purest signal quality possible. Pure Direct provides

the shortest possible signal path for two-channel or

multichannel analogue inputs, with no signal

processing and no display. Straight outputs the

original analogue or digital signal without any

post-processing. i.LINK provides a digital

connection for DVD-Audio Linear PCM, Super Audio

CD DSD (Direct Stream Digital) and other high

quality audio sources. Direct provides a direct

connection for analogue stereo/multichannel input

and digital stereo/multichannel (via i.LINK) input,

with a dimmed display.

Symmetrical Power Amplifier Circuitry (RX-Z9)

The High Current Amplification system uses a

symmetrical, full push-pull circuit configuration

with a complementary FET input stage. This ensures

balanced output with no signal interference and

for lower noise and distortion.

Effective Linear Damping

Level variations due to high impedance tend to

reduce an amplifier's damping factor (ability to

control unwanted speaker cone movement at low

frequencies), and frequency variations cause it to

fluctuate. Yamaha's Linear Damping circuit cancels

the effect of these variations, maintaining a high,

stable damping factor for superior sound

articulation and frequency response.

High Grade Construction with Independent

Chambers and Anti-Vibration Design (RX-Z9)

The RX-Z9 uses a heavy-duty, rigid chassis

construction with separate individual chambers for

left and right power amplifiers, power supply and

control section to prevent any chance of

interference. This thick chassis has electromagnetic

shielding. The extremely large aluminium-extruded

heat sinks have anti-resonance characteristics and

ensure effective heat dissipation. Yamaha's

ToP-ART base and feet provide stability and further

vibration-damping. The other receivers use many of

these same design features.

Only the Finest Parts are Used

At this degree of extreme sound quality, each and

every part in the receiver makes a difference.

Yamaha technicians tested, selected and in many

cases custom-designed all parts, and then tested

them in groups to ensure that they sounded good

together. Particularly noteworthy parts, in addition

to the transformer and capacitors, include:

Schottky Barrier diodes that allow fast switching

for high S/N ratio (RX-Z9/RX-V2500).

High performance FE Mica capacitors and Metric

Mylar Film capacitors using polypropylene

material.

Thick PC board wiring with 1.6mm φ diameter

copper jumper cables.

plated crossover connections and shielding.
