English Notes ● Connecting a turntable A turntable cannot be connected to this unit directly. Use a commercially available phono equalizer amplifier to connect a turntable to this unit, or connect a turntable incorporated with a phono equalizer amplifier. Notes ● When playing an ordinary CD on this unit following playback of a CD or an LD encoded with DTS, some operations, such as resetting the input selector keys, may be required. ● Even if connected to this unit with a digital connection, some CD, LD, and DVD players may make this unit fail to decode DTS or produce noise. This is because certain digital output data processing by such a player results in DTS-encoded data errors that cause playback failure although the same data processing may cause only a slight change in volume or in frequency response in normal digital sound. ● When an error occurs in the player’s digital output data during playback of an LD or CD encoded with DTS, playback may be disrupted. If this occurs, stop playback and repower the player. ● When digital sound signals from the computer are played, errors in WAVE signals, etc. may occur resulting in noise or a playback failure.

With its stylish, vertical design, this unit allows you to use various audio sources, including your computer, CD player, MD or tape deck, as shown below. Although this unit can be used as part of a typical hi-fi system, connecting it to your computer via the USB terminal, and running the supplied Application Software, allows you to remotely control this unit from your computer and edit the sound field programs.

English This unit cannot be connected with speakers directly. Connect this unit to speakers with a built-in amplifier, a mini-component system, etc., or connect this unit to speakers via a power amplifier. Right speaker E-3  OUTLINE OF THIS UNIT Virtual 3D Surround sound typically requires several speakers situated in front of and behind the listening position, which requires a substantial amount of space that may not always be available. This unit uses Yamaha’s unique “Virtual 3D (three-dimensional)” technology to simulate a typical surround sound system using only two speakers. Virtual FL C FR 3D, which is used by this unit’s sound field programs, simulates the surround effect provided by rear and center speakers, creating “virtual” surround speakers, as shown, so even with only two front speakers, you can still enjoy surround sound. FL C FR Virtual speakers RL RR RL Typical surround system RR Virtual 3D Digital Sound Field Processing (DSP) When you listen to a performance in a concert hall, jazz club, or other live music venue, you not only hear the direct sound coming from the musical instruments and singers, but also the “early reflections” and natural reverberation. Early reflections are the initial sound waves that bounce off the floor, ceiling, and walls. Natural reverberation is made up of sound waves that gradually attenuate as they bounce repeatedly off multiple surfaces. Since the way you hear early reflections and reverberation depends on the shape and size of the building as well as the material and construction of the walls and ceiling, each venue has its own unique “sound,” called its “sound field.” At Yamaha, we have measured all the elements that make up a typical sound field—direction and level of the reflections, band-width characteristics, and delay times—at famous concert halls and opera houses around the world. The information gained in this process has been converted into programs that can be reproduced using Yamaha’s DSP technology. Using its on-board DSP, this unit can process any audio source and recreate the atmosphere of the original venue.
