QUESTION
ADJUST Are adjustments
required such as the
tuning needed on
acoustic pianos?
HANDLING Do these models require
monitoring the humidity
and temperature during
usage/storage like an
acoustic piano?
SPECS Is the keyboard action
on the DGP7, DGP5 the
same as on the N3, N2?
SPECS Is the keyboard action
on the N3, N2 the same
as on the N1?
OTHERS Does the N1 have two
production numbers?
Tuning is not required. However these models do use the
same wooden keys and action, and felt as acoustic pianos
so adjustment (servicing) is required when the keyboard
operation is stiff due to wear or due to environmental
changes.
There are no strings so the tuning will not deviate and no
large changes in sound being played will occur. However,
the keyboard action uses wooden material the same as an
acoustic piano so maintaining it in the same storage/usage
environment as an acoustic piano is recommended.
They are not exactly the same. The N3 and N2 have an
improved action which is a modifi ed version of that used by
the DGP7, DGP5. The service part numbers on the N3 and
N2 are therefore all completely different numbers.
They are not exactly the same. The N3, N2 are produced
at a different manufacturing plant than the N1 so the key
shutter installation methods are different. Due to this, the
service part numbers are all completely different.
The upper unit and the lower unit are manufactured at
different production plants so they each have different
production numbers. On the upper unit, a production No.
label is attached to the bottom of key bed lower switch box.
On the lower unit, a production No. label is attached at the
bottom inner left of the speaker box.
