The Electro-Voice CPS4.5 amplifier offers four independent Class-D Variable Load Drive (VLD) amplifier blocks, each one 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.
