Setting Up

PSR-I425 Owner’s Manual

Make all necessary connections below BEFORE turning the power on.

The PSR-I425 speakers are automatically shut off when
a plug is inserted into this jack.

The PHONES/OUTPUT jack also functions as an exter-
nal output. You can connect the PHONES/OUTPUT
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.

The sustain function lets you produce a natural sustain
as you play by pressing a footswitch. Plug the Yamaha
FC4 or FC5 footswitch into this jack and use it to switch
sustain on and off.

Connect the instrument’s USB terminal to the USB ter-
minal of a computer, and you can transfer performance
data and song files between the two (page 86). To use
the USB data-transfer features you’ll need to do the fol-
lowing:

• First, make sure the POWER switch on the instru-

ment is set to OFF, then use a USB cable to con-
nect the instrument to the computer. After making
the connections, turn on the power of the instru-
ment.

• Install the USB MIDI driver on your computer.

Installation of the USB MIDI driver is described on
page 94.

Turn down the volume by turning the [MASTER VOL-
UME] control to the left and press the [STANDBY/ON]
switch to turn on the power. Press the [STANDBY/ON]
switch again to turn the power OFF.

Backup data in the flash memory is loaded to the instru-
ment when the power is turned on. If no backup data
exists on flash memory, all instrument settings are
restored to the initial factory defaults when the power is
turned on.

Connecting Headphones (PHONES/OUTPUT Jack)

Connecting a Footswitch (SUSTAIN Jack)

• Avoid listening with the headphones at high volume for long peri-

ods of time; doing so may not only result in ear fatigue, it may be
damaging to your hearing.

WARNING

• To prevent damage to the speakers, set the volume of the external

devices at the minimum setting before connecting 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 gradually raise the volume controls while
playing the instrument to set the desired listening level.

CAUTION

• Make sure that the footswitch plug is properly connected to the SUS-

TAIN 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.

NOTE

Connecting to a Computer (USB Terminal)

Turning the Power On

• Make sure to purchase a quality USB cable at a musical instrument

store, computer store or electrical appliance store.

NOTE

• Even when the switch is in the “STANDBY” position, electricity is

still flowing to the instrument at the minimum level. When you are
not using the instrument for a long time, make sure you unplug the
AC power adaptor from the wall AC outlet, and/or remove the bat-
teries from the instrument.

CAUTION

• Never attempt to turn the power off when a “WRITING!” message

is shown in the display. Doing so can damage the flash memory
and result in data loss.
