If your system does not include an Upsampler, set the Transport to Vivaldi Mode and connect the Dual AES out to the DAC.
The Scarlatti & Paganini DACs have only one Dual AES input, so you will need to decide which source is most important to you when setting up a full system.
– If your priority is SACD, use Dual AES from the Transport with Vivaldi Mode tuned on. For CD playback, use 1394 from the Upsampler.
– If your priority is CD, use Dual AES from the Upsampler. For SACD playback, use 1394 from the Transport.
In both cases, make sure the system is correctly clocked.
