Introduction to the M3

5. S/P DIF IN & OUT
These jacks provide 24-bit optical S/P DIF input and
output, for connecting to computer audio systems,
digital mixers, MDs, etc.
Optical S/P DIF is sometimes called TOSLINK, and
formally named (hold your breath!) IEC60958, EIAJ
CP-1201. Make sure to use optical cables designed for
digital audio.
Whenever you use digital audio connections, make
sure that all connected systems are set so that there is
one and only one word clock master. You can set the
word clock for the M3 using the Global page System
Clock
parameter. For details, please see “System
Clock” on page 359 of the Parameter Guide.
OUT(MAIN) jack
This optical S/P DIF output carries a digital version of
the main L/R outputs.
Note: That the VOLUME MAIN slider does not adjust
the S/P DIF output level.
IN jack
You can use this optical S/P DIF input for recording,
sampling, and real-time mixing through the built-in
effects.
It can be used simultaneously with the two analog
inputs, if you like.
6. AUDIO INPUTS
You can use the audio inputs for sampling, and real-
time mixing through the built-in effects.
AUDIO INPUT 1, 2
These are unbalanced 1/4" phone jacks.
LEVEL knobs
This adjusts the input level of the AUDIO INPUT 1, 2
jacks. After setting the MIC/LEVEL switch
appropriately, use this knob to adjust the gain.
MIC/LINE switches
These set the input’s nominal signal level. Set these
switches according to the type of device that you’re
connecting, and then use the LEVEL knobs (described
below) to optimize the gain.
Use the LINE setting when connecting to mixers,
computer audio systems, signal processors, or other
synthesizers.
Use the MIC setting only when connecting a
microphone.
7. AUDIO OUTPUTS
All of the analog audio outputs use unbalanced 1/4"
phone jacks, referenced to a +4dBu signal level.
Connect these outputs to the input jacks of your amp
or mixer. In addition to the L/MONO and R main
stereo audio outputs, the M3 provides eight individual
audio outputs.
The sound from each oscillator, drum, timbre/track, or
insert effect can be freely routed to any output.
Additionally, you can route the metronome sound to
an individual output, to separate it from the stereo
mix. For details, please see “Routing effect settings” on
page 155.
(MAIN) L/MONO, R
These are the main stereo outputs; their volume is
controlled by the VOLUME MAIN slider. All of the
factory Programs and Combinations are programmed
to play through these outputs.
When editing sounds, or when setting up a Song in
Sequencer mode, you can access the main outputs by
setting Bus Select to L/R.
If no cable is connected to the R output, L/MONO will
carry a mono summation of the stereo signal. So, if you
are connecting to a device which does not have stereo
inputs (such as a simple keyboard amp), use the L/
MONO output.
(INDIVIDUAL) 1, 2, 3, 4
These 4 additional audio outputs let you isolate
sounds, or audio inputs for recording or complex live
sound setups.
These can be used as stereo or mono outputs, in any
combination. You can also use the Global P0: Basic
Setup– Audio page L/R Bus Indiv. Out Assign
parameter to map the main stereo outputs to any of
these output pairs, if you like.
Note that the individual outputs are not affected by the
VOLUME MAIN slider.
8. Headphone jack
This stereo 1/4" headphone jack carries the same signal
as the Main L/R outputs.
The headphone volume is controlled by the VOLUME
MAIN slider.
9. EXB-FW option
If you install the optional EXB-FW in the M3, you’ll be
able to enjoy the following total recall control
functionality from a host application in which the
included M3 Plug-in Editor is running.
• Send and receive MIDI data to and from the DAW
software
• Edit and set up the parameters of the M3’s various
modes
• Send and receive the M3’s 2-in and 6-out channels
of digital audio.
If the EXB-FW is installed in the M3, it will have the
following specifications.
• Audio input/output: 24-bit, 48 kHz fixed, 2-in/6-
out
• MIDI input/output: one port in/out (sixteen MIDI
channels in/out)
Please note the following points.
• The two jacks have the same function. The
connector to which your computer is not connected
can be used as a daisy-chain connector for a
FireWire device that can be recognized by your
computer. (The M3 will not recognize this device.)
• The EXB-FW does not supply bus power.
For details on installing the EXB-FW into the M3,
please see page 202.
