4.5.5 D1 (with SYNC_IO board) + C1 (with SYNC_IO board) + T1 time reference
When both the D1 and the C1 are equipped with a SYNC_IO board, and an ultra-high stability clock generator such as the CH
Precision T1 10MHz time reference is available, optimum performances are obtained when both the D1 and C1 lock themselves
onto the external clock generator. Direct clock connections from the T1 to the devices is preferred over daisy-chaining. Audio
stream goes from the D1 to the C1, and clock is distributed to both D1 and C1 from the T1. If more DACs are available for extra
surround channels, they should also be connected directly to the clock generator. Schematic below shows how to connect such
system:
D1 – C1 – T1 connection when SYNC_IO equipped
The same applied if the D1 has multi-channel capability and more DACs are connected to the D1 for surround, center and sub
channels. In such cases:
•
D1 clock source: SYNCHRO BNC 75 Ohm
•
C1 clock source (for this input): SYNCHRO BNC 75 Ohm
