DC (9–12V) IN Jack
The DC output cord from the optional
Yamaha PA-4/ PA-40 Power Adaptor
should be plugged in here when the
PSR-48 is to powered from the AC
mains supply (refer to “Power Supply”
on page 4 for more details).
HEADPHONES/
AUX. OUT Jack
A standard pair of stereo headphones
can be plugged in here for private
practice or late-night playing. The
internal speaker system is automati-
cally shut off when a pair of
headphones is plugged into the
HEADPHONE jack. The HEAD-
PHONES/ AUX. OUT jack can also be
used to deliver the output of the PSR-
48 to a keyboard amplifier, stereo hi-fi
system, mixing console or tape
recorder. (refer to page 55)
*Use a relatively low MASTER
VOLUME control setting when
connecting the PSR-48 to a stereo
sound system. Use the stereo
system’s volume control to adjust
volume.
MIDI IN and OUT Connectors
The MIDI IN connector receives MIDI
data from an external MIDI device
which can be used to control the PSR-
48. The MIDI OUT connector transmits
MIDI data generated by the PSR-48
(e.g. note and velocity data produced
by playing the keyboard).
More details on MIDI are given in “MIDI
FUNCTIONS” on page 45.
