2 GK340 Owners manual
Connections
The Phones jack
If you prefer to play with headphones for high quality perso-
nal monitoring, plug a standard stereo headphone set into
the rear panel PHONES jack. The internal speakers 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 sustain, release for
normal sound.
The Aux. Out jack
Connect the rear-panel AUX. OUT jack to amplified speakers,
amplifiers or domestic hi-fi units for external amplification.
Use audio cables with standard 1/4" jacks and plug 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 GK340, plug a jack into the PHONES jack.
The MIDI IN, MIDI OUT and MIDI THRU
ports
The GK340 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.
