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.

Highest Sound Quality
Every Yamaha receiver gives you
maximum home theater performance!
Yamaha receivers are designed and built to deliver nothing less than maximum performance: the
highest sound quality, the highest picture quality, and the best surround realism, all with the
easiest possible operation. Whichever model you choose, we’re confident that it will totally satisfy
your highest expectations for home theater enjoyment.
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
specialized signal paths, ensuring that you
can obtain the purest signal quality possible.
Pure Direct provides the shortest possible
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.
