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
15
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.
16
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.
