Electro-Voice CPS4.10
Power Amplifier, 4 Channel 4x1000W @ 2/4ohms


This four-channel CPS amplifier from Electro-Voice features groundbreaking Class-D technology for maximum amp efficiency and minimized heat dissipation in 19-inch racks.

Each channel individually provides transformerless, switchable output characteristics, which enable specific channels to achieve maximum drive. Power into 2 Ohms, 4 Ohms, 70V, or 100V line – no transformers are required. In Hi-Z operation (70V or 100V), a 50 Hz high-pass filter (HPF) provides protection against loudspeaker transformer saturation. Additionally, amplifier channels can be bridged in pairs for double output power.

Each contractor-friendly, multi-channel CPS amplifier also features Phoenix-type connectors for inputs and outputs, pre-programmable power-on delay, easy power-on remote via contact closure, and rear level controls.

A module slot for the RCM-810 remote control module provides control network functionality, allowing for remote system diagnostics and control via IRIS-Net software. In addition, using the RCM-810’s Variable Load Drive feature can tailor the amplifier’s output power to match every load from 2 Ohms up to 10 Ohms in steps of 0.1 Ohms.
