Product Information

Prestel VCS-AB6 Digital Audio Processor

The Prestel VCS-AB6 is a digital audio processor that provides advanced audio processing capabilities. It features embedded architecture, precise volume control, and high efficiency for a safe, stable, and reliable system. The processor integrates new generation digital audio technologies such as automatic noise suppression (ANS), automatic gain control (AGC), automatic echo cancellation (AEC), automatic equalization, intelligent microphone mixing, and anti-reverberation. It supports up to 6 cascade microphone inputs and 4-channel line inputs, as well as extended wireless microphone, 4-channel line output, USB audio input, and output. With support for standard POE and digital microphone power supply, RJ45, USB, and line audio interface connections, the processor ensures plug and play functionality, simple engineering wiring, long distance transmission, and strong anti-interference ability.
