ASI 6644

The ASI6644 is a professional PCI-Express sound card designed for use in radio broadcast automation. Providing 12 play streams that are mixed to 4 balanced stereo outputs and 8 record streams fed from four balanced stereo inputs, the ASI6644 features AudioScience’s unique "anything to anyware" mixing and routing.

The ASI6644 provides both balanced analog and AES/EBU 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.

ASI6644 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.

For emerging surround sound applications, SSX mode allows multichannel streams of up to 8 channels to be played, recorded and mixed
