Analogue Outputs
The unit features independent
Balanced Outputs
(L) on XLR connectors and
Unbalanced Outputs
(M) on RCA connectors. The Left channel outputs are in the top row and the Right channel outputs are
on the lower row.
Our
Balanced Outputs
are intended to be connected to
true balanced inputs only. They are electronically
balanced and floating, so they behave like an audio
transformer. This arrangement enhances the rejection
of hum and interference picked up by the cable when
used with a true balanced input.
Most other DACs use a much simpler circuit that does
not offer the same level of performance.
!
Some amplifier manufacturers provide unbalanced inputs on XLR connectors by leaving
pin 3 floating. This arrangement does not work correctly with a floating output stage,
resulting in extra noise, unstable signal levels and a “thin” sound. If you want to use the
Vivaldi One with this type of input, link pin 3 to pin 1 in the cable at the amplifier end. In
such cases, we recommend that you use the
Unbalanced Outputs
instead.
AES Digital Inputs
The
AES1
and
AES2
(N) inputs can be used individually at sample rates up to 192kS/s, including
DoP/64.
If the
Dual AES
menu page is set to
On
or
Auto
,
AES1+2
can be used together as a
Dual AES
pair at
88.2, 96, 176.4, 192, 352.8 or 384kS/s. The pair will also accept
dCS
-encrypted SACD data from Vivaldi
/ Scarlatti / Paganini Transports and DoP data (DSD/64 or DSD/128 over PCM).
For Dual AES mode to work correctly, the source must actually generate Dual AES data,
not just the same single AES data on 2 connectors!
