Accessory Jacks■ Using Headphones• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • •
For private practicing and playing without disturbing others, connect a set of ste-
reo headphones to the rear panel PHONES/OUTPUT jack. Sound from the built-
in speaker system is automatically cut off when you insert a headphone plug into
this jack.
■ Connecting a Keyboard Amplifier or Stereo System • • • • • • •
Though the PSR-172/170 is equipped with a built-in speaker system, you can also
play it through an external amplifier/speaker system. First, make sure the PSR-
172/170 and any external devices are turned off, then connect one end of a stereo
audio cable to the LINE IN or AUX IN jack(s) of the other device and the other
end to the rear panel PHONES/OUTPUT jack on the PSR-172/170.
■ Using a Sustain Footswitch • • • • • • • • • • • • • • • • • • • • • • • • •
This feature lets you use an optional footswitch (Yamaha FC4 or FC5) to sustain
the sound of the keyboard voice. This is used in the same way as a damper pedal
on an acoustic piano — press and hold down the footswitch as you play the key-
board to sustain the sound.
■ Using the MIDI Terminals • • • • • • • • • • • • • • • • • • • • • • • • • • •
The PSR-172/170 also features MIDI terminals, allowing you to interface the
PSR-172/170 with other MIDI instruments and devices. (For more information,
see page 52.)
• To prevent damage to the
speakers, set the volume of the
external devices at the mini-
mum setting before connect-
ing them. Failure to observe
these cautions may result in
electric shock or equipment
damage. Also, be sure to set
the volumes of all devices at
their minimum levels and grad
-
ually raise the volume controls
while playing the instrument to
set the desired listening level.
• Make sure that the footswitch
plug is properly connected to the
SUSTAIN jack before turning on
the power.
• Do not press the footswitch while
turning the power on. Doing this
changes the recognized polarity
of the footswitch, resulting in
reversed footswitch operation.
