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. 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. 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 PostVCA. 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
WEAR PARTS: This product contains no wear parts.
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 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. 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 PostVCA. 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 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 V1 or
V2. Do not ground the Vr1 or Vr2 pins. See wiring details on pages
Manual 5-6.
The 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 problems and reduce the need to increase our collective phone bills.

 PAGING ZONE ASSIGN switches select the zone(s) a Page signal is sent to. The RMT position activates the rear panel RMT
ZONE ASSIGN port, allowing the optional PR 2 wired remote to assign the active page Zone(s).
 ACTIVE indicators light when a Page input signal reaches the Page Detect Threshold. Note that a Page is always Active when its Page
Detect Threshold is set to minimum.
 ZONE 1 and ZONE 2 PAGING LEVEL controls adjust the Paging Level in each Zone.
 PROGRAM INPUT LEVELS “stereo”controls allow independent adjustment of level for each Program Input.
 DUCKER OFF/ON switches turn the Ducker ON or OFF for each Zone.
 DUCKER DEPTH controls allow setting Ducker Depth (the amount of Program attenuation during a Page) from 50 dB (ccw) to
6 dB (cw) for each Zone.
 ZONE PROGRAM SELECT switches assign one of four Program Inputs in each Zone.
 ZONE RMT switches, when pushed in, enable the Remotes port for a Zone. This turns control of Zone Level and Zone Program
Select over to the Remotes port. Front panel Zone LEVEL and Zone PROGRAM SELECT controls are inactive when RMT is
selected. Two optional wired ZR 1 remotes may be connected to the Remotes port. An object smaller in diameter than the switch
button is required to engage the RMT switches.
 ZONE SIG and OL indicators show SIGnal present at -20 dBu and OverLoad at -16 dBu (4 dB before clipping) respectively.
Signal indicators are located pre-EQ and pre-VCA.
 ZONE LEVEL controls adjust the overall Level for a given Zone.
 ZONE graphic EQ controls are provided for each Zone. Zone 1 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 two octave centers.
 POWER indicator lights when the CP 64 is connected to a powered RS 1 power supply.

 Chassis Ground Screw provides a convenient earth (technical) ground connection point. The CP 64 does not ground the chassis
through the power cord. It is important that the unit be grounded.
 POWER jack accepts the cable from a Rane RS 1 remote power supply (included). This is not a telephone jack. Use of a supply not
approved by Rane may damage your unit and void the warranty.
 REMOTES ports provides the wiring interface for two optional ZR 1 wired remotes. Each ZR 1 remote provides remote control of
Zone Level and Zone Program Select functions. Refer to page Manual-6 for details.
 ZONE OUTPUT ports feature balanced, cross-coupled line drivers with Euroblock connectors. Zone 1 is stereo. Zone 2 is mono.
 ZONE LIMIT threshold controls set the maximum output level for each Zone. These circuits are true voltage limiters with a ratio
of 15:1. The threshold range is -20 dBu to +20 dBu
 EXPAND OUTPUT ports feature balanced, cross-coupled line drivers with Euroblock connectors. Zone Expand Outputs are
mono.
 EXPAND switches assign Page-only, Program-only or Zone1 or Zone 2 as the source for each Expand Output.
 PROGRAM PRIORITY ASSIGN switch determines in which Zone(s) the automatic priority override is enabled. Off (none),
Zone 1, Zone 2 or Both are the possible settings. If you do not intend to use the Priority Input as an automatic override Input, do
not assign it with this switch. Use the Zone PROGRAM SELECT switch on the front panel.
 Four PROGRAM INPUTS are provided. Three are non-priority Inputs. The fourth is a Program PRIORITY Input. When signal
is present at the PRIORITY Input, it is automatically selected as the Input source in the Zone(s) it is assigned with the Program
PRIORITY ASSIGN switch.
 RMT ZONE ASSIGN port provides the interface for the PR 2 wired remote. The PR 2 remote is used for Zone assignment of Page
Inputs. Refer to page Manual-6 for details.
 PAGING INPUTS DETECT THRESHOLD sets the Page signal level required to gate a Page on and light the ACTIVE indicator. The range is -∞ (on) to +4 dBu.
