The IEEE
interface (Y) outputs encrypted DSD data. 1394 interfaces are great for carrying lots of
1394
digital data - but are very poor at transmitting a stable clock, so a separate Word Clock connection is
required. The two 1394 ports are identical – they can be used as data outputs or as a pass-through.
Note that the 1394 bus must not be connected in a loop as this will prevent the system initialising.
Word Clock Input / Output
The
connector (T) will accept standard word clock from the source equipment or a master
W/Clock In
clock at 32, 44.1, 48, 88.2 or 96kHz. Unlike the DAC, the clock frequency does not need to be an
exact multiple of the input data rate provided the two rates are synchronous. Set the
Settings / Sync Source
source (e.g. the CD Transport) MUST be locked to the same clock, otherwise the SYSTEM will not be
locked and periodic clicks will be heard on the outputs.
The
connector (U) carries word clock at the same frequency as the single-wire output
W/Clock Out
sample rate, or 44.1kHz for DSD. For example, if the output is set to 192kS/s Dual AES, the
connector carries a clock at half this rate – 96kHz.
Out
Word clock is used for synchronisation only, it does not carry digital data.
SUC
Connector
The
connector (Z) is an RS232 interface, primarily used to remotely control the unit during
SUC
automated testing. Please contact dCS for advice on using this interface with a household automation
system. Note that we recommend using infra-red remote control instead.
Mains inlet
Power is connected via a standard IEC320 connector (P), protected by a fuse (Q) and isolated by a 2-
pole power switch (O).
