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
live on in all Yamaha products today.

◆ Full floating and balanced circuit design achieves the full potential of

analogue amplification

An entirely new floating and balanced power amplifier achieves complete symmetry and permits full balanced
transmission (amplification) from the input jack to just before the speaker jack.

◆ Full-stage balanced signal transmission

The integrated amplifier offers full stage balanced transmission, combining high power output with good sound texture
and outstanding S/N performance.

◆ Parallel volume and tone control

◆ Large power supply with four separate circuits

◆ Left-right symmetrical design with rigid, stable construction

◆ Discrete phono amplifier

◆ High-quality headphone amplifier with low-impedance drive

Caution

• Do not let the bare speaker wires touch each other or do not let

them touch any metal part of this unit. This could damage this
unit and/or the speakers.

• All connections must be correct: L (left) to L, R (right) to R,

“+” to “+”, and “–” to “–”. If the connections are faulty, no
sound will be heard from the speakers, and if the polarity of the
speaker connections is incorrect, the sound will be unnatural
and lack bass. Also, refer to the owner’s manual for each of
your components.

• Use RCA unbalanced cables to connect other components
except speakers. Use XLR balanced cables to connect a CD
player or network player with XLR balanced output jacks to the
BAL 1 or BAL 2 jacks of this unit.

• Connect your turntable to the GND terminal to reduce noise in
the signal. However, you may hear less noise without the
connection to the GND terminal for some turntables.

Caution

• Because the power amplifier of A-S3000 is of the floating balanced type, the
following types of connections are not possible.
– Connecting with the left channel “–” terminal and the right channel “–” terminal

as well as “+” terminals (Fig. 1).

– Connecting with the left channel “–” terminal and the right channel “–” terminal

inverted (cross connection, Fig. 2).

– Deliberately connecting with the left/right channel “–” terminals and metal part

on the rear panel of this unit, as well as accidentally touching them.

• Do not connect your active subwoofer to the SPEAKERS L/R CH terminal.
Connect it to the PRE OUT jacks of this unit.

• Do not connect a component with no volume control, such as a CD player, to the
MAIN IN jacks, as the volume level of the signals input to the MAIN IN jacks is
fixed. If such equipment is connected, a sound may burst, and the unit and/or
speaker may be damaged.

3 Tighten the knob.

Caution

• When loosening the knob of the speaker terminal, do not rotate
it excessively. The knob may come off and pose the danger of
being 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.
