Dolby Pro Logic Surround
Surround system
Since the TX-SV424 is equipped with a front amplifier, center amplifier and a rear (surround) amplifier, Dolby Pro Logic Surround effects
can all be produced. When you using video cassette tapes or video discs that have the DOLBY STEREO or DOLBY SURROUND trade
mark, you can enjoy the feeling of a movie theater in your own room. When reproducing these effects, placement of the rear (surround)
speakers is important for optimum sound quality in your room.

Speaker placement plays an important role
in the reproduction of sound using Sur-
round. The manner in which the speakers
are placed varies depending on the size of
the room and the wall coverings used in the
room. The following shows an example of
a layout for standard speaker placement.
Refer to the example for placing the speak-
ers appropriately in order to experience the
best Surround sound.
In principle, for Surround sound reproduc-
tion, two Front speakers and two Surround
(Rear) speakers are required. Refer to the
illustration on the left.
If the Front left and mght speakers are
placed too far away from each other, sound
spreads out too much and is dispersed
resulting in diminished sound quality.
To enjoy Surround sound, a Center speaker
is required in addition to the four basic
speakers.
If a screen with a projector is used, place
the Center speaker under the screen. If a
Monitor TV 1s used, it is recommended that
the Center speaker be placed on top of or
under the Monitor.
To bring out the feeling of shifting sound,
the rear speakers should not be placed on
the floor, but would be most effective
placed above ear position. They can also be
placed facing the ceiling or walls to reflect
the sound.
To enjoy powerful bass sounds, install a
subwoofer with a built-in power amplifier.
The placement of the Subwoofer does not
affect the final quality of the sound image
too much, therefore as its exact placement
is not critical, you can install it more with
the room layout in mind. To especially
enjoy A/V Surround, a Subwoofer can
bring out the best features of Dolby Pro
Logic Surround.
