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