 The PAGING INPUTS OL indicator lights when either of the Page Input preamplifiers comes within 3 dB of clipping.
 PAGE 1 and PAGE 2 INPUT TRIM controls adjust Page Input preamplifier gain to match the microphone/source in use, not to
set the page level in the Zones. The range is 30 dB to 60 dB.
 PAGE 1 and PAGE 2 INPUT Euroblock connector provides access to the two balanced instrumentation Paging amplifiers. These
Inputs may be operated balanced or unbalanced.
 PAGE 1 and PAGE 2 INPUT MIC/LINE switches select 30 dB Input Pads when set to LINE. Phantom Power is disabled when
LINE is selected.
Manual-3
INTERNAL ADJUSTMENTS
There are a number of controls inside the CP 64 used to
configure the system for specific applications. Access to these
controls is only required during initial system setup. Set up all
internal controls before the CP 64 is installed in a rack or wired
into a system. Make sure the power is off before removing the
top cover to gain access. Refer to the diagram below for control
locations.
There are five internal switches related to the two Page Inputs:
• Page 1 Phantom Power
15VDC
Default: OFF
• Page 2 Phantom Power
15VDC
Default: OFF
• Page Priority
P1, NO, P2 Default: P1
• Z1 Page
Sum Pre- or Post-VCA
Default: Pre-VCA
• Z2 Page
Sum Pre- or Post-VCA
Default: Pre-VCA
Phantom Power is available for both Page Inputs. If phantom power is required for the intended microphone, then set the
appropriate switch to ON. If a Page Input Mic/Line pad switch is
set to LINE, phantom power is automatically defeated.
Manual-4
The Page Priority switch allows you to select one of the Page
Inputs as a Priority Page Input. The Priority Pager overrides the
non-priority Pager in the Zone(s) it is assigned. It is important
to note that the non-priority Pager may still broadcast in any
Zone that the Priority Pager is not assigned to or not currently
broadcasting in. Set the switch to P1 if you wish Page 1 to have
priority over Page 2. If you wish Page 2 to have priority over Page
1, set the switch to P2. If NO is selected, neither Page Input has
priority and both Pagers may be active at the same time. This allows the Page Inputs to mix for applications like karaoke or PA.
If a Page Input is used for emergency paging, set it as the Priority
Pager.
The Z1 Page and Z2 Page switches allow you to sum Page
signals with Program signals “Pre” (before) or “Post” (after) the
VCA. The VCA is used for Zone Level control and Limiting.
Therefore, if you require the Page Level to be controlled independent of the Program Level, set the switch for that Zone to “Post.”
This is the desired setting for emergency paging. If “Pre” is selected, Paging signals sum with Program signals before the VCA.
In this instance both Page and Program signal levels are affected
by the ZONE LEVEL control. Note the following:
• Zone Level, EQ and Limiter circuits do not affect Page signals
summed Post-VCA.
• Zone Level, EQ and Limiter circuits do affect Page signals
summed Pre-VCA.
• Page signals are not available on the Expand Zone output
when summed Post-VCA.
• Page signals are always available for the Expand Page output.
There are two internal controls related to the Program Priority
detector:
• Priority Release Time
2 sec to 20 sec (trim pot)
Default: 12 seconds
• Priority Threshold
-∞ to -35 dBu (trim pot)
Default: -50 dBu
The default settings for the Program Priority detector are
chosen for most applications. Detector Threshold settings lower
than the default setting of -50 dBu are prone to false triggering unless the source is very quiet. If a source is noisy, you may
wish to set the threshold higher to prevent false triggering. The
default Release Time is 12 seconds. You may wish to decrease
the Release Time if the source is a TV, radio, tape machine or
any other relatively constant signal source. If you have a source
like a jukebox, with relatively long search times, you may wish to
extend the Release Time.
There is one internal control related to Zone 1:
• Zone 1 Mode
Mono/Stereo
Default: Stereo
CP 64 CONNECTIONS
Power to the CP 64 should be OFF until all connections are made.
EUROBLOCK CONNECTIONS
All Input and Output connections are made with Euroblock
connectors except for the RCA Program Inputs. When wiring to
Euroblocks, a minimum wire gauge of 22 is preferred for reliability. If the ground or shield wire is left shorter, it acts as a strain
relief for the other wires. Cable with a flexible jacket is easier to
use and less likely to damage the connections. Avoid stripping
excess insulation. Inspect wires for nicks that may lead to wire
breakage. Fully insert each wire in the appropriate socket and
tighten the screw.
