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
recommended set up procedure, you should get at least a “B.”
Keep the amplifiers and the CP 64 turned off until all connections 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. The factory default settings work for many applications. How-
ever, 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. The default is off.
• The Page Priority switch assigns priority override to Page 1, Page 2 or NO (none). The default is Page 1. If a Page has
priority, it overrides the non-priority Page in the Zone(s) it is assigned. The 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.
The default is Pre-VCA.
• The Zone 1 Stereo/Mono switch default is Stereo.
• There are two internal trim controls for the Program Priority detector. The Program Priority Threshold trim has a range
of -
∞
to -35 dBu with a default of -50 dBu. The Program Priority Release Time has a range of 2 to 20 seconds. The
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
control, 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. These inputs are also TTL compatible (0 to 5 VDC). See wiring details on pages Manual 9-10.
PROGRAM INPUTS:
Connect Program sources to the RCA
PROGRAM INPUTS
(L1, L2, L3 & P.) If you have a
priority program, like a jukebox, connect it to the
PRIORITY
Input. The Program PRIORI
TY 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
Euroblock for each Zone as required. These are cross-coupled
line drivers and may be used balanced or unbalanced. Each Expand Output can be Page-only, Program-only or Zone
signal. The 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. These 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
separately), wire it to the rear
REMOTES
Euroblock as indicated. If a ZR 1 remote is not used, any simple switch closure
to GND will work for the D0 and D1 pins. These pins are TTL compatible (0 to 5 VDC). The 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 9-10.
The CP 64 is very versatile. While this makes a large number of system applications possible, it also results in complex-
ity. For this reason, it is important to use an organized approach for setup and calibration. A highly recommended setup
procedure appears on page Manual-11. By following it you will encounter fewer problems and reduce the need to increase
our collective phone bills.
