Setting Up

Connecting Headphones or External Audio Equipment (PHONES/OUTPUT Jack)

Headphones
Any pair of stereo headphones with a standard stereo
phone plug can be plugged in here for convenient
monitoring. The speakers are automatically shut off
when a plug is inserted into this jack. This setting can
be changed so that speaker sound is always on regard-
less whether a plug is inserted or not (page 58).
External Audio Equipment

The PHONES/OUTPUT jack also functions as an
external output. You can connect the PHONES/OUT-
PUT jack to a keyboard amplifier, stereo system,
mixer, tape recorder, or other line-level audio device
to send the instrument's output signal to that device.
Optimum setting
Output gain level for this jack is set to a value suitable
for connecting headphones, as the default setting. You
can switch this to the value suitable for connecting an
external audio device. For details on how to switch the
value, see page 58.

CAUTION
• Before connecting the instrument to other electronic com-
ponents, turn off the power of all the components. Also,
before turning any components on or off, make sure to set
all volume levels to minimum (0). Otherwise, damage to
the components, electrical shock, or even permanent
hearing loss may occur.
CAUTION
• Do not use the instrument/device or headphones for a long
period of time at a high or uncomfortable volume level, since
this can cause permanent hearing loss. If you experience any
hearing loss or ringing in the ears, consult a physician.
NOTICE
• When the instrument's sound is output to an external
device, first turn on the power to the instrument, then to
the external device. Reverse this order when you turn the
power off. If the instrument's power is automatically turned
off via the Auto Power Off function (page 19), first turn off
the external device, then turn on the power to the instru-
ment then the external device again.
NOTICE
• Do not route the output from the PHONES/OUTPUT jack to
the AUX IN jack. If you make this connection, the signal
input at the AUX IN jack is output from the PHONES/OUT-
PUT jack. These connections could result in a feedback
loop that will make normal performance impossible, and
may even damage both pieces of equipment.
NOTE
• Use audio cables and adaptor cables having no (zero) resis-
tance.
