A standard pair of stereo headphones
can be plugged in here for private prac-
tice or late-night playing. The internal
stereo speaker system is automatically
shut off when a pair of headphones is
plugged into the PHONES jack.
An optional Yamaha FC4 or FC5
footswitch can be plugged into the rear-
panel SUSTAIN jack for sustain control.
The footswitch functions like the damper
pedal on a piano — press for sustain,
release for normal sound.
The AUX OUT R and L+R/L jacks
deliver the output of the PSR-620 for
connection to an external amplifier, mix-
ing console, PA system, or recording
equipment. If you will be connecting the
PSR-620 to a monophonic sound sys-
tem, use only the L+R/L jack. When a
plug is inserted into the L+R/L jack
only, the left- and right-channel signals
are combined and delivered via the
L+R/L jack so you don’t lose any of the
instrument’s sound.

The MIDI IN connector receives
MIDI data from an external MIDI device
(such as a MIDI sequencer) which can
be used to control the PSR-620. The
MIDI OUT connector transmits MIDI
data generated by the PSR-620 (e.g. note
and velocity data produced by playing
the keyboard). More details on MIDI are
provided on page 81.
