DESCRIPTION
Congratulations! With buying a Electro-Voice CP-SERIES power amplifi er you have chosen an appli-
ance that employs most advanced technology.
CP-Series power amps combine outstanding audio performance, highest reliability and operational
safety.
The audio performance of CP power amps are simply extraordinary. Optimised power supply units
employing low-leakage toroidal transformers and the consistent use of Class-H technology provide extensive headroom far above the stated nominal output. At the same time this contributes to a reduction
in weight and power dissipation.
The CP1800/CP2200 is designed in Class-H technology (CP1200 Class-AB), i.e. the power amp provides
extremely fast, signal-dependent operating voltage switching, which results in doubling the regular
supply voltage when needed. Compared to Class-AB power amps, Class-H power amps generate by
far less power dissipation at identical output. Consequently, reduced leakage power or dissipation is
synonymous to less waste heat – energy is used more effi ciently. As a result, installing Class-H power
amps within rack shelf systems is possible with less space between appliances. In addition to that and
despite offering identical output, power consumption is a lot less than in Class-AB operation.
Electro-Voice CP-SERIES power amps have been designed to fulfi l even the most demanding
requirements of touring applications. CP-Series amps are protected against thermal and electrical
overload, short circuit and the occurrence of HF/DC at the outputs. Back-EMF-Protection eliminates
the risk of the output transistors being damaged by electrical energy back-feed. The power outputs are
switched via relay with a time delay during soft-start. An inrush current limiter prevents mains fuses from
blowing.
Mechanical construction and workmanship also comply with the highest precision manufacturing
standards. The rigid sheet steel chassis even resists the most wearing tour operation. Two three-speed
high performance fans (off/slow/fast) guarantee outstanding thermal stability at absolute low running
noise. The ventilation is directed front-to-rear allowing trouble-free operation even in smaller amp-racks.
The electronically balanced inputs are carried out via XLR-type connectors. Direct-Outs for through
connecting the audio signal are also provided via XLRM-type connectors. Input Routing allows selecting
DUAL (stereo) or PARALLEL (monaural) operation mode. By means of the separate BRIDGED OUTconnector and a Bridged Mode-switch, switching to „Mono Bridged“ operation is truly uncomplicated
as well. The recessed mounted dB-scaled level controls ensure reliable protection against mechanical
damage. These particularly precise, secure to operate detent-potentiometers are located on the front
panel. CP-Series power amps provide the opportunity for retrofi tting an internal analogue signal
processor board with x-over and fi lter functions.
The easily readable LED display provides a quick overview of the power amp’s current operational
status. The power outputs CHANNEL A, CHANNEL B and BRIDGED OUT are carried out as extremely
durable SPEAKON-type connectors. Also located on the rear panel is a Ground-lift switch, which helps
eliminating ground-noise loops by separating the power amp’s enclosure from the circuit ground. In
normal operation, all CP-Series power amps are capable of driving loads as low as 2ohms. In MonoBridged mode the allowable minimum load is 4ohms.
This owner’s manual outlines and explains several other features of your CP-Series power amplifi er.
Please, make sure to carefully read all of it and mind the instructions.

DESCRIPTION
UNPACKING & WARRANTY
Carefully open t he packaging and take out the power amplifi er. Next to the power amplifi er itself, the
package also includes this owner’s manual, a mains cord and the warranty certifi cate. Keep the original
invoice, which states the purchase/delivery date together with the warranty certifi cate at a safe place.
INSTALLATION NOTES
Generally, installing or mounting power amps should be carried out in a way that guarantees continuously unopposed front-to-rear air circulation. Installation of appliances with opposite air circulation within
one cabinet or closed rack shelf system is not recommended. When including an appliance in a closed
cabinet or rack shelf system make sure to provide suffi cient ventilation. Leave a gap of at least 60mm x 330mm (up to the cabinet’s top ventilation louvers) for air circulation between the rear of the power
amplifi er and the cabinet’s/rack’s rear inner wall. Make sure to leave at least 100mm of space above the
cabinet or rack shelf system. Since temperatures inside of the cabinet or rack shelf system can easily
rise up to 40°C during operation, bearing in mind the maximally allowable environmental temperature
during operation for all other appliances installed in the same rack shelf system is mandatory (also refer
to “MAINS OPERATION AND RESULTING TEMPERATURE”).
Caution: For trouble-free operation exceeding the maximally allowable environmental tem-
perature of +40°C is not permissible.
The use of installation rails or optionally available “rear-rack-mount” rails is strongly recommended when
installing the appliance in a rack shelf system or cabinet to prevent the front panel from bending.
The power amplifi er has to be protected against: dripping or splashing water, direct sunlight, high tem-
peratures or direct infl uence of heat sources, high humidity, extensive dust and vibrations.
Condensation on internal parts may occur when transporting the power amplifi er from a cold into a
warmer environment. In that case operation is only permissible after the appliance has gained the
new temperature (after approximately one hour). If foreign objects or liquids have entered the power
amplifi er’s enclosure make sure to instantly separate the appliance from the mains power and contact
an authorised service centre for inspection before continuing operation.

