INPUT JACKS:
Use 1/4” TS or TRS (unbalanced or balanced) phone plugs to connect to these inputs from
your source. The MC6's INPUT jacks accept either balanced or unbalanced signals in LINE
mode and unbalanced signals in INST mode. Nominal input level is -10dBV in Line mode, and
-20dBV in INSTRUMENT mode. When a source is plugged into the input labeled “LEFT
(mono)”, the input signal is routed through both channels and thus appears at both output
jacks.This feature can come in handy as an active splitter to send the same signal to two guitar
amps, for example.
OUTPUT JACKS:
The OUTPUT jacks accept 1/4” balanced or unbalanced phone plugs in both LINE and INST.
modes, although the outputs are optimized for unbalanced operation when in INST. mode.
Nominal output signal level is the same as the nominal input level when the OUTPUT GAIN
control is set to the mid-position. Maximum output signal level is +21dBu, typical of profes-
sional gear running on a ±15 Volt power supply.
OPERATING LEVEL SWITCH:
This switch selects between “LINE” and “INSTRUMENT” operating levels.When the switch is in
the OUT position, a Line operating level is selected. It is optimized for -10dBV, although
“hotter” signals may be processed with a corresponding reduction in headroom (see specifi-
cations on page 11). When it is in the IN position, an “instrument level” operating level is
selected. It is optimized for low-level sources (-20dBV) requiring a high (500k
½
) input imped-
ance.This allows intruments, such as electric guitars,and high impedance unbalanced mics to
be plugged directly into the MC6 (typically into the “LEFT (mono)” input). Note that the oper-
ating level switch affects both input and output nominal levels simultaneously.
DC POWER CORD RECEPTACLE:
Plug the DC power adapter (supplied) into the MC6. Plug the other end into a standard wall
receptacle.Take care to route power cables away from audio lines. Note that the MC6 does not
have a power switch. Since power consumption is low, the MC6 may be left on for extended
periods of time. If you do not plan to use the MC6 for an extended period of time, unplug it.
BYPASS FOOTSWITCH JACK:
In addition to the front panel BYPASS SWITCH, the bypass function of the MC6 may be
accessed via the rear panel BYPASS FOOTSWITCH. When a standard latching footswitch
controller is attached to the BYPASS FOOTSWITCH JACK, the MC6 is toggled in and out of
bypass mode.The switch must be one whose 1/4” plug tip is shorted to sleeve when latched.
