When using the Network Bridge with one of the dCS legacy DACs you need to keep in mind that the older DACs (Scarlatti / Paganini / Debussy) only output a 44.1KHz clock signal via their word clock output. This is fine for file playback where the source material is a multiple of 44.1K (44.1KHz, 88.2KHz, 176.4KHz, 352.8KHz, and DSD), but the DAC will not be able to lock to the Bridge when files using a 48KHz clock multiple are used.
Fortunately the Bridge has a Word clock output as part of the SDIF interface. Adjacent to the AES and S/PDIF connections on the bridge you’ll see three BNC connections labeled CH1, CH2, and OUT. Connect a clock cable from the connector on the Bridge labeled OUT to the WClock In connector on your DAC. Then set your DAC to sync to an external word clock.
The oscillators used in the Network Bridge are of similar quality to that used in your DAC and this configuration has proven to yield excellent results.
