FEATURES & TECHNOLOGY
High Sound Quality
|
|
192kHz/24-Bit DACs for All Channels
Yamaha amplifiers / receivers use extremely high performance 192kHz/24-bit digital-to-analog converters for all 10 channels. They perform accurate sound field reproduction for high quality multi-channel sources, and for two-channel stereo, provide outstanding separation and precise musical delineation. They deliver superior low level linearity with excellent full-scale performance under varying operation conditions.

Accurate Touch Volume Control
No one expects more from a volume control than up and down — except Yamaha. We decided that controlling the volume could be made both easier and more accurate, and the result is the Accurate Touch Volume Control. It lets you make delicate adjustments within a narrow range, yet enables you to move to very high or low levels more quickly. Its extreme accuracy, with negative gang error of less than 0.5dB, due to a high-signal-resolution analog design in conjunction with an ultra-precise digital control circuit (Yamaha original YAC-520 and YAC-523 LSIs) for all channels. The wide control range extends from –80dB to +16.5dB, with narrow 0.5dB steps throughout the entire range for delicate control, even at low volumes.

Anti-Resonance Alumite-Finish Heat Sinks
The large, anti-resonance, aluminum-extruded and black anodized heat sinks have an alumite finish and are located on the base frame with the power amplifier circuit boards to prevent interference with the preamplifier and digital processing sections. The power block is equipped with a fan, but it is only used for extreme heat build-up and is not activated during normal operation, preventing the occurrence of even the slightest unwanted noise.

|
Anti-Resonance ToP-ART Base
Supporting the heavy heat sinks, transformer, and circuit board is Yamaha’s ToP-ART base, which has exceptional anti-resonance and damping characteristics. Beneath this base is the bottom of the power amplifier, part of the heavy chassis which is also designed for maximum vibration damping.

|
Detachable Power Cable
The Detachable Power Cable is separate, rather than attached to the unit. It is a thicker type than usual, for higher power handling capacity (Not available in some areas).

|
Digital ToP-ART
Digital ToP-ART (Total Purity Audio Reproduction Technology) is the name Yamaha has given to a design philosophy whose goal is to maximize digital quality while minimizing analog circuitry. The culmination of Yamaha’s long experience in digital engineering and design, it brings together several key elements to create the best-sounding, A/V components available on the market.

|
|
Direct Stereo
Direct Stereo causes the input stereo signal to bypass the DSP circuitry so the pure signal is output without any processing or data loss whatsoever.

|
Finest Parts Used Throughout
In order to realize the goals of massive power and superlative sound quality, Yamaha technicians completely re-evaluated all the parts used in previous receivers. As a result, many were replaced with more expensive or custom-designed units.

|
|
High Dynamic Power Capability
These amplifiers / receivers are capable of delivering large amounts of reserve power for accurate reproduction of the high energy peaks that are especially prevalent in digital audio sources. This emphasizes the music’s dynamic qualities and provides a sharper sound image.
|
|
|
Linear Damping
Level variations due to high amp impedance tend to reduce an amplifier’s damping factor, and frequency variations cause it to fluctuate. This circuit cancels the effect of these variations, maintaining a high, stable damping factor, for superior articulation of all sounds and better frequency response.
|
|
|
Pure Direct
Pure Direct is a special listening mode that provides the highest possible signal purity. It can be used for both analog and digital sources, with two-channel or multi-channel inputs. When it is selected, the signal follows the most direct path and power to the video circuit is shut down. Certain functions are not operational and even the display is turned off, lighting for only a few seconds when a function is used.
|
|
|
Straight and 2-Channel Stereo
Yamaha amplifiers / receivers also offer two other special operation modes for higher quality. Straight outputs the original analog or digital signal without any post-processing. 2-Channel Stereo processes the multichannel signal and outputs it via two channels, for use with a two-speaker system.

|
Wide-Range Frequency Response for DVD-Audio and Super Audio CD
With an extremely wide frequency range of 10Hz to 100kHz, these receiver are capable of delivering the full potential of the new digital audio sources DVD-Audio and Super Audio CD.

Yamaha High Current Amplification
Although power rating is often the first thing customers look at in a receiver, high power output does not necessarily mean good sound. High current level is a much more important factor. Yamaha receivers has always had fairly high current levels, but with the Yamaha amplifier / receivers, we have further improved this performance. In brief, Yamaha High Current Amplification achieves 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.
