3.3.2.1
Standard digital outputs
Each DIGITAL_OUT board provides three standard digital outputs: AES-EBU (carrying consumer encoding), Coaxial (S/PDIF) and
Optical (TOSLINK). Digital output is fixed at 16bits/44.1kHz on all standard outputs. If an SACD is played in the D1, the DSD
stream is down converted to 16bits/44.1kHz on the standard digital outputs. When a CD is played, the data from the disc is
directly transferred to the standard digital outputs.
3.3.2.2
CH Link digital audio interface
Each DIGITAL_OUT board includes a CH Link proprietary digital audio interface. This interface carries both complete audio stream
and control information. Use this link as the preferred interface when connecting your D1 to other CH units such as C1 converters.
The proprietary CH Link digital audio interface allows for high definition uncompressed digital audio transfer and supports both
DSD and PCM (up to 705.6 / 768 kHz). For digital content protection reasons, the CH Link interface cyphers the native DSD stream
from SACD when transferring such data.
3.3.3 Stereo ANALOG_OUT boards
ANALOG_OUT boards provide analog audio output capabilities. ANALOG_OUT boards for L/R, Ls/Rs and C/Sub channel pairs can
be installed into D1 for analog stereo or multi-channel support. DIGITAL_OUT, stereo ANALOG_OUT and monaural ANALOG_OUT
boards can be combined, providing for instance digital output on the main (L/R) channels and analog out on Ls/Rs and C/Sub
channels. Stereo ANALOG_OUT boards provide both balanced (XLR) and single-ended (RCA) analog audio outputs. Following
drawing shows the layout of the Stereo ANALOG_OUT board connectors and naming for the different channel pairs:

3.3.4 Monaural main ANALOG_OUT boards
ANALOG_OUT boards provide analog audio output capabilities. Monaural ANALOG_OUT board pairs for Left and Right channels
can be installed into D1 for analog support on main channels. DIGITAL_OUT, stereo ANALOG_OUT and monaural ANALOG_OUT
boards can be combined, providing for instance monaural analog output on Left and on Right channels, and stereo analog output
on Ls/Rs and C/Sub channels. Monaural ANALOG_OUT boards provide true fully-balanced (XLR), single-ended 75 Ohm (RCA) and
single-ended 50 Ohm (BNC) analog audio outputs. Following drawing shows the layout of the Monaural ANALOG_OUT board
connectors and naming:
