Advanced Facilities

Each generation of Yamaha receivers brings an evolution of our popular features while adding innovative enhancements to improve the operating experience. This is why even though our receivers are the most technologically advanced, they remain remarkably easy to use and enjoy. Although these receivers look like formidable machines, you’ll soon appreciate just how convenient and enjoyable they are to use.

YPAO Sets the Best Sound for Your Room — Automatically! (RX-Z9, RX-V2500, RX-V1500,

RX-V757, RX-V657, YHT-840BG and DVX-S150)

YPAO automatically modifies the audio output to provide precisely the best sound for the acoustics of the room. The unit comes supplied with a high precision Optimiser Microphone, which you simply place in the position where you most frequently listen. Activating the YPAO function causes test tones to be emitted from the speakers. These tones are picked up by the Optimiser Microphone and then analysed. Based on the results, a variety of audio parameters are precisely calibrated to optimise the sound at the listening position. You enjoy not only better sound, but the BEST sound for each and every room.

The RX-V2500 has an improved system also adjusts frequency response, and provides three programmed EQ patterns, plus the ability to manually adjust parametric EQ settings. Six YPAO settings can be held in memory and recalled via two system memory buttons on the remote control.

On-Screen Display with GUI and Dedicated

Remote Control (RX-Z9)

The RX-Z9 and RX-V2500 have the best looking and easiest to use on-screen display you’ve ever seen. This is due in part to the high quality video circuitry, which provides sharp, clear images. The GUI (Graphical User Interface) includes extensive yet easily understandable setup menus and has been designed to make it easy to select and adjust desired functions.

And to further simplify operation, The RX-Z9 has provided a second remote control dedicated to GUI use. The large round cursor control in the centre makes it easy to navigate the on-screen menus and enter desired commands. It also has power, volume and mute buttons.

Custom Installation Compatibility

(RX-Z9, RX-V2500, RX-V1500, RX-V757, RX-V657 and RX-V557)

• Multi-Zone Capabilities

These receivers have a variety of features that allow flexible custom installation for enjoying sound in two or three rooms (zones) of your home. The RX-V2500 and RX-V1500 provide audio output to Zones 2 and 3, and the RX-V2500 offers video output (including S-Video) for Zone 2 as well. The RX-Z9/RX-V757/RX-V657/ RX-V557 deliver audio output to Zone 2. Zone 2 power amplifier assignability and speaker terminals mean that Zone 2 can be fully independent with its own 2-channel power, while you still enjoy 5.1-channel sound in the main room (except RX-V557).

• Convenient Control

A switch for selecting Main Zone or Zone 2 power is conveniently located on the front panel (except RX-V1500). All five receivers provide a remote control for Zone 2, and the RX-V2500 also offers Zone 2 and 3 volume control, mute and input selection.

• Other Features

All six receivers include trigger output for automatic powering of other components (RX-Z9/RX-V2500 has two), remote control IR code input and output (RX-Z9/ RX-V2500 has two), and an RS-232C interface for using a PC or touch-screen controller to configure the receiver. They also provide speaker A, B or A+B selection.
