CP64S
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 ampliers and
the CP64S turned o 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. e 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. e
default is o.
• 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 inuenced by Zone Level, EQ or Limiter circuits.
e default is Post-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 Prior-
ity 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 control, then set the Page
DETECT THRESHOLD and nally the Page Zone LEVEL.
WEAR PARTS: is product contains no wear parts.

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 Program PRIORITY ASSIGN ZONE
switch assigns priority override to O, 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. 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 Post-VCA. Page is always avail-
able 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 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. 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 V1or V2. Do not ground
the Vr1or Vr2pins.
SETUP ADVICE
e 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. is will avoid problems and
reduce the need to increase our collective phone bills.

CP64S
COMMERCIAL PROCESSOR
Features
• Two fully independent gated Mic/Line Paging Inputs
• Paging Priority Assign
• Page Ducking
• Page / Program / Zone Expansion
• Three stereo Program Inputs
• One gated stereo Priority Program Input
• 7-Band graphic EQ for each Zone
• Servo-Locked-Limiter™ for each Zone
• Optional ZR1 Remote Zone Level/Program Select Remote
• Universal Internal Power Supply (100-240 VAC)
General Description
e CP64S is a versatile commercial preamplier designed for
use in restaurants, bars, health clubs and oces. e CP64S is
capable of serving two independent Zones. Two gated Paging
inputs and four Program inputs are provided. Ports are provided
for expansion of Page, Program or Zone signals. Four levels of
priority are supported:
• Priority Page
• Non-Priority Page
• Priority Program
• Non-Priority Program
e versatility of the CP64S allows a wide variety of system con-
gurations while providing simple and intuitive controls.
Two gated Paging Inputs capable of receiving mic or line
level input are provided. Each features independent Mic/Line
Pad, Gain Trim, detector reshold, Zone Assign and Zone
Level controls. Internally selectable phantom power is provided
for each input. Each Paging input may be summed Pre- or Post-
Zone Level control to allow setting Paging Level independent of
Zone Level. An internal Paging Priority switch allows a “master”
pager to override non-priority paging in its assigned zones, while
allowing true dual zone independent paging. If no Paging Prior-
ity is selected, the Paging inputs mix together for applications
like karaoke.
Four stereo Program inputs are provided with independent
Input Level controls. Any one of the four Program inputs may
be independently assigned in each Zone. One of the Program
inputs is a gated Priority Program input. When signal is detected
at its input, it overrides any non-priority Program selection in the
assigned Zones. e Priority detector features internal, adjustable
reshold and Release-Time controls.
e CP64S has two Zone outputs: Zone 1 is stereo: Zone 2 is
mono. Each Zone features independent:
• Level
• Program Select
• Ducker On/O
• Ducker Depth
• Servo-Locked-Limiter™
• 7 Band EQ (±12 dB)
Versatile wired remote control interface ports are provided for
Paging assignment, Zone Level and Zone Program source selec-
tion. e ZR1 Source and Volume remote control is available as
an accessory.

1PAGING INPUT Euroblock connectors may be operated balanced or unbalanced. See "CP64S Connections" on page 10. If
either page mic needs phantom power, see "Internal Adjustments" on page 9.
2PAGE 1 and PAGE 2 INPUT MIC / LINE switches select 30 dB Input Pads when set to LINE. Phantom Power (if enabled) is
disabled when LINE is selected. If either page mic needs phantom power, see "Internal Adjustments" on page 9.
PAGE 1 and PAGE 2 INPUT TRIM controls adjust Page Input preamplier 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.
PAGING INPUTS OL indicator lights when either of the Page Input preampliers comes within 3 dB of clipping, assisting the
setting of these trims.
Page 1 is set at the factory for priority over Page 2. If you want to change this, see "Internal Adjustments" on page 9.
3Four 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 ZONE switch.
4PRIORITY ASSIGN ZONE switch determines in which Zone(s) the automatic priority override is enabled. O (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.
5LIMITER 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.
6OUTPUTS feature balanced cross-coupled line drivers with a Euroblock connector for each Zone. Zone 1 is stereo. Zone 2 is
mono, and both Expand outputs are mono. When operating cross-coupled line drivers unbalanced, it is essential to ground the (–)

