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.

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

In this position, you can select STANDBY or ON,
using the pAMP key on the remote control.
OFF (lower position):
The power of this unit is turned off.
• When you turn on this unit, it will take a few seconds
before this unit can reproduce sound.
• If you disconnect the power cable from the AC outlet and
connect it again when this unit is in STANDBY mode, the
power of the unit is turned on. If the unit is not to be
operated for a long time, set the STANDBY/ON/OFF
switch to OFF.
2STANDBY/ON indicator
Lit brightly:
Shows that the power of the unit is ON. In this
condition, you can switch the unit to STANDBY mode
using the pAMP key on the remote control.
Lit dimly:
Shows that the unit is in STANDBY mode. In this
condition, press the pAMP key on the remote control
to turn on the unit.
Off:
Shows that the power of the unit is OFF. In this
condition, you can turn on the unit using the
STANDBY/ON/OFF switch only.
3PHONES jack
Outputs audio for private listening with headphones.
• When headphones are plugged in:
– Both speaker sets connected to the SPEAKERS L/R CH
terminals are turned off.
– No signals are output at the PRE OUT jacks.
– You cannot select MAIN DIRECT as the input source.
• If headphones are plugged into the PHONES jack while
MAIN DIRECT is selected as the input source, no audio is
output at the PHONES jack.
4TRIM selector
Adjusts the volume level when headphones are
plugged in to avoid sudden changes in volume.

Connections
• 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.

• 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.

■Connecting the speakers
1Remove approximately 10 mm (0.4 in) of
insulation from the end of each speaker
cable and twist the exposed wires of the
cable together to prevent short circuits.
2Unscrew the knob and then insert the bare
wire into the hole.
3Tighten the knob.
• 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.
■Connecting the banana plug
(Except for Europe models)
First, tighten the knob and then insert the banana
plug into the end of the corresponding terminal.
■Connecting the Y-shaped lug
1Unscrew the knob and then sandwich the Y-
shaped lug between the ring part and base.
2Tighten the knob.

■Bi-wire connection
The bi-wire connection separates the woofer from the
combined midrange and tweeter section. A bi-wire
compatible speaker has four binding post terminals. These
two sets of terminals allow the speaker to 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 (L channel)
To use the bi-wire connections, the impedance of each speaker
must be 8 Ωor higher.
Remove the shorting bars or bridges to separate the LPF (low
pass filter) and HPF (high pass filter) crossovers.
y
To use the bi-wire connections, switch the SPEAKERS selector
to the A+B BI-WIRING position.
■Connecting the power cable
Plug the power cable into the AC IN inlet when all
connections are complete, and then plug in the power
cable to the AC outlet.
