cerasonar cs-500dsp4 - 4-Channel Installation Amplifier with DSP

The cerasonar cs-500dsp4 is a compact 4-channel installation amplifier designed for demanding AV projects requiring precision, flexibility, and reliability. It delivers 4 x 125W at 4/8 ohms or 2 x 250W in bridged mode at 8 ohms or 70/100V, making it ideal for powering installation speakers and subwoofers in multi-room systems.

Its built-in DSP offers 8 PEQ filters per channel, delay, dynamic bass boost, high-pass filtering, polarity switching, and per-channel preset selection. A built-in tone generator (sine, pink noise, white noise) allows fast system testing without external measurement tools.

Control is available via USB, LAN, RS232, RS485, and GPIO. No driver installation is required, and basic settings can be accessed via a password-protected LCD screen. Analog inputs are available as balanced and unbalanced via XLR and Phoenix connectors, with signal loop-through to other amplifiers (daisy chain).
