CH1-SOUND

CompactPCI  Six Channel Audio Processor

High Performance Recording and Playback


The CH1-SOUND is a high performance audio accelerator add-in card for CompactPCI® systems. The 3U board exceeds the Microsoft® PC 99 audio performance specifications and complies with the Intel® AC '97 spec.

The CH1-SOUND provides a complete suite of analog and digital I/O connections. The board contains three stereo outputs for front L/R, surround L/R and center/low frequency speakers. The optical S/PDIF interface is compatible with consumer devices such as stereo receivers and MiniDisc recorders.



The sound card features a 420MIPs high speed DSP audio processor, and two audio codecs. The codecs include stereo 20-bit DACs and stereo 18-bit ADCs, allowing for recording, mixing and playback of voice and music at the highest quality level.

The CH1-SOUND is a perfect solution to industrial range CPCI systems with need for high performance audio I/O, e.g. passenger information systems or computer telephony applications.
