A Living Tradition in Sound
A piano comes into this world through the perfect synergy
of
advanced technical
skill and artistry. Such a piano can create sound that truly reflects the player's
feelings.
The final stage in piano production is called "voicing". It is here that the
instrument is given its soul.
A highly skilled expert concentrates his mind and sensitivity on the sound
of
each
key, finely adjusting the dynamic feel
of
the hammers, bringing the tone and
vibrancy
of
all 88 keys together perfectly; a truly stunning achievement.
It is a quality
of
sound that can only be determined by
an
astute, sensitive ear. We
apply this very same concept to the manufacture
of
our audio products. The
technician performs exhaustive listening tests and every component is considered,
in order to finally achieve the ideal sound.
Yamaha's tradition
of
audio quality stretches back over 125 years, and continues to
Jive
on in all Yamaha products today.

1
Remove approximately 10 mm
of
insulation
from
the
end
of
each speaker cable
and
twist
the
exposed wires
of
the
cable
together
to
prevent
short
circuits.

and then
insert
the
bare
wire
into

When looseningthe knob
of
the speaker terminal, do not rotate it
excessively. Theknob may come

and posethe danger
ofbeing
swallowed by a child.
• Touching the speaker terminal with a metallic rack may cause
short circuit and damage this unit. When installing the unit
in
a
rack, maintain a sufficient clearance to prevent the speaker
terminals from touching the rack.
• To reduce the risk
of
electric shock, do not touch the speaker
terminal when the unit is turned on.

• Bi-wire connection
The hi-wire connection separates the woofer from the
combined midrange and tweeter section. A hi-wire
compatible speaker has four binding post terminals. These
two sets
of terminals allow the speakerto be split into two
independent sections. This split connects the mid and high
frequency drivers
to one set of terminals and the low
frequency driver to the other pair.
Example of a bi-wiring connection (R channel)
Rear panel of A-S2100 Speaker
Caution
To use the hi-wire connections, ~e impedance of each speaker
must be 8 Q
or higher.
Remove the shortingbars or bridges to separate the LPF (low
