General Description:
The Electro-Voice® CPS2.11 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 CPS2.11 is state-of-the art and
fulfills the highest sound expectations in demanding applications
from concert sound to theater. The CPS2.11 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
CPS2.11 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 CPS2.11 will not exceed
a THD of 1% up to an input signal of +21dBu. Detented 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 CPS2.11 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.
