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. 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 Post­VCA. 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 compat­ible (0 to 5 VDC). e 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.
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 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. e 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 reshold. Note that a Page is always Active when its Page
Detect reshold 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. is 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. ese 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. e 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). is 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. ese circuits are true voltage limiters with a ratio
of 15:1. e 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. ree are non-priority Inputs. e 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. e 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 indica-
tor. e range is -∞ (on) to +4 dBu.
e 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. e range is 30 dB to 60 dB.
PAGE 1 and PAGE 2 INPUT Euroblock connector provides access to the two balanced instrumentation Paging amplifiers. ese
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.

INTERNAL ADJUSTMENTS
ere 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.
ere 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 phan tom 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.
-
e Page Priority switch allows you to select one of the Page Inputs as a Priority Page Input. e 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. is 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.
e Z1 Page and Z2 Page switches allow you to sum Page signals with Program signals “Pre” (before) or “Post” (after) the VCA. e VCA is used for Zone Level control and Limiting. erefore, if you require the Page Level to be controlled indepen- dent of the Program Level, set the switch for that Zone to “Post.” is 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
Manual-4
Page 7
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.
ere are two internal controls related to the Program Priority
detector:
• Priority Release Time 2 sec to 20 sec (trim pot)
Default: 12 seconds
• Priority reshold -∞ to -35 dBu (trim pot)
Default: -50 dBu
e default settings for the Program Priority detector are chosen for most applications. Detector reshold settings lower than the default setting of -50 dBu are prone to false trigger ing unless the source is very quiet. If a source is noisy, you may wish to set the threshold higher to prevent false triggering. e 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.
ere 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 conduc- tor cable with shield. e 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
e four stereo Program Inputs connect to RCA jacks. ese Inputs are unbalanced. e 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
e 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.
e 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.
e 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. is 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. ese 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.

e 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).
e silk-screened front panel metal is painted on both sides. is 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]). e 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. e following is a short list of suitable cable types:

RECOMMENDED CALIBRATION PROCEDURE
e 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. e 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 reshold is set to +20 dBu
• Page Zone Levels are set to minimum
• Remote Control is not selected
• Page Zone Assign is set to Both
e following procedure assumes that microphones are used for Page sources. e 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):
• Input Pad Mic/Line as required
• Input gain trim Center (12:00)

…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. is 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 (rear panel) just lights. It is important to set the gain of the pre-amp before setting the Page Detect reshold. Repeat for second Mic if used.
6. Speak into the Page Mic in a normal voice and adjust the Page Detect reshold (rear panel) so the Active indicator (front panel)
lights only when you speak. If the Page Detect reshold is set too low, the Pager may gate on due to background sound. Repeat for second Mic if used.
OverLoad Indicator
7. With an active Program source playing in both Zones, speak into the Page Mic. Adjust the Zone 1 and Zone 2
trols (front panel) to provide the correct Page-to-Program mix in each zone. If the Page Detect reshold is set too high, there may be a delay when you start to speak. To correct, lower the Page Detect reshold 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 reshold.
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 “ 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 func
tion correctly.
11. Adjust the Equalizers as required.
