General Description:  
Power Bandwith (THD = 1% , 10 Hz - 60 kHz  
ref.1kHz, half power @ 4 Ohms):  
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 turn-  
on 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.
