PC-AD2 2 Stereo Analogue I/O & 2 Stereo AES-3 I/O PCIe Half Height Sound Card








The PC-AD2 is a dual stereo analogue input/output and dual stereo AES-3 digital input/output sound card in the PCIe half height format. One of the analogue inputs can be used as a mic input, there is a dedicated AES-11 sync input and also 2 GPIOs. It is fully compatible with the Windows™ Wave, DirectSound, DirectShow, MCI and Core Audio APIs, supporting audio up to 24 bit, 192kHz.



  • 2 independent transformer-coupled AES-3 inputs and outputs.
  • 2 independent high level balanced stereo inputs and outputs.
  • One of the stereo line inputs can act as a dual mono or stereo mic input with +48V phantom power and limiter.
  • 1 AES-11 synchronisation input.
  • 2 opto isolated GPIOs.
  • 24-bit audio resolution.
  • Sampling rates up to 192kHz.
  • Asynchronous sampling rate converters on each input.
  • Card synchronisation to any input, AES-11 input or other PC-AD2 card.
  • 32 and 64 bit drivers for Windows7/8/10, Windows Server 2008/R2, 2012/R2.
  • WDM-compliant supporting Wave, DirectSound, DirectShow and Core Audio APIs.
  • Simultaneous record/play per channel.
