500 W Per Channel 4-channel Amplifier
|
The Electro-Voice Contractor Precision Series amplifiers combine top-quality performance and reliability with innovative designs perfectly tailored to the needs of professional sound installation. Available in 2 RU configurations of up to eight channels, CPS 4.5 amps are compact and efficient to operate, with every detail thought through from the contractor's point of view. For fast installation and setup, CPS 4.5 model features Phoenix-type input and output connectors, programmable power-on delay, remote power-on/off, rear-mounted attenuators, and switchable high-pass filters.
For worry-free dependability, there's full protection against hazards such as excessive heat, overloads, shorts, DC, back-EMF, and inrush current. And for the ultimate in system control and supervision, the optional RCM-810 module enables the inclusion of CPS amps in IRISNet networks of up to 250 devices. Offering exceptional ease, flexibility, and audio performance, CPS series is the ideal installation solution for cinema, club sound, commercial sound/life safety, and performance and sports venues.
The new four- and eight-channel CPS amplifiers from Electro- Voice feature 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-810s Variable Load Drive feature can tailor the amplifiers output power to match every load from 2 Ohms up to 10 Ohms in steps of 0.1 Ohms.
