Cerasonar CS-500DSP4 V2 Audio amplifier

4-Channel DSP Amplifier – Engineered for the Complete cerasonar System The cerasonar cs-500dsp4 has been developed specifically for the cerasonar loudspeaker portfolio, combining DSP processing, power amplification and loudspeaker protection within a single compact platform.‎ As the recommended amplifier for the majority of cerasonar installations, it forms the heart of complete invisible audio systems for residential, hospitality and commercial applications.‎ Using the dedicated cerasonar factory DSP presets, each loudspeaker is automatically optimised for its intended application.‎ The presets refine tonal balance, compensate for the acoustic characteristics of invisible loudspeakers and activate the proprietary Dynamic Bass Enhancement, which intelligently increases low-frequency output at low and medium listening levels while maintaining reliable loudspeaker protection.‎ When operated with the appropriate factory preset, no additional cerasonar Protection Unit is required.‎ Each amplifier channel can be assigned its own factory DSP preset, allowing different cerasonar loudspeakers and subwoofers to be combined on a single amplifier without compromising system optimisation.‎ To simplify installation even further, the cs-500dsp4 can be supplied with all required factory presets already loaded.‎ Simply specify the loudspeaker configuration when ordering, and the amplifier will be delivered pre-configured and clearly labelled, significantly reducing commissioning time on site.‎ The integrated DSP provides comprehensive system configuration including parametric equalisers, crossover filters, delay adjustment and polarity control.‎ This allows loudspeakers and subwoofers to be perfectly aligned while providing the flexibility required for stereo systems, multi-room installations and distributed 70/100V audio systems.‎ Delivering 4 × 125 W into 4 or 8 Ohms, with bridge operation supporting 250 W, as well as 70/100V operation, the cs-500dsp4 offers exceptional flexibility for both low-impedance and distributed audio applications.‎ The integrated audio pass-through function allows multiple amplifiers to be connected in a simple daisy-chain configuration, making it particularly suitable for larger multi-room installations.‎ Configuration is performed conveniently through the integrated web interface, allowing the amplifier to be accessed via any modern web browser without additional software or drivers.‎ For system integration, the amplifier provides an open API, enabling seamless communication with third-party control systems and building automation platforms.‎ Technical specifications: • Amplifier power output: 4 × 125 W @ 4/8 Ohm; 2 × 250 W @ 8 Ohm bridged; 2 × 250 W @ 70/100 V • Maximum input sensitivity: 1 V • DSP: 28-/56-bit, 50 MIPS; delay; Dynamic Bass Enhancement; polarity; high-pass filter; 8 DSP filters per channel; 4 × 4 input matrix; power limiter; preset selectable per channel • Network: 10/100M LAN • Input voltage: 115 V or 230 V, automatic • Dimensions: 215 × 44 × 240 mm • Weight: 2 kg Further info from manufacturer on CS-500DSP4 V2 Cerasonar
