AUDAC CEP408 Four-Channel Power Amplifier 4 x 80W @ 8Ω

The AUDAC CEP408 is a professional four-channel power amplifier delivering robust and reliable audio amplification for commercial and residential installations. With 4 x 80 W RMS at 8 Ω, it provides ample power for multi-zone audio systems, while its Class AB design ensures high-quality sound reproduction with low distortion. The amplifier features balanced XLR inputs and screw terminal outputs, making it easy to integrate into any fixed installation. Its 2U rack-mountable chassis and forced convection cooling guarantee stable operation even under demanding conditions.

Advantages

The CEP408 offers exceptional flexibility with four independent channels, each capable of driving 8 Ω or 4 Ω loads. The bridge mode allows combining two channels into a single high-power output of 240 W at 8 Ω, perfect for subwoofers or large full-range speakers. Comprehensive protection circuits, including DC, short circuit, overheating, overload, and clip limiter, safeguard both the amplifier and connected speakers. The high damping factor (>200) ensures tight bass control, while the signal-to-noise ratio of >95 dB keeps the background noise inaudible.
