ABOUT THE 828MK3
11
The quarter-inch outputs are referenced to a +4
dBu line level output signal. The inputs have
+22 dB of input gain and -96 dB of cut, allowing
them to accommodate both -10 dBu and +4 dBu
level signals.
Precision Digital Trim™
All of the 828mk3’s analog inputs are equipped
with digitally controlled analog trims, adjustable in
1 dB increments. The mic/guitar input trims can be
adjusted using front-panel digital rotary encoders
that provide feedback in the front panel LCD with
up to 53 dB of boost. All analog inputs, including
eight rear-panel TRS analog inputs, can be
trimmed using the front panel LCD or using the
828mk3’s included CueMix FX control software for
Mac and Windows. This gives you finely-tuned
control of trim settings for synths, effects modules,
and a wide variety of analog inputs for optimum
levels. Different trim configurations can then be
saved as preset configurations for instant recall.
Mic/guitar sends
Before A/D conversion, the pre-amplified signal
from each front-panel mic/guitar input is routed to
one of the two rear-panel quarter-inch analog
sends, so that you can insert a favorite outboard
EQ, compressor, amp or effects processor to the
mic/guitar input signal before it is converted to
digital form. The resulting output from the
outboard gear can be fed back into the 828mk3 via
one of the eight TRS analog inputs on the rear
panel, for routing to the computer and/or inclusion
in the 828mk3’s built-in monitor mixes.
Main Outs
The main outs are equipped with 24-bit 192 kHz
D/A converters and serve as independent outputs
for the computer or for the 828mk3’s on-board
CueMix FX mixes.
Optical
The two optical banks provide 16 channels of
ADAT optical at 44.1 or 48 kHz, 8 channels of S/
MUX optical I/O at 96 kHz or two banks of stereo
TOSLink at rates up to 96 kHz. The banks operate
independently, including input and output,
allowing you to mix and match any optical formats.
For example, you could receive 4 channels of
96 kHz S/MUX input on Bank A while at the same
time sending 96 kHz stereo optical S/PDIF
(“TOSLink”) from the Bank A output.
S/PDIF
The 828mk3 rear panel provides S/PDIF input and
output in two different formats: RCA “coax” and
optical “TOSLink”. The RCA jacks are dedicated to
the S/PDIF format. The TOSLink jacks can be used
either for either TOSLink or ADAT optical, as
discussed earlier.
MIDI I/O
The 828mk3’s standard MIDI IN and MIDI OUT
jacks supply 16 channels of MIDI I/O to and from
the computer via the 828mk3’s FireWire
connection.
On-board SMPTE synchronization
The 828mk3 can resolve directly to SMPTE time
code via the quarter-inch SMPTE input, without a
separate synchronizer. A SMPTE out jack is also
provided for time code generation. The 828mk3
provides a DSP-driven phase-lock engine with
sophisticated filtering that provides fast lockup
times and sub-frame accuracy.
The included MOTU SMPTE Console™ software
includes a complete set of tools for generating and
regenerating SMPTE time code, providing a way to
slave other devices to the computer. Like
CueMix FX, the synchronization features are
cross-platform and compatible with all audio
sequencer software that supports the ASIO2
sample-accurate sync protocol.
