PianoDisc Identification & Loudness
By John Dewey

In 991206 MMDigest Dan Armstrong says the lady complains of her
PianoDisc system being too loud.  There are technicians out there who
could give a better answer to his problem but I will give mine.

What model PianoDisc is it?  The order of manufacture is model 1000,
32, 128, 128+ (called 128 plus), 128+ with silent drive, in that order.

If it is a model 1000 or a 32 with the pigtail power supply there
isn't much you can do to lessen the force which the hammers strike the
strings with.  Your best hope is to do things to quiet the sound, such
as voicing the hammers, putting a cover on the strings, putting sound
deadening under the sound board (be careful to not close off
ventilation to the PianoDisc complements), etc.

If it is a model 32 with plug-in power supply, a 128, a 128 plus, or
a piano CD and non silent drive you can do quite a bit to soften the
volume. If it is a 128 plus, or piano CD and silent drive you should be
able to make it so soft that the action noise is louder than the music.

This is a hardware and software adjustment and I would suggest you
talk to someone in your area who is familiar with servicing PianoDisc.
If you don't know who the technicians in your area are you can call
PianoDisc at 1-800-566-3472.  I have found them to be very helpful.

Definitions:

 - pigtail power supply: Power supply has wires a few inches long
with quick couplers on them coming out of the power supply. You plug
the various components into these pigtails.

 - plug-in power supply: Has places to plug in various components,
like your computer does.

 - rail cover: Long metal box under the key bed in line with the back
of the keys that goes all the way across the piano

 - silent drive:  To tell if you have a "silent drive" piano look for
the cover plate on the back side near the bass end of the rail cover,
where the power supply and control box plug in.  If the cover plate is
about 5 inches long it is not silent drive; if the cover plate is about
12 inches long it is silent drive.

This is a very simplified overview and I strongly suggest you contact
a PianoDisc technician if you are not familiar with PianoDisc servicing.
If I can be of any more help please feel free to contact me.
