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 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.