INPUT A / INPUT B The inputs INPUT A & INPUT B of the CP series are electronically
balanced. The voltage gain of all models is set to 32 dB (constant
gain). This results however in different input sensitivities for the different models (see table), but the level adjustment of active crossovers or signal processors in multi-way systems is much easier.
Power amplifi ers with different output power can be changed with-
out consideration, the crossovers have not to be adjusted due to
the constant amplifi cation of the whole unit line. If external voltage
limiters are used, they should be set to the used power class with

consideration of the connected speaker systems. The XLR-type
connectors OUTPUT A & OUTPUT B are prepared for „through-
connecting“ input signals to additional external power amps. The
input signal is directly routed to these output connectors. There
are no repeaters or other electronic components within that signal
Although having XLR-type output connectors, some mixing console models provide unbalanced
output connection only. When using mixers with unbalanced outputs, bridging PIN1 and PIN3
of the power amp’s input connectors or leaving PIN3 of the cable’s plugs unconnected is
necessary. Otherwise, when feeding in unbalanced audio signals via PIN3 (b, -, „cold“) and PIN2
(a, +, „hot“), strange humming and HF-interference may occur, which very likely will damage the
power amplifi er and/or the connected speaker cabinets.
NF-CONNECTION CORDS
Choosing high-quality balanced cables (two conductors for the audio signal plus separate shielding mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting
unbalanced cables to the power amplifi er inputs is possible as well, using balanced cables is always
preferable. A great number of today’s audio appliances employ balanced outputs. With balanced cabling, the shield connects all metal enclosure parts and therefore effi ciently eliminates the introduction
of external interference – mostly noise and hum.
XLR-type connector pin-assignment
XLR (male) XLR (female)
The input connectors of channel A and channel B are electrically connected
in parallel when the selector switch is set to PARALLEL. However, individually
controlling the volume of both channels is still possible via the corresponding level
controls A and B.
DUAL
If the selector switch is set to DUAL, the audio signals of channels A and B are
independently amplifi ed.

REAR PANEL
POWER AMP OUTPUT CONNECTORS
Power amp output connection for the two channels A
(left) and B (right) is provided via SPEAKON-type output
connectors.
A plastic cover to prevent inadvertent erroneous
connection protects the BRIDGED OUT connector. Make
sure to remove the cover only when actually operating the
power amplifi er in Bridged-Mode.
CAUTION!
Pins 2+/2- of the CHANNEL A SPEAKON output, which
normally are not in use, are also connected to output B to
ensure comfortable connection of 2-way speaker cabinets
(e.g in Bi-Amping Mode) when using 4-wire Speakon
cables.
To prevent short-circuit and/or to protect your speaker systems from being damaged when connecting
the cabinets, please make sure to mind the Low- and High channels’ specifi c pin-assignments!
If, for example, the subwoofer audio signal is used to feed a tweeter, it is more than likely that this will
instantly destroy the HF-driver’s coil.
WARNING:
The speaker output terminals are marked with a symbol “ ”, which signifi es that these
terminals are hazardous live and present a risk of electric shock to the user.
BRIDGED MODE
With the BRIDGED-MODE switch being engaged, using the channel A input
for audio signal feed is mandatory, since input B provides no function. While
the amplifi er of channel A operates as usual, the audio signal is internally inverted and routed to the amplifi er of channel B. Both amps – A and B – now work in push-pull operation to provide doubled output voltage at the
BRIDGED-OUT connector.
The regular output voltage of each amplifi er channel A / B is still present at the corresponding output
connector CHANNEL A or CHANNEL B. However, using these signals is not recommendable because
of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads of 2ohms
connected is not allowable.
CAUTION: Extremely high voltages might be present at the BRIDGED OUT connector during
Bridged-Mode operation. The connected loudspeaker systems have to be capable of handling
such high voltages. Please make sure that power handling specifi cations as stated in the docu-
mentation supplied with your speaker systems match the specifi cations of the power amplifi er.
GROUND-LIFT SWITCH
The ground-lift switch allows eliminating noise loops. If the power amplifi er is operated together with other equipment in a 19“ rack-shelf, setting the switch
to its GROUNDED position is recommended. If the power amplifi er is operatedtogether with appliances with differing ground potentials, set the switch to its
UNGROUNDED position.
MAINS INPUT
Under normal circumstances, the mains fuse only blows in case of fault.
Replacing the fuse is only permissible when using a new fuse of the same
type with identical amperage, voltage and blow characteristics. If the mains
fuse blows more often, please contact an authorized service centre.
The high-performance mains cord supplied with your power amplifi er complies to applicable safety regulations, plus that its diameter corresponds to the power
amp’s power output capacity. Make sure to use the supplied mains cord for connecting the power amp
to the mains. Using mains cords with smaller diameters results in higher leakage and consequently reduced maximum power output capacity.
At 100V and 120V units the mains fuse is installed internally. This is fore safety reasons. In case of a
blown mains fuse please contact a qualifi ed service personnel for servicing.

MAINS OPERATION & RESULTING
MAINS OPERATION & RESULTING TEMPERATURE
The following tables allow determining power supply and cabling requirements.
The power drawn from the mains network is converted into output power to feed the connected
loudspeaker systems and into heat. The difference between power consumption and dispensed power
is called power dissipation (Pd). The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures. The following table is meant
as auxiliary means for calculating temperatures inside of a rack-shelf system/cabinet and the ventilation
efforts necessary.
The column „Pd“ lists the leakage power in relation to different operational states. The column „BTU/
hr“ lists the dispensed heat amount per hour.
