General Description:

The Electro-Voice® CPS2.8 is from the Contractor Precision

Series of professional amplifiers. The high efficient Class-H
design reduces the power dissipation significantly and allows
for more amplifier channels and output power in a given rack
space. The audio performance of the CPS2.8 is state-of-the
art and fulfills the highest sound expectations in demanding
applications from concert sound to theater. The CPS2.8
features the same complete protection package as all EV
Precision Series amplifiers. Protection against: excessive HF,
DC fault , high temperature, and Back-EMF as well as turn­on delay, peak current and inrush current limiters. In addition
to the rated output power the CPS2.8 provides up to 30%
percent headroom for a wide dynamic range on music signals.
The onboard dynamic limiter ensures that the output clipping
of the CPS2.8 will not exceed a THD of 1% up to an input
signal of +21dBu. Detend level controls on the rear panel
provide precise (1dB-detend) and repeatable settings. Front
panel LEDs indicate signal present, 0 dB, and limit. Female
XLRs and Phoenix type connectors for inputs and barrier
strips for outputs provide an easy rack wiring.The power on/
off function of the CPS2.8 can be remote controlled via a
24V DC source. Optional x-over cards for biamp operation
(e.g. a 2-way cinema system) can be retrofitted.
