Audio Science ASI6520 / ASI6522 PCI Sound Card

Overview

The ASI6522 and ASI6520 are professional PCI sound cards designed for use in radio broadcast automation.

Providing 4 or 6 play streams that are mixed to 2 balanced stereo outputs and 2 or 4 record streams fed from 2 balanced stereo inputs, the ASI6522 and ASI6520 feature AudioScience’s unique “anything to anywhere” mixing and routing.

The ASI6522 provides both balanced analog and AES/EBU inputs and outputs. The ASI6520 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.

ASI6522 and ASI6520 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.
