Connecting the 1394 Interface x
Units fitted with an IEEE 1394 interface can output DSD data, which can be
decoded by a 1394–equipped dCS Elgar plus or Delius DAC.
do this: Check that your DAC is capable of DSD operation over an IEEE 1394 link. Set
the DAC to 1394 mode first.
do this: If you have set the output to DSD, connect ONE of the 1394 connectors on the
Purcell rear panel to the DAC using the IEEE 1394 cable supplied.
do this: Also connect Purcell‘s Wordclock OUT to Wordclock In on the DAC.
do this: Use the DAC’s Input button to select the 1394 input.
The 1394 interfaces will sync up, this may take 30 seconds. During this period,
Purcell may display Active and Inactive messages, finally setting down to
44.1→
→→
→DSD or similar.
The DAC may display Wait ..., followed by other messages before finally
settling down to Purcell.

IMPORTANT! Do not connect both of Purcell’s 1394 connectors to the DAC – this prevents
the IEEE 1394 interfaces synchronising.
