Yamaha presents advanced solutions for maximum home theater enjoyment.

Yamaha has taken home theater audio and video technologies to new levels of achievement. Long world-renowned for our CINEMA DSP surround sound technology, we now offer both projectors and plasma display monitors for superlative visual enjoyment as well. 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 Theater 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 maximize 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.18), 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 maximizing the quality of the digital circuitry while minimizing analog 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-analog converters for all channels with DSD (Direct Stream Digital) compatibility. Accurate-Touch Volume Control LSIs (Yamaha YAC520) are also used for all channels. The

digital bass and treble tone controls have turnover frequencies for the front L/R and center channels. Eight-channel analog 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.
