ASI5520 PCI and ASI5620,5622 PCI Express Linear Sound Cards


The ASI5520, ASI5620 and ASI5622 are professional PCI sound cards designed for use in radio broadcast automation. The ASI5520 is a PCI adapter, the ASI5620 and ASI5622 are PCI Express (PCIe) adapters.

The adapters offer 6 play streams that are mixed to 2 balanced stereo outputs and 4 record streams fed from 2 balanced stereo inputs, and feature AudioScience’s unique “anything to anywhere” mixing and routing.

All three cards provide balanced analog inputs and outputs. The maximum analog input and output level is +24dBu. The ASI5622 adds 2 AES/EBU inputs and outputs.

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.

  • 2 AES/EBU inputs and outputs (ASI5622 only)
  • 4 stereo streams of record from 2 stereo inputs
  • PCI interface (ASI5520) or PCIe interface (ASI5620, ASI5622)
