CPS - SERIES

POWER

AMPLIFIERS

The CPS Series is a high performance line of amplifiers
with innovative protection/safety features with an
unmatched dynamic range capability that exceeds the
unique usage demands for fixed-installation applications.
With its 5-way protection/safety system, the CPS series
ensures the most reliable operation favored by sound
contractors in all sound reinforcement applications.

5-way Protection/Safety System

With the unique needs of the fixed-installation customer in
mind, EV has developed and manufactured the CPS Series
of power amplifiers that will satisfy even the most
demanding applications.The CPS Series 5-way protection
system was designed to protect both the amplifier and the
speaker from damage resulting from line shorts, thermal
overload, power surges, signal degradation and signal
overload.This unique capability gives the CPS series the
ability to function reliably in the challenging conditions
encountered in fixed-installation sound systems.

Superior Dynamic Range

Given the multitude of building configurations and sound
reinforcement challenges, EV has taken the uncertainty out of
performance and reliability with the new CPS Series of
power amplifiers.The CPS Series achieves it’s outstanding
dynamic range through the use of our unique Nonlinear
Signal monitor.This feature limits amplifier distortion to less
than 1 percent, eliminating "hard-edged" clipping which can
destroy most speaker systems.

The amplifier’s power supply is specifically designed to
deliver high peak signals. Since live music and voice signals
usually contain very high peak transients compared to the
average signal level, the CPS Series amplifiers have a burst
signal output capability "headroom" in excess of 130% over
their average continuous rating.

5-way Protection/Safety System

• Line Voltage Variation Monitor — Prevents damage to both the amplifier and
speakers caused by unexpected surges,“brown-outs” or shorts in line voltage.

•

3-Stage and 4-Stage Front-to-Rear Cooling Fan System with Over-Temperature
Protection

— Quiet operation with greater cooling efficiency with added

transformer and heat sink monitors to ensure safe operating temperature.

•

RF and HF Protection — Protects speakers against damaging, inaudible high
frequency signals.

•

Nonlinear Signal Monitor (dynamic limiter) — Limits amplifier distortion to under
1 percent to eliminate “hard-edged” clipping which seriously damages woofer and
horn drivers.

•

Excessive Back-EMF Monitor — Eliminates amplifier damage from reverse current
flow back into amplifier due to speaker failure.
