The ASI6544 and ASI6540 are professional PCI 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 4 balanced stereo inputs, the ASI6544 and ASI6540 both feature AudioScience’s unique “anything to anywhere” mixing and routing.

The ASI6544 provides both balanced analog and AES/EBU inputs and outputs. The ASI6540 has analog I/O 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.

ASI6544 and ASI6540 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, SSX2™ mode allows multichannel streams of up to 8 channels to be played, recorded and mixed.
