INSTALLING THE 828MK3 HARDWARE

OPERATING THE 828mk3 AS A CONVERTER
As explained earlier in “Using optical I/O to
operate the 828mk3 as a 16-channel expander” on
page 24, the 828mk3 can serve as a multi-channel
analog-to-digital converter when disconnected
from the computer and instead connected to
another device equipped with an ADAT optical
input. For example, you could connect the 828mk3
optical output to the optical input on another
MOTU audio interface, such as a Traveler, 896mk3
or even another 828mk3. The 828mk3 then serves
as a multi-channel expander that adds additional
mic, analog TRS and digital inputs to the interface.
The benefit of connecting the 828mk3 in this
manner (instead of as another FireWire interface)
is that you can seamlessly integrate the 828mk3’s
inputs into the on-board no-latency CueMix
monitor mixing in the interface, since the 828mk3’s
inputs are fed into CueMix via the interface’s
optical inputs.
If the device to which you are connecting the
828mk3 supports 2x optical sample rates (88.2 or
96 kHz), you can also use both banks of connectors
as discussed in “ADAT optical operation at 88.2 or
96 kHz” on page 24.
