Digital audio connections
The input from digital audio devices may be con-
nected using the optical “lightpipe” input connection
(
ADAT/OPT ).
By default, this is set to be 8-channel data (ADAT
format). However, you can use the software Control
Panel to change the source of the SPDIF between the
optical and coaxial sources.
Despite the on-screen label, AES/EBU data can be
input here.
The FW-1884 can also output multitrack digital data
from the
ADAT/OPT output, either providing another
eight outputs independent of the analog outputs, or
duplicating them (these use ADAT format), or it can
output a stereo pair in TOS format which duplicates
the coaxial setting (see below).
If the optical input is not being used for SPDIF input,
the coaxial input can be used for this purpose.
The coaxial digital audio output can be used as an
independent stereo output, or can duplicate the first
two analog outputs.
After make these connections, set the word clock
appropriately as described below.
Status indicators
The four green status indicators show the current sta-
tus of:
• FireWire The IEEE 1394 connection
• CLOCK The system clock
• ADAT The 8-channel optical input
• D IN The stereo digital input (AES/EBU or S/
PDIF) from either the coaxial input, or from the
optical input if this has been selected from the Con-
trol Panel as the S/PDIF source
When these indicators are lit, it means that the appro-
priate connection has been made and the signal is
being received properly.
A flashing FireWire indicator shows that there is an
error in the IEEE 1394 connection. No indicator
means “no connection” for all indicators except
CLOCK . If any of the other three indicators are flash-
ing fast, this shows an input error. A slowly flashing
indicator indicates a lock problem.
