Let’s get back to this screen:
The
„Dual Wire Mode switch“
allows to set the XLR and
RCA digital outputs to the dual wire mode. In this mode the XLR
output becomes the left audio channel and the RCA output be-
comes the right channel. This mode is useful e.g. for older D/A
Converters which support higher sampling rates in dual wire
mode only. The dual wire mode (when selected) is active only for
sampling rates of 176.4 kHz or 192 kHz. For all other sampling
rates the MAN301 stays at single wire mode. The settings for the
RCA output (i.e. the volume trim and the mute on/o
ff
) are not
relevant in dual wire mode. The settings for the XLR output (vol-
ume trim, mute) are relevant for both XLR and RCA outputs.
The
„Dual Wire Word Clock Half Rate Switch“
pad se-
lects the sampling frequency at the BNC word-clock output con-
nector if the Dual Wire Mode is enabled. If the switch is set to
O
ff
, the sampling frequency at the BNC always reflects the cur-
rently active sampling frequency. If the switch is set to On, then
in dual wire mode 176.4kHz, the sampling frequency at the BNC
is 88.2kHz. And for dual wire mode 192kHz, it will be 96kHz.
The
„Sync source switch“
selects the source for the sam-
pling frequency. The „Internal“ setting as to be selected if no ex-
ternal sync source is connected.
The
„Digital Input switch“
selects the input to the audio
device. This feature is currently not used. (The input source
when the Pre-amp mode is selected is set elsewhere.)
The
„RCA“ or „XLR“
entries reveal a window like this:
