QRS
is
pleased
that
you
have
chosen
the
QRS
PNOma on
II™
Retro
fi
t
Kit,
the
superb
retro
fi
t
kit
for
automa ng
acous c
pianos.
This
product
brings
a
level
of
excellence
in
reproducing
live
performances
on
the
piano.
It
is
made
possible
by
many
remarkable
technical
innova ons.
However,
in
spite
of
its
high
level
of
sophis ca on,
this
retro
fi
t
kit
is
easy
to
install
and
service.
Before
beginning
the
installa on,
take
me
to
read
“Make
Certain
the
Kit
Fits,”
to
ensure
that
the
piano
will
indeed
accept
the
kit.
This kit will NOT fit into a spinet piano.
Familiarize
your
‐
self
with
the
parts
in
the
kit
before
proceeding
and
then
let
the
instruc ons
guide
you.
All
piano
keys
have
a
tendency
to
react
di
ff
erently.
The
key
solenoids
provide
three
adjust
‐
ments:
the
fi
rst
adjusts
the
amount
of
plunger
throw
to
match
that
of
the
key
‐
tail
li ,
the
sec
‐
ond
sets
the
lost
mo on
between
the
key
tail
and
the
plunger
p
and
the
third
adjusts
the
force
of
each
key
solenoid.
Although
the
kit
has
been
provided
with
enough
solenoids
to
play
80
notes,
the
instrument
has
been
designed
to
support
the
en re
88
‐
note
range
of
the
modern
piano.
The
addi onal
parts
required
may
be
purchased
separately
if
an
88
‐
note
installa on
is
desired.
The
standard
Pianoma on
kit
comes
with
a
pedal
solenoid
but
will
also
run
in
magic
pedal
mode
if
the
Pedal
Solenoid
is
not
present.
The
pedal
solenoid
is
connected
to
the
power
supply
by
a
4
posi on
plug.
The
Pedal
Solenoid
will
ac vate
the
trapwork,
therefore
li ing
the
damp
‐
ers
o
ff
of
the
strings
as
a
real
pianist
would.
In
“Magic
Pedal
Mode”
the
key
solenoids
control
the
sustain
events
by
extending
note
dura ons
to
the
corresponding
pedal
ON
event.
The
instrument
uses
rela vely
low
voltages
supplied
by
an
isola on
transformer.
Low
voltages
eliminate
the
danger
of
electrical
shock
to
the
installer
(Below
UL
limit
of
41V).
The
electronics
are
fully
shielded
to
prevent
electromagne c
interference.
You
will
need
some
materials
not
provided
with
the
kit
to
complete
the
installa on.
Steinway
grand
pianos
require
special
Sostenuto
trapwork
not
supplied
with
the
standard
kit.