Internal Adjustments
ere are a number of controls inside the CP64S to congure
the system for specic applications. Access to these controls is
only required once before initial system setup. Do this before the
CP64S is installed in a rack or wired into a system. Make sure
the power cable is unplugged before removing the top cover to
gain access. Refer to the diagram below for control locations.
1 2 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 Paging Input Mic / Line pad
switch is set to LINE, Phantom Power is automatically defeated.

3Page Priority Assign 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. e non-priority
Pager may still broadcast in any Zone that the Priority Pager is
not assigned to or not currently broadcasting in. If a Page Input
is used for emergencies, set it as the Priority Pager. Set the switch
to P1 if you wish Page 1 to have priority over Page 2 (the default
setting). If you wish Page 2 to have priority over Page 1, set the
switch to P2. If NO is selected, neither Paging Input has priority
and both Pagers may be active at the same time. is allows the
Paging Inputs to mix for applications like karaoke or PA.
4 5 e Zone 1 Page and Zone 2 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 independent of the Program Level, set the switch for
that Zone to “Post.” is is the default setting, and is best 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 aected by the front panel ZONE
LEVEL control. Note the following:
• Zone Level, EQ and Limiter circuits do not aect Page signals
summed Post-VCA.
• Zone Level, EQ and Limiter circuits do aect 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:
6Priority Release Time 2 sec to 20 sec (trim pot)
Default: 12 seconds
7Priority 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 triggering 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, satellite or 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:
8Zone 1 Mode Mono/Stereo Default: Stereo
CP64S Connections
Do not connect the power cable to the CP64S until all connections
are made.
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 (maximum 12 guage). If the ground or shield wire
is left shorter, it acts as a strain relief for the other wires. Cable
with a exible 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 operate balanced or unbalanced. Expand
and Zone Outputs are driven by cross-coupled line drivers and
operate balanced or unbalanced. For both Inputs and Outputs,
wiring is the same. Balanced operation is recommended, and
necessary when wire lengths are greater than 10 feet (3 meters).
Balanced wiring is (+) to (+), (–) to (–) and shield to shield.
For unbalanced operation, we recommend using two conduc-
tor cable with shield. e cable is wired to the CP64S 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 CP64S. 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 CP64S and any other unit in
the system to have good earth or technical grounds. If a unit is
located more than 10 feet (3 meters) away from the CP64S or
is of a type that might create grounding problems, use isolation
transformers with unbalanced cable.
When operating cross-coupled line drivers unbalanced (i.e., any
CP64S Output), it is essential to ground the (–) pin.
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.
Depending on building grounding, an occasional source of
system hum is powering sources and ampliers on dierent elec-
trical circuits. Try connecting everything on the same circuit.
See the RaneNote "Sound System Interconnection" on page
19 to answer any uncertainties, especially when using unbal-
anced sources.

CP64S
COMMERCIAL PROCESSOR
Remote Controls
e CP64S 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.
ZR1 ZONE SOURCE / LEVEL REMOTE
e ZR1 remote provides Zone Level and Source Selection,
allowing local control from inside the Zone. Two ZR1 remotes
may be used (only use one in each Zone). If only one of the two
controls is used, you may cover the unused control with one of
the hole plugs provided in the kit. If you require one ZR1 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 CP64S’s, all
three control pins must be wired, including the shields.
Keep the power cable unplugged to the CP64S until all
connections are made. It is important to ensure that the CP64S
Remote Ports are not subjected to sustained voltages outside the
range of 0 to 5 volts DC or high levels of static. Inputs are pro-
tected, however, caution is the better part of… you know. It is a
good idea to install the wiring, connect it to the remote assem-
blies and then make the nal connections at the CP64S. Do not
short Vr1or Vr2pins to ground. ese pins are current limited,
however, excess heat is generated in the 5 volt supply if a short
occurs. Never subject the Vr1or Vr2pins to voltages above 5 volts.

