Yamaha 111SC Owner's Manual
BATTERY REPLACEMENT
Be sure to replace the battery as soon as possible when the battery check
indicator lights in order to avoid reduced sound quality.
* Be sure to remove the battery if the instrument will not be used for an
extended period of time in order to prevent possible damage due to
battery leakage.
THE CONTROLS
The output jack is an EIAJ-standard 1/4" phone jack. Be sure to use an
appropriate connection cable.
The built-in preamplifier is automatically turned on when a plug is
inserted into the output jack. When not using the instrument, or when
playing it without amplification, be sure to remove the plug from the
output jack so that the preamplifier power is turned off.
Always set the VOLUME control to “0” when plugging in or unplugging
the connection cable.
The battery check indicator (BAT.) will light briefly when a plug is
inserted or removed from the output jack. This is normal and does not
indicate a malfunction.
Be sure to remove the battery if the instrument will not be used for an
extended period of time in order to prevent possible damage due to
battery leakage.

w BATT. (Battery Check) Lamp
When battery power is low the lamp will
light. Please replace the battery with a
new set as soon as possible. (Refer to
“BATTERY REPLACEMENT" section.)
e Equalizer Controls
When both the HIGH and LOW knobs
are set to "0", the signal will be flat (EQ
Pass).
HIGH : Rotate the knob to the right to
enhance the high frequencies
and create a brighter sound.
LOW : Rotate the knob to the right to
enhance the low frequencies
and add presence.
r Mic (Phase Adjustment)
* System 43 only
When the mic knob is set to its cen-
ter position, the mic is off.
Rotate the knob to the right (Normal)
to increase the mic mix level. At this
time, if feedback or howling occurs,
it is possible to reverse the phase
by rotating the knob to the left.
The same knob provides control of
both level and phase adjustment.
Caution
Rotating the HIGH and LOW knobs
to the right increases the overall
output level. Likewise, rotating the
MIC. knob right or left also in-
creases the overall output level. If
the overall output level is increased
in this manner, use the VOL. knob
to adjust the volume level.

Mic Head
CONDENSER MIC ADJUSTMENT
(System 43 only)
The condenser mic is attached inside the body (behind the preamplifier) with a
flexible pipe that allows free adjustment of the mic's direction.
A variety of tone variations are achievable by changing the direction of the mic
head.
• When the guitar was shipped from the factory, the mic head is positioned
inside the body slightly pointed towards the sound hole and about 10mm
from the guitar's top. (You can see it from the sound hole.) This setting is
good for picking up the sound of the strings being plucked. (See diagram 1)
• When the mic head is slightly pointing toward the inside of the body this
setting will pickup a bigger body sound. (See diagram 2)
* Try some different mic placements and select the one you prefer.
