General Description:  
Voltage Gain ref. 1 kHz:  
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 ampli-  
fiers. Protection against: excessive HF, DC fault, high tempera-  
ture, 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.
