ASI6622 - PCI Express Sound Card   

The ASI6622 is a professional PCI-Express sound card designed for use in radio broadcast automation.

Providing 6 play streams that are mixed to 2 balanced stereo outputs and 4 record stream fed from 2 balanced stereo input, the ASI6622 features AudioScience’s unique “anything to anywhere” mixing and routing.

The ASI6622 provides a balanced analog inputs and outputs. The maximum analog input and output level is +24dBu.

A choice of uncompressed PCM, MPEG layer 2 and MP3 is available for both recording and playback. All compression is handled by an on-board floating point DSP, allowing the host computer to focus on other tasks.

ASI6622 functionality includes MRX multi-rate mixing technology which allows streams of different sample-rates and formats to be mixed digitally. TSX time scaling allows compression/expansion of any or all playback streams in real time with no change in pitch.
