Electro Voice CPS4.5 4-Channel Power Amplifier, 4 x 500W into 2, or 4 Ohms, or 70V/100V Direct Drive
Description Electro Voice CPS4.5 4-Channel Power Amplifier, 4 x 500W into 2, or 4 Ohms, or 70V/100V Direct Drive The Electro Voice CPS4.5 is a four-channel amplifier that is designed with groundbreaking features, it comes with a Class-D technology for the ultimate amplifier efficiency. Powering up into 2 Ohms, 4 Ohms, 70V or 100V lines are all made possible in this device, and it is not requiring a transformer to do that. In addition to that, the amplifier channels is able to be bridged in pairs for double output power. A module slot for the optional RCM-810 remote control module is providing the control network functionality, that allows the remote system diagnostics using the IRIS-Net software as well as Variable Load Drive (VLD). Features Four channels in one compact rack-efficient unit 500 W per channel 70/100 V operation for distributed systems Class-D design for optimum efficiency Slot for optional RCM-810 module, allowing IRIS-Net control and monitoring IRIS-Net selection of each channel's impedance (2-10 Ω in 0.1 Ω steps) Rear-mounted attenuators Switchable 50 Hz high-pass filter (Hi-Z mode) Complete protection: thermal, overload, shorts, HF, DC, back-EMF, inrush current Phoenix-type input and output connections Remote power-on/off contact Programmable power-on delay settings Front-to-rear fans Specifications Weight Net 11.1kg (24.47 lbs) Depth 421.5mm (16.59") Width 482.6mm (19") Height 88.1mm (3.47") Amplifier Gain 32 dB (Lo-Z), 33 dB (70V), 36dB ((100V)) Analog Inputs 4, electronically balanced, Phoenix-type Audio Network No CAN Bus Interface Optional (RCM-810 card) Continuous Rated Power (1 kHz, THD 1%) 100v 500Watts Continuous Rated Power (1 kHz, THD 1%) 2Ω 500Watts Continuous Rated Power (1 kHz, THD 1%) 4Ω 500Watts Continuous Rated Power (1 kHz, THD 1%) 70v 500Watts Continuous Rated Power (1 kHz, THD 1%) 8Ω 250Watts Continuous Rated Power (20-20 kHz, THD<0,2%) 100v 450Watts Continuous Rated Power (20-20 kHz, THD<0,2%) 4Ω 450Watts Continuous Rated Power (20-20 kHz, THD<0,2%) 70v 450Watts Continuous Rated Power (20-20 kHz, THD<0,2%) 8Ω 225Watts Cooling Front-to-Rear, continuously variable fans DIM 30 0.02% Electronics Type Amplifier Frequency Response (-3 dB) 15 Hz-30 kHz Impedance 2/4/8/8 VLD/70 V/100VΩ Input Impedance (Balanced) 20kΩ Input Sensitivity 0 dBu (.775V)-2ω, +3 dBu (1.1V)-4/8ω, +6 dBu (1.55) 70V/100V Intermodulation Distortion (SMPTE) 0.05% Mains Voltage 220 - 240 V, 50 - 60 Hz or 120 V, 50 - 60 Hz, 50 - 60 Hz Maximum Bridged Output 4Ω 1000Watts Maximum Bridged Output 8Ω 1000Watts Maximum Input Voltage +22 (9.76 Vrms) Network Control (IRIS-Net) Optional (RCM-810 card) Signal-to-Noise Ratio (A-weighted) 100dB Slew Rate 28V/µs Topology Class-D Total Harmonic Distortion 0.05% Variable Load Drive (VLD) Yes