Page Input circuits are true instrumentation amplifier inputs
and operate balanced or unbalanced. Expand and Zone Outputs
are driven by high quality cross-coupled line drivers and operate
balanced or unbalanced. For both Inputs and Outputs, wiring
is basically the same. Balanced operation is recommended. Balanced wiring is straight forward, (+) to (+), (–) to (–) and shield
to shield.
For unbalanced operation, we recommend using two conductor cable with shield. The cable is wired to the CP 64 the same
as for balanced operation. At the other end of the cable, connect
the (+) wire to signal “hot” and both the (–) and shield wires to
ground (important.)
If you use single conductor cable with shield, connect the
shield/gnd wire to both the (–) and shield pins at the CP 64. At
the other end of the cable connect the (+) wire to the signal “hot”
and the shield/gnd wire to ground. When unbalanced wiring
is used, it is very important for the CP 64 and any other unit
in the system to have good earth or technical grounds. If a unit
is located far from the CP 64 or is of a type that might create
grounding problems, isolation transformers should be used.
When operating cross-coupled line drivers unbalanced (i.e., any
CP 64 Output), it is essential to ground the (–) pin.
PROGRAM INPUTS
The four stereo Program Inputs connect to RCA jacks. These
Inputs are unbalanced. The same guidelines given above for
unbalanced operation apply to these Inputs.
Refer to the RaneNote, “Sound System Interconnection“
(included) for additional wiring information.
REMOTE INSTALLATION
The CP 64 supports wired remotes for Page Assign, Zone
Level and Zone Source selection. Wire lengths of up to 1000 feet
are possible. A brief list of suitable wire types is provided in the
WIRE TYPES section on the next page.
The PR 2 remote provides Page Zone Assign for Page 1 and
Page 2 signals and is usually located at the Page source. If your
application requires one of the two PAGE ASSIGN switches to
control both Page 1 and Page 2 Assign, simply wire all Page 1
and Page 2 control bits in parallel. You may wish to leave the
knob off the unused control and cover it with one of the hole
plugs provided in the kit. If your installation requires Page 1 and
Page 2 remote control at two different locations, only three wires
are required for each PR 2 remote (Z1, Z2 & GND). As above,
you may wish to leave the knob off the unused control and cover
it with a hole plug.
The ZR 1 remote provides Zone Level and Source Selection,
allowing local control from inside the Zone. Two ZR 1 remotes
may be used (only use one in each Zone). If only one of the two
controls is used, you may wish to cover the unused control with
one of the hole plugs provided in the kit. If you require one ZR 1
remote to control both Zones, simply wire the ports in parallel.
This may be done with Program Select only, Level only or both.
If only one of the two controls is wired in parallel, the other is
still available for a second remote.
When paralleling one remote across multiple CP 64s, all
three control pins must be wired, including the shields.
Power to the CP 64 should be off until all connections are
made. It is important to ensure that the CP 64 Remote Ports are
not subjected to sustained voltages outside the range of 0 to 5
volts DC or high levels of static. Inputs are protected, however,
caution is the better part of… you know. It is a good idea to
install the wiring, connect it to the remote assemblies and then
make the final connections at the CP 64. Do not short Vr1 or
Vr2 pins to ground. These pins are current limited, however, excess heat is generated in the 5 volt supply if a short occurs. Never
subject the Vr1 or Vr2 pins to voltages above 5 volts.
Manual-5
REMOTE MOUNTING
The ZR 1 and PR 2 remote assemblies mount in a standard
U.S. electrical box with a minimum depth of 2.25". Be sure to
note the wire color of each input in order to facilitate correct
wiring to the CP 64. Connect each wire to the 5-pin connector by fully inserting it in the correct socket and tightening the
screw. Make sure wires are free of nicks and that the cable jacket
is stripped back sufficiently to allow it to lie in the electrical box
with the remote assembly inserted. Use the flat head #6 screws
supplied with the kit to mount the remote assembly and silkscreened front panel to the electrical box (see above diagram).
