The Prism Sound 8C-DSD is an 8-channel I/O module for Direct Stream Digital input and output for the ADA-8XR mainframe

The 8C-DSD I/O Module provides eight channels of analog-to-DSD and, conversely, DSD-to-analog conversion when combined with the ADA-8XR’s analog line input and line output modules. The 8C-DSD module also allows for PCM-(Pulse Code Modulation)-to-DSD and DSD-to-PCM conversion in configurations where a PCM-type I/O module, such as an 8C-AES module is also installed in an ADA-8XR mainframe. In such a case, PCM synchronous sample rate conversion can also be performed between the PCM input and output for all eight channels.

8C-DSD I/O Module—Just the Facts:

  • Eight channels of analog-to-DSD and DSD-to-analog conversion
  • Also allows for PCM/DSD and DSD/PCM conversion
  • Oversampled 1-bit audio
  • Transmits in SDIF 2 and 3 via coaxial breakout cables or Cat5e
  • Connects DSD audio sources direct to workstation via Pro Tools 8C-PTHD I/O module

Prism Sound 8C-DSD I/O Module—Under the Hood

The DSD interface format carries an over-sampled one-bit representation of the audio signal as delivered on Super Audio CDs (SACDs). It can transmit the DSD data in either SDIF 2 (sometimes known as DSD RAW) or SDIF 3 formats, using coaxial cables via multi-connector breakout cable, or optionally in the MAC DSD / SuperMAC format using a CAT5E cable. While the DSD format uses a fixed sample rate of 2.8224MHz, the ADA-8XR’s DSD I/O Module enables you to run DSD-connected Paths with any of the ADA-8XR's sample rate and sync options.


When used in conjunction with a dedicated workstation I/O Module, such as Prism Sound’s 8C-PTHD Pro Tools HD I/O Module, the 8C-DSD I/O Module allows DSD audio sources and destinations to be connected to the workstation directly.

For master archiving or releasing high-resolution DSD audio in commercial formats, add an 8C-DSD I/O module to your Prism Sound ADA-8XR mainframe. For more information or assistance configuring a system, call or chat online with your PAD Studio Integrator today.

 

Unless otherwise stated, all performance specifications are quoted RMS, A-weighted, band-limited 20Hz-20kHz, with PCM sampling at 96kHz and word length 24 bits, and with DSD line-up normal. Note that quotation of performance using A-weighting filters is not generally the policy of Prism Sound; however, the noise-shaped nature of DSD signals means that A-weighted measurements are more representative of subjective performance than are un-weighted measurements.

(PCM to) DSD to Analog Performance

The following DSD to Analog specifications are measured using an ADA-8 Path in PCM to DSD mode as the signal source (since no standard DSD test source is available). They are as the Analog Line Output Module, except for the following:

  • Maximum input level: 0dB SACD (Normal) / +3.1dB SACD (Hot)
  • Absolute gain accuracy: ±0.1dB
  • THD+N (997Hz, -1dBFS): <-100dB (0.001%)
  • Dynamic range (997Hz, -60dBFS): >106dB
  • Frequency response -0.05dB: 10Hz-35kHz; -3dB: 3.9Hz-40kHz