VR1 LEVEL REMOTE
Rane provides the VR1 Volume Remote for
some applications that require a remote level
control without the program selector found in
the ZR1. It contains the same 2k RD taper pot,
and connects as shown in the ZR1 schematic.
With the front panel REMOTE switch, all
selection and level is done either on the front
panel or at the remote; never both locations.
Connecting just a VR1 to the CP64S remote
control terminals will allow level adjustment.
However without a source selector, the unit
will default to source one. If the PRIORITY /
L4 INPUT automatic switching is enabled, then the unit will
select the L4 signal when present and L1 at any other time. us
if only a jukebox (P/L4) and other line source (L1) are used, the
remote volume control will work just ne.
REMOTE MOUNTING
e ZR1 and VR1 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 CP64S. Connect each wire to the Euro 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 suciently to allow it to lie in the electrical box with the
remote assembly inserted. Use the at head #6 screws supplied
with the kit to mount the remote assembly and silk-screened

on the printed circuit board of each remote (mount it pointing
up).
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.
REMOTE PAGE ZONE ASSIGN
Euroblocks provide remote switching of Page Zone Assign for
each of the Page 1 and Page 2 inputs. Two momentary (door-
bell) switches allow push-to-talk functionality. Push both to
page in both zones. If your application requires one of the two
Page Assign switches to control both Page 1 and Page 2, simply
wire all Page 1 and Page 2 ports in parallel. Only three wires are
required for each pair of switches (Z1, Z2 & GND).
Wiring is internal pull-up, active low, switch closure to
ground, or 5 volt TTL logic.

00 = Both
WIRE TYPES
Variations in wire type do not greatly aect the performance of
the remote controls. 22-gauge stranded wire with a exible 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
inuenced 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

Recommended Calibration Procedure
e CP64S is a versatile instrument, allowing it to conform to lots of system applications. e result is complexity. For this reason, it
is important be organized in system calibration. Once the internal switches are set and the system connected, take the time for proper
calibration. is ordered list of system adjustments will make calibration easy and result in optimum performance. Most important:
• Program Priority Assign rear panel o
• Limiters rear panel +20 dBu
• Duckers front panel OFF
• Page Zone Levels front panel Min
• Remote Controls front panel not selected
• Paging Zone Assigns front panel 1&2 (both)

…CP64S Calibration (continued)
1Connect the power cord and verify the Power indicator lights.
2Verify 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.
3Adjust the rear panel Zone Limiter 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 Limiter threshold accordingly.
4Turn the Zone Level controls down to a comfortable listening level.
5Note 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 preamplier 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 reshold. Repeat for the
second Mic if it is used.
6Speak 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.
7With an active Program source playing in both Zones, speak into the Page Mic. Adjust the Zone 1 and Zone 2 Paging Level
controls (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 rst 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.
8Set 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.
9Set the Program Priority Assign Zone 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.
0If a remote control is used, select the appropriate RMT switch settings on the front panel to verify the remote functions correctly.
qAdjust the Equalizers as required.

Interconnection-1
Introduction
is note, originally written in 1985, continues to be one
of our most useful references. It’s popularity stems from
the continual and perpetual difficulty of hooking up audio
equipment without suffering through all sorts of bizarre
noises, hums, buzzes, whistles, etc.— not to mention the
extreme financial, physical and psychological price. As tech-
nology progresses it is inevitable that electronic equipment
and its wiring should be subject to constant improvement.
Many things have improved in the audio industry since
1985, but unfortunately wiring isn’t one of them. However,
finally the Audio Engineering Society (AES) has issued a
standards document for interconnection of pro audio equip-
ment. It is AES48, titled “AES48-2005: AES standard on
interconnections —Grounding and EMC practices — Shields
of connectors in audio equipment containing active circuitry.”
Rane’s policy is to accommodate rather than dictate.
However, this document contains suggestions for external
wiring changes that should ideally only be implemented by
trained technical personnel. Safety regulations require that
all original grounding means provided from the factory be
left intact for safe operation. No guarantee of responsibility
for incidental or consequential damages can be provided. (In
other words, don’t modify cables, or try your own version of
grounding unless you really understand exactly what type of
output and input you have to connect.)

