The Electro-Voice CPS4.5 power amplifier offers four independent Class-D VLD amp blocks, each capable of delivering up to 500 Watts into Low-Z or High-Z loads. Per default, each channel can be configured individually for max. power output into either 2 Ω, 4 Ω, 70V- or 100V-networks without involvement of any output transformers. Being designed for professional audio installation market, special care was taken for long term cost of ownership parameters: In addition to remarkably low current consumption and heat dissipation, the CPS4.5 provides remote standby switching with just 5 Watts consumption in standby mode.
An optional remote control module RCM-810 provides control and supervision features via IRIS-Net, including monitoring of amplifier status and real time load supervision. In addition, via RCM-810 the Variable Load Drive characteristics can be set for max. power output into any load between 2 Ω and 10 Ω, in steps of 0.1 Ω.
