■ Bi-amplification connection

A bi-amplification connection uses two amplifiers for a

speaker. One amplifier is connected to the woofer section

of a loudspeaker while the other is connected to the

combined mid and tweeter section. With this arrangement

each amplifier operates over a restricted frequency range.

This restricted range presents each amplifier with a much

simpler job and each amplifier is less likely to influence

the sound in some way. The internal crossover of the

speaker consists of a LPF (low pass filter) and a HPF (high

pass filter). As its name implies, the LPF passes

frequencies below a cutoff and rejects frequencies above

the cutoff frequency. Likewise, the HPF passes

frequencies above its cutoff.

■ CINEMA DSP

Since the Dolby Surround and DTS systems were

originally designed for use in movie theaters, their effect

is best felt in a theater having many speakers designed for

acoustic effects. Since home conditions, such as room

size, wall material, number of speakers, and so on, can

differ so widely, it is inevitable that there are differences in

the sound heard. Based on a wealth of actually measured

data, Yamaha CINEMA DSP uses Yamaha original sound

field technology to combine Dolby Pro Logic, Dolby

Digital and DTS systems to provide the audiovisual

experience of a movie theater in the listening room of your

own home.

■ Component video signal

With the component video signal system, the video signal

is separated into the Y signal for the luminance and the PB

and P

R signals for the chrominance. Color can be

reproduced more faithfully with this system because each

of these signals is independent. The component signal is

also called the “color difference signal” because the

luminance signal is subtracted from the color signal. A

monitor with component input jacks is required in order to

output component signals.

■ Composite video signal

With the composite video signal system, the video signal

is composed of three basic elements of a video picture:

color, brightness and synchronization data. A composite

video jack on a video component transmits these three

elements combined.

■ Dolby Digital

Dolby Digital is a digital surround sound system that gives

you completely independent multi-channel audio. With 3

front channels (front L/R and center), and 2 surround

stereo channels, Dolby Digital provides 5 full-range audio

channels. With an additional channel especially for bass

effects, called LFE (Low Frequency Effect), the system

has a total of 5.1-channels (LFE is counted as 0.1

channel). By using 2-channel stereo for the surround

speakers, more accurate moving sound effects and

surround sound environment are possible than with Dolby

Surround. The wide dynamic range from maximum to

minimum volume reproduced by the 5 full-range channels

and the precise sound orientation generated using digital

sound processing provide listeners with unprecedented

excitement and realism. With this unit, any sound

environment from monaural up to a 5.1-channel

configuration can be freely selected for your enjoyment.

■ Dolby Digital EX

Dolby Digital EX creates 6 full-bandwidth output

channels from 5.1-channel sources. This is done using a

matrix decoder that derives 3 surround channels from the

2 in the original recording. For the best results, Dolby

Digital EX should be used with movie sound tracks

recorded with Dolby Digital Surround EX. With this

additional channel, you can experience more dynamic and

realistic moving sound especially with scenes with

“fly-over” and “fly-around” effects.

■ Dolby Pro Logic II

Dolby Pro Logic II is an improved technique used to

decode vast numbers of existing Dolby Surround sources.

This new technology enables a discrete 5-channel

playback with 2 front left and right channels, 1 center

channel, and 2 surround left and right channels instead of

only 1 surround channel for conventional Pro Logic

technology. There are three modes available: “Music

mode” for music sources, “Movie mode” for movie

sources and “Game mode” for game sources.

■ Dolby Pro Logic IIx

Dolby Pro Logic IIx is a new technology enabling discrete

multi-channel playback from 2-channel or multi-channel

sources. There are three modes available: “Music mode”

for music sources, “Movie mode” for movie sources (for

2-channel sources only) and “Game mode” for game

sources.
