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

1 STANDBY/ON, OFF switch

Turns on or off this unit. STANDBY/ON (upper position): In this position,

you can select STANDBY or ON, using the p AMP key on the remote control.

OFF (lower position): The power of this unit is

turned off.

Notes

• 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.

2 STANDBY/ON indicator

Lit brightly: Shows that the power of the unit is ON.

In this condition, you can switch the unit to STANDBY mode by pressing the p AMP key on the remote control.

Lit dimly: Shows that the unit is in STANDBY mode.

In this condition, you can switch the unit on by pressing the p AMP key on the remote control.

Off: Shows that the power of the unit is OFF. In this

condition, you can turn the power on only by pressing the STANDBY/ON, OFF switch on the front panel.

3 PHONES jack

Outputs audio for private listening with headphones.

Notes

• 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.

AUDIO MUTE

VOLUME

PHONO

Adjusts the volume level when headphones are plugged in to avoid sudden changes in volume. Choices: –6 dB, 0 dB, +6 dB, +12 dB

5 SPEAKERS selector

Turns on or off the sets of speakers connected to the SPEAKERS L/R CH A and/or B terminals on the rear panel, as follows.

OFF: Both sets of speakers are off. A/B: The set of speakers connected to the A or B

terminals is on.

A+B BI-WIRING: Both sets of speakers are on.

6 METER selector

Switches the display of the meter to OFF, PEAK or VU.

OFF: Turns off the meter and the illumination. PEAK: Switches the meter to a peak level meter. The

peak level meter shows a momentarily highest audio output level.

VU: Switches the meter to a VU (Volume Unit) level

meter. The VU level meter shows an effective audio output value that is similar to human senses.

7 Meter displays (LEFT/RIGHT)

Show the audio output level of the left (LEFT) and right (RIGHT) channels in VU or PEAK meter mode. The VU or PEAK meter can be selected by the METER selector.

8 BASS control

Increases or decreases the low frequency response. The 0 position produces a flat response. Control range: –10 dB to +10 dB

9 TREBLE control

Increases or decreases the high frequency response. The 0 position produces a flat response. Control range: –10 dB to +10 dB

0 BALANCE control

Adjusts the audio output balance of the left and right speakers to compensate for sound imbalances caused by speaker locations or listening room conditions.

Notes

• When both the BASS and TREBLE controls are set to the 0 position, audio signal bypasses the tone control circuitry.

• The BASS, TREBLE and BALANCE controls do not affect the signals input at the MAIN IN jacks and signals output at the LINE 2 REC jacks.

Caution

If you use two sets (A and B), the impedance of each speaker must be 8 Ω or higher.

Notes

• 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 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.

Notes

• Because the power amplifier of A-S2100 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.
