Connect Audio Inputs And Outputs - MOTU 828mkII User Manual

CONNECT AUDIO INPUTS AND OUTPUTS

The 828mkII audio interface has the following
audio input and output connectors:
8 balanced, +4 dB quarter-inch analog outputs
■
8 balanced +4 dB quarter-inch analog inputs
■
2 Neutrik™ XLR/quarter-inch analog inputs
■
2 quarter-inch analog sends for the front-panel
■
mic/guitar inputs
2 balanced, +4 dB quarter-inch TRS main outs
■
1 pair of RCA S/PDIF in and out
■
1 pair of optical in/out switchable between
■
ADAT ("Lightpipe") or optical S/PDIF (TOSLink)
Here are a few things you should keep in mind as
you are making these connections to other devices.
Quarter-inch analog
The quarter-inch analog inputs and outputs (1-8),
as well as the main outs, are balanced TRS
connectors that can also accept an unbalanced
plug. The outputs are all referenced to +4dBu. The
inputs can be manually set to either +4 or -10dBu.
Use the front panel controls to adjust the reference
level (+4/-10) as needed for each input (or input
pair) as follows:
1 Turn the PARAM knob until you see the "4/10"
setting displayed in the LCD, as shown below.
If turning the PARAM knob doesn't do anything,
press the SETUP knob once, and then turn it.

2 Turn the CURSOR knob until the desired input
flashes.
3 Turn (or press) the VALUE knob to toggle the
input between a +4 or -10dB reference level setting.
Front-panel mic/guitar/instrument inputs
Connect a microphone, guitar or other similar
instrument to the front-panel inputs. If your
microphone requires phantom power, move the
48V phantom power switch on the front panel to
the right (enabled). Use the trim knobs on the front
panel to adjust the input level as needed for each
input. Use the two input level meters on the front
panel (labeled MIC) to calibrate the level. These
meters register for both the XLR and TRS input.
☛
Do not connect a +4 (line level) XLR cable to
the front-panel inputs (because of the preamps).
Use a rear-panel quarter-inch input instead.
Mic/guitar/instrument sends
Each front-panel XLR/TRS input has a
corresponding send on the rear panel. The send
provides the pre amplified and calibrated input
signal, which you can then route to any other
device, such as compressor, guitar amp, outboard
EQ, reverb unit, etc. Use any 828mkII input
(analog or digital) as a return back into the
828mkII. From there, you will be able to route the
signal anywhere in the system, such as to the
computer and/or to any CueMix DSP mix bus.
Optical
Reminder: optical goes OUT to IN and IN to OUT,
like MIDI.
