Digital Outputs
All of the outputs consistent with the selected output mode are active at the same time.
!
The Vivaldi Upsampler generates 24-bit PCM data but it does not have facilities to
reduce the word length to less than 24 bits. It will not give good results with older DACs
(or other equipment) that cannot process 24-bit data. ALL
dCS
converters will accept 24-
bit PCM data.
The
AES1
and
AES2
outputs (J) can be used individually at 32, 44.1, 48, 88.2, 96, 176.4 or 192kS/s
or DSD/64 in DoP format, or as a Dual AES pair at 88.2, 96, 176.4, 192, 352.8 or 384kS/s or DSD/64
in DoP format.
!
For Dual AES operation at 88.2, 96, 176.4 or 192kS/s or DSD, the
Settings > Dual AES
menu page must be set to
Dual AES On
, otherwise both outputs will carry single AES
data. If the output rate is 352.8 or 384, Dual AES mode is automatically selected.
2 SPDIF outputs are provided,
SPDIF1
on an RCA connector (K) and
SPDIF2
on a BNC connector
(L). These outputs carry SPDIF data for output rates at 32, 44.1, 48, 88.2, 96, 176.4 or 192kS/s or
DSD/64 in DoP format, even if
Dual AES
mode is
On
. They are disabled when the Output mode is
352.8kS/s or 384kS/s.
Digital Inputs
The standard PCM inputs are
AES
on a 3-way female XLR connector (M),
SPDIF1
&
SPDIF2
on RCA
connectors (N),
SPDIF3
on a BNC connector (O) and
SPDIF4
on a Toslink connector (T). The
electrical inputs will accept up to 24-bit data at 32, 44.1, 48, 88.2, 96, 176.4 or 192kS/s or DSD/64 in
DoP format. The Toslink input accepts data at up to 96kS/s and is not tested or guaranteed at higher
sample rates.
The
SDIF
interface will accept PCM data at sample rates up to 96kS/s. The interface consists of two
data inputs labelled
CH1
and
CH2
(P). Operation in SDIF mode requires that a word clock from the
source is connected to the
Word Clock In1
or
In2
connector (Q). Note that the interface can fail to
lock correctly if the data sample rate changes but the Word Clock does not.
