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 64S 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 in-
stall the CP 64S, before you attach the power cable. The 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-4 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

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 page Manual-5
.
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
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 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.
ZR 1 REMOTE
You may use one or two ZR 1 Remotes with each CP 64S. 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 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.
See wiring details on page Manual-5.
SETUP ADVICE
The CP 64S 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.
