Reverberation

Direct sound

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

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.

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.

Setting USB channel

Typical USB audio features multi-channel modes, such as four-channel and six-channel modes, in addition to a normal two-

channel (stereo) mode. This unit is compatible with each of these modes. When a multi-channel mode is selected, you can

receive surround sound of computer games compatible with the 4ch Direct Sound 3D and the surround sound (5.1 channels)

of DVD video on this unit via the USB connection and enjoy it as virtual surround sound.

Note that some operating systems and software programs are not multi-channel compatible. Yamaha websites list the names

of multi-channel compatible operating systems and software.

Notes

●

MacOS9 does not support this feature. Only the two-channel mode can be used. Some versions of Windows also do not support the six

and/or four-channel modes. You can refer to the following Yamaha website for details and related information.

Adjusting the virtual 3D effect

The surround sound effect of the virtual 3D sound field is affected by the room configuration and the position of the listener,

resulting in sound unique to each environment. The procedure below shows you how to adjust the effect of the virtual 3D to

suit your preferences and environment.

Select the VIRTUAL tab at the bottom of the Main Panel. The following screen appears.

1 Balance adjustment

You can adjust the volume balance between the right

and left speakers.

characteristics.

4 Test tone

You can output a test tone successively from the

speakers at their current positions, allowing setting and

adjustment while listening to the tone.

Adjusting the dynamic range

You can set the dynamic range for playing a source with Dolby Digital decoded. This is especially effective for low-volume

listening. Select the D-RANGE tab at the bottom of the Main Panel. The following screen appears.

1 Dynamic range setting

Select the dynamic range for playing a source with

Dolby Digital decoded from MIN, STANDARD, and

MAX. The MAX setting provides a dynamic range of a

movie theater while MIN provides a dynamic range

suitable for late night, low-volume listening.

2 Dynamic range adjustment

This setting becomes available when you choose

STANDARD for the dynamic range. This adjusts high-

level cut scale (H-LEVELCut) and low-level boost scale

(L-LEVELBST), allowing you to freely adjust the

dynamic range between MAX and MIN.

Operating the graphic equalizer

The 7-band graphic equalizer allows you to set the frequency characteristics according to the type of the music that is played

and to compensate for the room characteristics and the speakers’ frequency characteristics.

This panel is always shown when no DSP sound field program is selected. When a DSP sound field program is selected,

selecting the EQUALIZER tab at the bottom of the Main Panel will show this panel.

ADVANCED OPERATION

Setting adjustment on the Setup panel

When you click SETUP of the Main Panel, the Setup panel appears, allowing you to perform the following settings.

USB Setting

m USB Multi-Channel Setting (for Windows only)

This allows you to select the number of channels for

sending playback signals via the USB connection from

two, four, and six channels. (Note that you cannot

record signals from the USB connection on the

computer when six channels are selected.)

Custom Keys

m Skin Selection

This allows you to select the skin (the design of the

background picture of the Application Software) from

several preset patterns.

m Setting Remote Control Custom keys

This allows you to store a set of commands (input

selector, sound field program, volume setting, etc.) to

each of the A, B and C keys on the remote control. After

storing, simply pressing each key will execute the

stored command.

Note

The screen design, functions, etc. are subject to change

due to software upgrades. For details, refer to the

Online Help of the Application Software.

Edit Names of Input Sources

You can assign a name consisting up to seven characters

to each input source. For example, if a tape deck is

connected to the AUX 1 terminals, you can change the

name, AUX 1, to TAPE. As this name change information

is sent to the main unit, the display on the main unit

changes accordingly.

Volume Settings

m USB Mix

When USB Mix is on, even if signals received at input

terminal(s) other than the USB terminal when it is

selected, you can mix the input signals from that

selection with the signals from the computer via the

USB connection and play the mixed signals. For

example, while you are listening to music from the tape

deck connected to AUX 1, mail arrival beeps and

warning beeps are also available.

Clicking the check box to enter the check mark in the

box will turn on the USB Mix. This status allows you to

adjust the volume level of the signals from the USB

connection. (As this adjusts the volume balance

between the selected input signals and the input signals

from the USB connection, it does not affect the volume

when USB is selected by the input selector keys.)

Clicking the check box to delete the check mark will turn

off the USB Mix. In this status, the signals from the USB

connection can be played only when USB is selected by

the input selector keys.

m Maximum Volume Setting

When adjusting the volume on the Application Software,

you may inadvertently turn up the volume too high. To

avoid this, you can use this function to set a maximum

volume for the Application Software.

m Digital Volume Setting

This allows you to digitally turn up and down the volume

in the DSP. Take care not to turn up the volume when

the level of the digital input signal is high as it may

cause sound distortion due to digital processing. If

sound distortion occurs, turn down the volume.
