Connections

The Phones jack

If you prefer to play with headphones for high quality personal monitoring, plug a
standard stereo headphone set into the rear panel PHONES jack.  The internal speak-
ers are automatically disconnected.

Use the VOLUME slider to adjust the headphone volume.

The Damper jack

An optional footswitch can be plugged into the DAMPER jack for sustain control.
The footswitch operates like the damper pedal of an acoustic piano.  Press for sus-
tain, release for normal sound.

The Aux. Out jack

Connect the rear-panel AUX. OUT jack to amplified speakers, amplifiers or domes-
tic hi-fi units for external amplification.  Use audio cables with standard 1/4" jacks
and plug the other end into the LINE IN or AUX. IN of the external amp. system.  To
use the external amp. system only and exclude the internal speakers of the GK310,
plug a headphones jack into the PHONES jack.

The MIDI IN, MIDI OUT and MIDI THRU ports

The GK310 is fitted with a standard MIDI interface consisting of In, Out and Thru
ports for MIDI connections.

The MIDI IN port receives MIDI data from an external MIDI device.

The MIDI OUT port transmits MIDI data to an external MIDI device.

The MIDI THRU port retransmits the same MIDI data received at the MIDI IN port to
another external MIDI device.

Listen to the Demo Songs

You can listen to the automatic playback of your GK310 to get an idea of what the
instrument is capable of doing.  You can also play along with the demos in playback.

1. Turn the power ON by pressing the [POWER] switch.

After a short period, the display will appear showing the NORMAL playing mode
with a piano sound (Piano1) ready to play across the full keyboard.

2. Set the volume of the instrument as a whole by using the [VOLUME] slider.  A

comfortable level is around the halfway mark.

This control increases or decreases the volume of the internal speakers, the
headphones and the Aux. Out  jack.