Note the “UP” arrow screened on the printed circuit board of
each remote (it should mount pointing up).
The silk-screened front panel metal is painted on both sides.
This allows you to custom silk-screen the panel or add your own
custom decals. Simply install the modified front panel with your
art facing out, and you are in business!
Install each knob so that the line on the knob is properly
aligned with the silk-screening on the front panel of the remote
assembly. Install any Decora plate of your choice. For a secured
installation, you may wish to leave the knobs off and use a blank
Decora plate to cover the remote after adjustment.
WIRE TYPES
Variations in wire type do not greatly affect the performance
of the remote controls. 22-gauge stranded wire with a flexible
jacket is recommended. You may use 5-conductor unshielded
remote control signal cable for shorter runs (less than 200 feet
[60 meters]), or 4-conductor (2 pair) shielded remote control
signal cable (use the shield as the ground return) for longer runs
(200 to 1000 feet [60 to 300 meters]). The type of wire required
is influenced by your installation and local electrical codes.
Rane Corporation does not provide or source cable. Please
contact your local retail or wholesale outlet, not the factory. The

RECOMMENDED CALIBRATION PROCEDURE
The CP 64 is a very versatile instrument. While this allows it to conform to the requirements of a large number of system applications, it also results in complexity. For this reason, it is very important to use an organized approach to system calibration. Once
the internal switches are set and the system is connected, take the time for proper calibration. The following is an ordered list of
system adjustments that should make calibration easy and result in optimum performance. Most important:
• Program Priority Assign is set to Off
• Ducker is Off
• Zone Limit Threshold is set to +20 dBu
• Page Zone Levels are set to minimum
• Remote Control is not selected
• Page Zone Assign is set to Both
The following procedure assumes that microphones are used for Page sources. The procedure (except for the exact wording) is the
same for other Page sources.
Make sure the POWER is off !
Control Presets:
Page settings (repeat for second page input):

…CP 64 Calibration (continued)
1. Connect the Power Supply and verify the Power indicator lights.
2. Verify Zone Level controls are set to Maximum and that you have an active source for each of the Program Inputs you intend to
use. Select each Program Input and adjust its Input Level control to be the very loudest you would ever desire.
3. Adjust the rear panel Zone Limit thresholds so that they just start to audibly reduce the output level. This ensures the level in a
Zone will never be louder than the maximum level you just set. If you wish one of the Zones to have a lower maximum loudness,
lower the Zone Limit threshold accordingly.
4. Turn the Zone Level controls down to a comfortable listening level.
5. Note that with the Paging Zone Level set to minimum, you will not hear the following Page. Speak very loudly (bark) into the
Paging Mic. Set the proper preamplifier gain by adjusting the Page Trim control (rear panel) so the Page OverLoad Indicator
(rear panel) just lights. It is important to set the gain of the pre-amp before setting the Page Detect Threshold. Repeat for second
Mic if used.
6. Speak into the Page Mic in a normal voice and adjust the Page Detect Threshold (rear panel) so the Active indicator (front panel)
lights only when you speak. If the Page Detect Threshold is set too low, the Pager may gate on due to background sound. Repeat
for second Mic if used.
7. With an active Program source playing in both Zones, speak into the Page Mic. Adjust the Zone 1 and Zone 2 Page Level controls (front panel) to provide the correct Page-to-Program mix in each zone. If the Page Detect Threshold is set too high, there
may be a delay when you start to speak. To correct, lower the Page Detect Threshold setting. If a second Page source is used,
verify that it has the same level as the first Page source (it should be close). If not, use the Page Trim control of the second Page
source to adjust its gain to match. If you change the gain of the second Page source substantially, be sure to reset the Page Detect
Threshold.
8. Set the Ducker switch to ON. With an active Program source playing, speak into the Page Mic and adjust the Ducker Depth as
required. Repeat for both Zones.
9. Set the Program Priority Assign switch as required (on rear panel). If you do not require automatic priority program override in a
zone, do not assign it. Instead, use the front panel Program Select switch to select the “P” program Input as you would any other
non-priority input.
10. If a remote control is used, select the appropriate RMT switch settings on the front panel and verify that the remotes will function correctly.
11. Adjust the Equalizers as required.
…You’re all set.
