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.
