swissonic aD 96, User Manual

Page: 16 / 22

S/MUX. AD96 settings: Sample rate: 88 or 96,
B/MUX: off, S/MUX on, Output resolution: 20
bits. In 96 kHz mode, there’s plenty of non-audible
spectrum (between 20 and 40 kHz) to place the
dither, so the difference between this mode and
real 24 bits is non-decelable. AD96, together with
the matching DA96 and 20-bit MDMs can be used
to build a budget-conscious mutitrack recording
system with unmatched performance.
The unit provides two AES/EBU outputs, which trans-
mit the audio data from all channels at all times. The
frequency of operation of the AES/EBU outs always
equals the internal operation frequency of the AD96.
As shipped by the factory, the unit will output data in
the «professional» format, with 110
Ω
balanced, 5 Vp-p
signal level.
Jumpers inside the unit allow the «consumer» format
and/or output levels to be selected. To select con-
sumer format for both outputs, remove jumper JP13.
To select consumer levels and impedance (75 ohm,
0,5 Vp-p) place jumpers JP10 and 11 in the 2–3 posi-
tion. An adapter that transforms the balanced
AES/EBU out to the unbalanced S/PDIF coax inter-
face is shown in figure 14.
