ASI5020 - PCI Sound Cards


The ASI5020 is a professional PCI sound card designed for use in radio broadcast automation.

Providing 6 play streams that are mixed to 2 balanced stereo outputs and 4 record streams fed from 2 balanced stereo inputs, the ASI5020 features AudioScience’s unique “anything to anywhere” mixing and routing.

The ASI5020 provides balanced analog inputs and outputs. The maximum analog input and output level is +24dBu.

A choice of 8, 16, 24, or 32 bit PCM is available for both recording and playback. All mixing and metering is handled by the on-board fixed point DSP, allowing the host computer to focus on other tasks.
