TRS quarter-inch analog inputs and outputs
Quarter-inch analog inputs and outputs are
balanced (TRS) connectors that can also accept an
unbalanced plug. The outputs are DC-coupled, so
they can be used for CV control output.
☛ Quarter-inch analog outputs are not
cross-coupled. Therefore, when connecting them
to an unbalanced input, use a TRS plug with the
ring disconnected. Not floating the negative
terminal will short it to the sleeve ground and
cause distortion.
Unbalanced RCA outputs
Connect the unbalanced RCA outputs to other
gear that has similar unbalanced RCA inputs, such
as DJ systems, karaoke equipment or consumer
audio devices.
Monitor outs
In a standard studio configuration, the monitor
outs are intended for a pair of primary studio
monitors, but they can be used as regular outputs
for any purpose.
MIDI CONNECTIONS
Connect your MIDI device’s MIDI IN jack to the
M series MIDI OUT jack (Connection A below).
Conversely, connect the MIDI device’s MIDI OUT
jack to the M Series MIDI IN jack (Connection B).

One-way MIDI connections
MIDI devices that do not receive MIDI data, such
as a dedicated keyboard controller, guitar
controller, or drum pad, only need Connection B
shown in Figure 3-4. Similarly, devices that never
send data, such as a sound module, only need
Connection A. Make both connections for any
device that needs to both send and receive MIDI
data.
Connecting additional gear with MIDI THRUs
If you need to connect several pieces of MIDI gear,
run a MIDI cable from the MIDI THRU of a
device already connected to the M Series interface
to the MIDI IN on the additional device as shown
below in Figure 3-5. The two devices then share
the M Series MIDI OUT port. This means that
they share the same set of 16 MIDI channels, too,
so try to do this with devices that listen to only one
MIDI channel (such as effects modules), which
makes it easier to avoid MIDI channel conflicts.
