AudioScience ASI6740 PCI Express w/ GPIO PCI Express 4 record, 4 play/4 out, Analog, MPEG Layer2/3/PCM

The ASI6740 and ASI6744 are professional low profile PCI-Express sound cards 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 ASI6740 and ASI6744 feature AudioScience’s unique “anything to anywhere” mixing and routing.

The ASI6744 provides both balanced analog and AES/EBU inputs and outputs. The ASI6740 provides balanced analog inputs and outputs only. 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.

ASI6740 and ASI6744 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 surround sound applications, SSX2 mode allows multichannel streams of up to 8 channels to be played, recorded and mixed.
