The ASI5640, ASI5641 and ASI5644 are professional PCI Express sound cards designed for use in the installed sound, entertainment, and broadcast markets.
Providing 12 stereo play streams that are mixed to 4 balanced stereo outputs and 8 record streams fed from four balanced stereo inputs, the ASI564x family features AudioScience’s unique “anything to anywhere” routing and mixing.

The ASI5644 offers both balanced analog and AES/EBU inputs and outputs, while the ASI5640 has analog I/O only and the ASI5641 has AES/EBU I/O only. The maximum analog input and output level is +24dBu.

Uncompressed PCM, in a choice of precision is available for both recording and playback.

For emerging surround sound applications, SSX2? mode allows multichannel streams of up to 8 channels to be played and mixed.
