  • Replacing the Digitorc M, the Digitorc 4 now has four AES 3 stereo channels on a Windows platform and is fully compatible with the Wave, DirectSound, DirectShow, MCI and Core Audio APIs. 

    At its heart is a Xilinx Spartan 6 FPGA, implementing both a single lane bus-master PCIe interface and four 24-bit AES3 codecs. Independent asynchronous sampling rate conversion on the inputs supports rates from 32kHz to 96kHz, while the output rate can be configured as 96kHz, 88.2kHz, 48kHz, 44.1kHz or 32kHz, either free-running or locked to an AES3 or AES11 reference on any of the inputs.

    Software sampling rate conversion is automatically inserted by Windows when the application rate does not match the hardware rate. Software bit depths of 32, 24, 16 and 8 bits are supported on playback and recording. The mixer functions allow inputs to be mixed back into each output, while a digital loopback is available from each playback channel into its corresponding record channel.

    High quality electrostatically-shielded transformers from Scientific Conversion are used on all the inputs and outputs.

    Multiple cards may be installed in a single PC.
