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
