EQ or Limiter circuits.
e default is Pre-VCA.
• e Zone 1 Stereo/Mono switch default is Stereo.
• ere are two internal trim controls for the Program Priority
detector. e Program Priority reshold trim has a range of
-∞ to -35 dBu with a default of -50 dBu. e Program Priority
Release Time has a range of 2 to 20 seconds. e default is 12
seconds.
PAGE INPUTS: Connect Page Inputs to the Euroblock on
the rear panel and select the appropriate MIC or LINE switch
position for each. First, set the gain with the Page TRIM con
-
trol, then set the Page DETECT THRESHOLD and finally the
Page Zone LEVEL.
PR 2 REMOTE: If you use the optional PR 2 remote (sold
separately), wire it to the rear RMT ZONE ASSIGN Euroblock

as indicated. If you require remote control but do not wish to
use a PR 2, any simple switch closure to GND will work. ese
inputs are also TTL compatible (0 to 5 VDC). See wiring details
on pages Manual 5-6.
PROGRAM INPUTS: Connect Program sources to the
RCA PROGRAM INPUTS. If you have a priority program,
like a jukebox, connect it to the PRIORITY Input. e Pro
-
gram PRIORITY ASSIGN switch assigns priority override to
Off, Zone 1, Zone 2, or Both. In the Zone(s) that it is assigned,
the priority program is automatically selected when signal is
detected.
EXPAND OUTPUTS: Wire the EXPAND OUTPUT Eu
-
roblock for each Zone as required. ese are cross-coupled line
drivers and may be used balanced or unbalanced. Each Expand
Output can be Page-only, Program-only or its Zone signal. e
Zone source will not include the Page if the Page is summed Post-
VCA. Page is always available from the Page source.
ZONE OUTPUTS: Wire the two ZONE OUT Euroblocks
as required. ese are cross-coupled line drivers and may be used
balanced or unbalanced. Set the LIMIT threshold as required.
ZR 1 REMOTE: You may use one or two ZR 1 Remotes
with each CP 64. If you use the optional ZR 1 remote (sold sepa
-
rately), wire it to the rear REMOTES Euroblock as indicated. If
a ZR 1 remote is not used, any simple switch closure to ground
will work for the D0 and D1 pins. ese pins are TTL compat-
ible (0 to 5 VDC). e logic is inverse Gray Code. Any ground
referenced 5 volt DC control may be used as the input to V
1
or
V
2
. Do not ground the Vr
1
or Vr
2
pins. See wiring details on pages
Manual 5-6.
e CP 64 is very versatile. While this makes a large number
of system applications possible, it also results in complexity. For
this reason, it is important to use an organized approach for setup
and calibration.
A highly recommended setup procedure appears
on page Manual-7. By following it you will encounter fewer prob-
lems and reduce the need to increase our collective phone bills.
