What's more, when you've been listening on your smartphone outside and come inside, the song immediately streams to your AVR—like magic, you enjoy uninterrupted music.

Purist, Finest Sound

The Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity pre-amplification, anti-vibration technology and independent pure power supplies. All models have a fully discrete power amplifier that helps to minimise distortion.

They also adopt independent pure power supplies and anti-vibration heatsinks. Independent power supplies for the DACs are designed to further eliminate noise on certain models. Down to every detail, these AV receivers are designed with full emphasis on the highest possible sound quality.

Discrete Amp Configuration

This AV receiver was designed with a strong focus on achieving exceptionally high sound clarity. It employs a discrete amp configuration and a low jitter PLL circuit, which contribute to its excellent audio performance.

One-Touch Start

Pressing a SCENE button powers on the AV receiver and selects the input source and DSP mode. You can re-set the buttons for different sources by selecting a source and DSP mode, then pressing a scene button for more than three seconds.

Automatic Speaker Setup

YPAO analyses the room acoustics and adjusts various audio parameters for optimum sound in just a few minutes. It’s like having a professional installer calibrate your system. CINEMA DSP 3D provides a wide, high and dense sound field. HD Audio format decoding lets you enjoy HD Audio sources. Virtual Presence Speaker delivers 3-dimensional sound without actual use of presence speakers.

Virtual Presence Speaker

The Virtual Presence Speaker function makes full use of centre and surround speakers to create virtual presence speakers. Enjoy CINEMA DSP 3D Mode surround sound even in environments where speaker installation is limited. In addition, this model also features a Virtual Surround Back Speaker function.

2-Channel Sound

Zone B output capability allows the receiver to send 2-channel sound to a second zone, so the main zone now has 5-channel output. This means that users can enjoy stereo sound in a second room. The same source will play in both zones (cannot use two sources).

Vibration Free Technology

The Anti-Resonance Technology (A.R.T.) Wedge is a fifth foot in the centre of the unit. It dampens vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers.

Strength and Resistance

The feet of the RX-A670 feature a newly designed, high-density structure which utilises two different kinds of interior ribs — straight and curved — to enhance strength and damping performance. Installation stability is improved and chassis resonance is dispersed, effectively eliminating external vibration. The low-range response is enhanced, while resonance peaks in the mid- and high-range are reduced, providing dynamic sound and focused accurate reproduction.
