Owner‘s Manual 5
1 Introduction
1.1 Welcome
Thank you for choosing an Electro-Voice CPS series amplifier. Please take time to consult this manual so that you can
understand all the features built into your Electro-Voice amplifier and fully utilize all its performance capabilities.
1.2 Unpacking and Inspection
Carefully open the packaging and take out the power amplifier. Inspect the power amp’s enclosure for damages that might
have happened during transportation. Each amplifier is examined and tested in detail before leaving the manufacturing site to
ensure that it arrives in perfect condition at your place. Please inform the transport company immediately, if the power
amplifier shows any damage. Being the addressee, you are the only person who can claim damages in transit. Keep the
cardboard box and all packaging materials for inspection by the transport company.
Keeping the cardboard box including all packing materials is also recommended, if the power amplifier shows no external
damages.
When shipping the power amp, make sure to always use its original box and packaging materials. Packing
the power amplifier like it was packed by the manufacturer guarantees optimum protection from transport damage.

1.4 Features and Description
Electro-Voice CONTRACTOR PRECISION SERIES Series amplifiers offer a package of reliable high output power, high
efficiency and legendary pro audio performance. They are the premium choice as system drive for a variety of Electro-Voice‘s
installation loudspeakers like e.g. EVI, FRi, FRX or Variplex families. Their comprehensive protection system includes circuitry
against overheating, overload, short circuit, HF and DC as well as back-EMF and inrush current. Loudspeakers are protected
by turn-on-delay relays.
1.5 Responsibility of the User
Speaker System Damage
CPS power amps provide extremely high power output that might be dangerous for human beings as well as for the
connected speaker systems. High output voltages can damage or even destroy the connected speaker systems, especially,
when the CPS amplifier is operated in bridged mode. Prior to connecting any loudspeakers, make sure to check the speaker
system’s specifications for continuous and peak power handling capacities. Even if amplification has been reduced through
lowering the input level controls on the amplifier’s front panel, it is still possible to achieve full power output with a sufficiently
high input signal.
Danger at the Loudspeaker/Power Outputs
CPS amplifiers are capable of producing dangerously high voltage output that is present at the output connectors. To protect
yourself from electric shock, do not touch any blank speaker cables during operation of the power amp.
CAUTION:
Do not ship the power amp in any other but its original packaging.
