COMMERCIAL PROCESSOR
Quick Start
If you were the type that cheated on school book reports by just
skimming through the reading assignments, then this page 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 CP64S 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 CP64S, before you attach the power cable. The fac-
tory default settings work for many applications. However, you
may need to change one or more for your system. See "Internal
Adjustments" on page 9 if you want to change these defaults:
• 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 Post-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 Prior-
ity 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 .

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. The Program
PRIORITY ASSIGN ZONE
switch assigns priority override to Off, Zone 1 , Zone 2 , or Both .
In the Zone(s) that it is assigned, the priority program is auto-
matically 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 its Zone signal. The Zone source will not include
the Page if the Page is summed Post-VCA. Page is always avail-
able 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 unbal-
anced. Set the
LIMIT
threshold as required.
ZR1 REMOTE
You may use one or two optional ZR1 Remotes (sold separately)
with each CP64S. If you use the ZR1, wire it to the rear
REMOTES
Euroblock as shown on page 11. If a ZR1 remote is
not ideal, any simple switch closure to ground 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 .
SETUP ADVICE
The CP64S 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. Please read and follow the "Recommended Cali-
bration Procedure" on page 13. This will avoid problems and
reduce the need to increase our collective phone bills.
