PCI SOUND CARD INTEGRATES GPIO AND RS422. 

Newcastle, Delaware - February 1, 2000.  AudioScience Inc., a manufacturer of digital audio products for the broadcast industry, has announced the ASI4336 PCI broadcast audio adapter. This adapter features multieam MPEG audio record/playback, GPIO and an RS422 serial input, making it the most feature-complete broadcast audio adapter in existence.

The GPIO consists of eight relay outputs and sixteen opto-isolated inputs. These enable the control of station equipment and sensing of news feeds and other events. Through the use of the WaveX extensions to its Windows multimedia drivers, the GPIO may be accessed using standard Windows mixer calls.

A unique feature of the ASI4336 is the RS422 serial input. This supports the direct input of a satellite receiver MPEG bitstream which can be recorded as a standard .WAV or .BWF file for later playback. The ASI4336 removes the MPEG transcode and analog-to-digital conversion process that typically occurs when recording network satellite feeds, improving the audio quality.

Three balanced stereo inputs and four MPEG-1 Layer II playback streams can be digitally mixed to four balanced stereo outputs. One stereo MPEG-1 Layer II record stream can be sourced from any of the three inputs. 20bit over-sampling A/D and D/A converters are used to provide greater than 90dB of Signal-to-Noise Ratio (SNR) and less than 0.005% of Total Harmonic Distortion+Noise (THD+N) when recording or playing.

The ASI4336 will be available in March 2000. Drivers for Windows 98, Windows NT and Linux are available on the company's website, www.audioscience.com.  For pricing contact AudioScience at 1-302-324-5333.
