Yamaha APX9NA 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 (BATT.) 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.

Condenser Mic
CONDENSER MIC ADJUSTMENT
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.
Sound Hole Cover
(Accessory)
Feedback often occurs when controls are boosted on the electric acoustic guitar to
match the volume of other instruments when playing in a band.
Another source of feedback results from using the MIC. VOL. control to increase the
output from the internal condenser mic.
When the instrument is used under the conditions described above, the Sound Hole
Cover should be inserted into the sound hole.
With the Sound Hole Cover in place, feedback is effectively reduced.

LOW : Boosts or cuts the level of the low frequencies.
MID
: Boosts or cuts the level of the middle frequencies.
The AMF control
r adjusts the center frequency of the band affected by
this control.
HIGH : Boosts or cuts the level of the high frequencies.
r AMF Control
Sets the center frequency of the band of frequencies affected by the MID equalizer
control. The range is from 80 Hz to 5 kHz.
* This control has no effect when the MID equalizer control is set to its center (“0”)
position.
t MIC. VOL.
Controls the volume of the condenser mic that is located inside the body (to the back
of the preamplifier).
* Setting the volume level too high may result in feedback causing damage to your
sound system. If feedback occurs, turn down the MIC. VOL. control until the feedback
stops or use a sound hole cover to prevent feedback.
y
PHASE switch for the MIC
Using this switch will change the tone when the mic signal is added to the guitar’s
tone. It can be effectively used to control feedback depending upon the devices that
are used and knob settings. Use it as you like.
q VOL. (Volume) Control
Adjusts the overall output volume level.
* Make sure that the VOL. is turned to “0”
before connecting or disconnecting.
w BATT. (Battery Check) Indicator
This indicator will light when the battery needs
to be replaced.
Please replace the battery as soon as
possible when the BATT. indicator lights.
