(balanced)
Balanced input is a method of transmitting a signal using three conductors, which are named
"hot", "cold", and "ground". The plug is divided into three sections. Plugs used for stereo signals
are divided into three sections in the same way, but are wired differently. Do not mix these two
type of connections. Stereo signals cannot be input to mic input jack 1 or jack 2 (INPUT 1, 2).
Unbalanced input is the usual method of transmitting a signal using two conductors, a signal line
and a ground. The plug is divided into two sections.
Types of mic
Mics can be broadly classified as either dynamic mics or condenser mics.
The M-100FX can accept either type, and can also accept "plug-in powered
mics"—the miniature condenser mics designed for connection to the mic
jack of a computer or the recording jack of an MD (mini disc) recorder.
The plug-in powered mic jack accepts either monaural or stereo mics. If a
stereo plug is connected to mic input jack 1 (INPUT 1), channel 1 will
process the left/right signals in stereo. If a plug-in powered mic is
connected, and you connect a mic to the XLR jack, no audio will be input
from the mic connected to the XLR jack. Only the signal from the plug-in
powered mic will be sent to the mixer.
If you are using the plug-in powered mic jack, the input level knob (GAIN)
will not adjust the input level.

Basic operation
Only a plug-in powered
mic can be connected to the
plug-in powered mic jack.
If a different type of mic,
such a mic with a
conventional stereo mini
output plug is connected to
this jack, the circuit may be
damaged.
