IV. Calibration
The keyboard adjustment must be performed after installing the QuietTime GT-2 system in the piano.
The reason for this requirement is that the control unit of your GT-2 needs to keep travel data of each key, measured
from the rest position of the key.
CAUTION !
If the calibration is not performed, few, if any, of the keys will work correctly. It may be necessary to perform the
calibration again, whenever there is any change in height of the key or key deformation.
How to calibrate the keys

The keyboard cable and the AC power adapter should be plugged into the QuietTime GT-2 control unit and the
power should be switched off.

The mute lever should be in Mute position.

Make sure that nothing is sitting on the keyboard that might press a key down.

While holding the [Metronome]-button, turn on the GT-2.

Release the [Motronome]-button after three seconds. (wait till the light next to “Sound” is lit)

After about five seconds, the display looks as shown below
14

Press each of the 88 keys, one at a time, all the way down, with medium force and speed.

After you have finished pressing all of the keys, press the [Metronome]-button again to finish the calibration.
It will take a few seconds for the data to be stored in permanent memory.

When the data is successfully stored, the display will change as shown below and the piano is ready to play again.
15
The calibration procedure on the previous pages should make all of the keys equally sensitive.
If you find that some keys still play too loudly or softly, use the following procedure to adjust the sensitivity of
individual keys.
Adjustment of individual keys



Make sure the GT-2 system is switched off.
While holding the [Record]-button down, turn the GT-2 system on.
After 3 seconds, release the [Record]-button.

The display should look as shown below.
While wearing the headphones for monitoring the sound, play each key and listen to the volume of the sound. If
the sensitivity needs to be adjusted, use the [Data]-buttons to adjust the sound volume for the key that you played
at last. Adjust the sensitivity up and down till it matches the other keys.
The display shows the current key’s sensitivity value from 000 to 255.
When moving to a different key, the last displayed value for the previous key is remembered.
When all keys requiring adjustment have been done, press the [Record]-button again to end the key adjustment.
16
It will take a few seconds for the adjustment data to be stored in permanent memory.
When the adjustment data is successfully stored, the display will change as shown below and the piano is ready to play
again.
17
V. Connecting to external Equipment
Connecting GT-2 to external Audio Equipment
Use two audio cables to connect the Left and Right Audio outputs of the GT-2 system to inputs of your audio system.
The provided signal is a: „unbalanced, line level“-signal.
See the diagram below, which is representative for a club or a performance hall audio system.
You may also connect an external audio source, such as a CD player, to the audio inputs of the GT-2. Using two audio
cables, connect the Aux or Line output of your source to the Left and Right Audio inputs of the GT-2. The sound in the
GT-2 headphones will now be a mixture of the piano sound and the external source sound. Use the volume control at
the external source to adjust the external sound source volume.
18
Connecting GT-2 to external MIDI Equipment.
In order to send MDI data to a General MIDI synthesiser or a computer, connect a MIDI cable between the MIDI OUT
port of the GT-2 and the MIDI IN port of your synthesiser or computer. See the drawing below.
Note:
Most computers do not have a MIDI interface built-in. You may need to add a MIDI interface to your computer
before you can connect it to your GT-2 system. In order to receive MIDI data from a General MIDI keyboard,
synthesiser or computer, connect a MIDI cable between the MIDI Out port of the external device and the MIDI In
port of the GT-2.
See the drawing below.
 You may connect MIDI In and Out cables at the same time.
If connecting to a computer, be sure to turn off „Pass Through“ in your software to avoid “double notes”.
 Although only Piano and Church Organ sounds are available from GT-2’s keyboard, several additional sounds
are available when connected to an external MIDI source.
