4.1.11 GROUP/MATRIX OUT
By default, these eight male XLR connectors provide
balanced, line-level outputs for Groups 1–8. However,
when the
MATRIX
mixer is active, each output can
provide a separate mix of virtually any input source. See
Matrix Mix
on page 44 for details.

4.2 Digital I/O
This section discusses the rear panel digital I/O
(Figure 4-4).
4.2.1 ADAT DIGITAL I/O
Six built-in Toslink connectors (INPUTS A–C, OUT-
PUTS A–C) provide 24 channels of 24-bit digital, ADAT
optical lightpipe I/O at 44.1/48 kHz sample rates. At
88.2/96 kHz, the signal is multiplexed (SMUX format),
which reduces the number of I/O channels to 12.
The optional ADAT I/O Expansion Card provides ad-
ditional Toslink connectors (Expansion INPUTS A–C,
Expansion OUTPUTS A–C) for channels 13–24 when
operating at 88.2/96 kHz. The following table summariz-
es the channels allocated under each sample rate, with
and without the expansion card.
