Digital Audio Input Section
OUT / IN:
OUT position selects conversion from analog to digital.
IN position selects conversion from digital to digital.
OPTIC / BNC:
If the DATA DIR switch is set to IN, this selects data
input between optical or BNC connectors (data format is
selected in Interface Format Section).
Interface Format Section
RAW / SDIF-3:
When DSD is on BNC the user has the choice between
RAW and SDIF-3 formats.
DSD / PCM:
This switch selects DSD or PCM format on the BNC
connectors (in both directions).
OPTIC1 / OPTIC2: Selects format 1or 2 for both input and output (currently
not implemented - only 1 format).
16 / 24 BITS:
The wordlength of the PCM outputs can be selected
between 16 and 24 bits. The 16 bit position uses noise
shaping to convert original format of 24 bits to 16 bits.
Error Indicator is lit for illegal switch positions (audio outputs are muted)
Analog Input Level
LO / HI:
The LO position allows the user to set levels between
+20dbu and +32dbu.
The HI position allows the user to set the levels between
+8dbu and +20dbu.
Clipping indicators
The clipping LED’s come on when the level on the PCM outputs reach
0dbFS. This level corresponds to 0dbSACD on all DSD outputs. However,
the levels on the DSD outputs are allowed to go up to +3dbSACD.