SOUND SYSTEM INTERCONNECTION

Interconnection-2
Ground Loops
Almost all cases of noise can be traced directly to ground
loops, grounding or lack thereof. It is important to under-
stand the mechanism that causes grounding noise in order
to effectively eliminate it. Each component of a sound
system produces its own ground internally. is ground is
usually called the audio signal ground. Connecting devices
together with the interconnecting cables can tie the signal
grounds of the two units together in one place through
the conductors in the cable. Ground loops occur when the
grounds of the two units are also tied together in another
place: via the third wire in the line cord, by tying the metal
chassis together through the rack rails, etc. ese situations
create a circuit through which current may flow in a closed
“loop” from one unit’s ground out to a second unit and back
to the first. It is not simply the presence of this current that
creates the hum—it is when this current flows through a
unit’s audio signal ground that creates the hum. In fact, even
without a ground loop, a little noise current always flows
through every interconnecting cable (i.e., it is impossible to
eliminate these currents entirely). e mere presence of this
ground loop current is no cause for alarm if your system
uses properly implemented and completely balanced inter-
connects, which are excellent at rejecting ground loop and
other noise currents. Balanced interconnect was developed
to be immune to these noise currents, which can never be
entirely eliminated. What makes a ground loop current an-
noying is when the audio signal is affected. Unfortunately,
many manufacturers of balanced audio equipment design
the internal grounding system improperly, thus creating bal-
anced equipment that is not immune to the cabling’s noise
currents. is is one reason for the bad reputation some-
times given to balanced interconnect.
A second reason for balanced interconnect’s bad reputa-
tion comes from those who think connecting unbalanced
equipment into “superior” balanced equipment should
improve things. Sorry. Balanced interconnect is not compat-
ible with unbalanced. e small physical nature and short
cable runs of completely unbalanced systems (home audio)
also contain these ground loop noise currents. However, the
currents in unbalanced systems never get large enough to
affect the audio to the point where it is a nuisance. Mixing
balanced and unbalanced equipment, however, is an entirely
different story, since balanced and unbalanced interconnect
are truly not compatible. e rest of this note shows several
recommended implementations for all of these interconnec-
tion schemes.
e potential or voltage which pushes these noise cur-
rents through the circuit is developed between the indepen-
dent grounds of the two or more units in the system. e
impedance of this circuit is low, and even though the voltage
is low, the current is high, thanks to Mr. Ohm, without
whose help we wouldn’t have these problems. It would take
a very high resolution ohm meter to measure the impedance
of the steel chassis or the rack rails. We’re talking thou-
sandths of an ohm. So trying to measure this stuff won’t
necessarily help you. We just thought we’d warn you.
The Absolute Best Right Way To Do It
e method specified by AES48 is to use balanced lines and
tie the cable shield to the metal chassis (right where it enters
the chassis) at both ends of the cable.
A balanced line requires three separate conductors, two
of which are signal (+ and –) and one shield (see Figure 1a).
e shield serves to guard the sensitive audio lines from
interference. Only by using balanced line interconnects can
you guarantee (yes, guarantee) hum-free results. Always use
twisted pair cable. Chassis tying the shield at each end also
guarantees the best possible protection from RFI [radio fre-
quency interference] and other noises [neon signs, lighting
dimmers].
Neil Muncy1, an electroacoustic consultant and seasoned
veteran of years of successful system design, chairs the AES
Figure 1a. The right way to do it.
