cerasonar cs-500dsp4 v2 - 4-channel Class D power amplifier with DSP, 4x125W, bridged operation and 100V/70V line, passive cooling, browser control

The cerasonar cs-500dsp4 v2 is a compact, 4-channel Class D amplifier with a DSP processor that combines signal processing, amplification, and speaker protection in one device. The manufacturer recommends it for most installations with cerasonar invisible speakers in homes, hotels, restaurants, and commercial spaces. Factory presets for cerasonar speakers ensure optimal sound in any room: they correct tonal balance, compensate for the acoustics of invisible speaker installations, and protect them from overload. The preset is selected separately for each output, so one amplifier can power different speakers and subwoofers. The amplifier delivers 4x125W at 4Ω or 8Ω, 2x250W in bridged mode at 8Ω, or 2x250W in 70V or 100V lines, making it suitable for stereo, multiroom, and extensive zone installations. Passive cooling ensures completely silent operation, so the amplifier can be placed even where every noise is heard. Four balanced inputs with a 4x4 matrix allow for flexible routing of sources to outputs, and RCA adapters included enable connection to two stereo RCA sources. Through outputs facilitate connecting multiple amplifiers in larger zones. Configuration is done in a browser on any device in the LAN network, without additional software. Available features include a parametric equalizer, filters, tone control, power limiter, delay, and polarity. An open API and Control4 support allow the amplifier to be integrated into building automation systems, while automatic standby or 12V triggering reduces energy consumption. The amplifier can be mounted in a 19" rack, one or two in a 1U space.
