Yamaha presents advanced solutions for

maximum home theatre enjoyment.

Yamaha has taken home theatre audio technologies to new levels of achievement.

Long world-renowned for our CINEMA DSP surround sound technology.

Here's a brief introduction to our major technologies.

Highest Sound Quality

Yamaha has a genuine commitment to providing

absolutely the finest sound quality possible in every

component we create. With over a century of

experience in sound production (we made our first

reed organ in 1887) and our status as a world

leader in acoustic and electronic musical

instruments, we are passionate about creating and

reproducing sound in the most beautiful and

natural way. Over the years, with each new series

of receivers, we have improved and refined audio

performance, and Yamaha Digital Home Theatre

Receivers maintain this tradition with an impressive

array of technology and features.

Digital ToP-ART Concept

Digital ToP-ART (Total

Purity Audio Reproduction

Technology) is a Yamaha

product development philosophy that combines

advanced digital engineering and circuit design to

maximise audio signal purity. It is used in three

sections of the receiver, the High Performance Digital

Circuitry and High Current Amplification (explained

below) and the High Definition CINEMA DSP circuitry

(explained on p.16), each of which employs the

world's highest grade parts and most sophisticated

LSIs. Digital ToP-ART enables Yamaha receivers to

deliver superb sound quality and bring out the full

potential of Yamaha's amazing CINEMA DSP

technology.

High Performance Digital Circuitry (RX-Z9)

This section exemplifies the Digital

ToP-ART concept of maximising the quality of the

digital circuitry while minimising analogue circuitry,

and also maintains a straight and logical circuit

layout for optimum signal purity. It includes a variety

of sophisticated technology, beginning with Burr-

Brown 192kHz/24-bit digital-to-analogue converters

for all channels with DSD (Direct Stream Digital)

compatibility. Accurate-Touch Volume Control LSIs

(Yamaha YAC520) are also used for all channels. The

Best Surround Realism

digital bass and treble tone controls have turnover

frequencies for the front L/R and centre channels.

Eight-channel analogue input signals are processed

by 96kHz A/D conversion for highest quality. All

circuitry is on a four-layer processing board in a

fully shielded cabinet for reduced digital

interference.

High Current Amplification

Although power rating is often the first thing

people look at in a receiver, high power output does

not necessarily mean good sound. High current

level is a much more important factor, so Yamaha

developed the High Current Amplification system,

which overcomes two problems common to

ordinary receivers. The first is a difference in

voltage between the power supply and amplifier

circuits caused by current fluctuations. This was

solved by using custom-made, high-grade block

electrolytic capacitors and a copper grip for one-

point grounding. Another current drop is generally

seen between the amplifier circuit and the speaker

terminals, caused by the cables, speaker output

relays, copper circuit boards, and so on. To avoid

this problem, we used an extra-large, low-

impedance toroidal transformer and gold-plated

speaker relay contacts. As a result, Yamaha

receivers achieve low impedance, high current

power from input (power supply circuit) to output

(speaker terminals). This drives the speakers much

more smoothly and dynamically, for better sound

from all sources, including 2-channel audio.

Choice of Signal Paths for Optimum Quality

Yamaha receivers give you a choice of specialised

signal paths, ensuring that you can obtain the
