Preset station

A radio broadcasting station that is stored in
memory of the receiver. Once you “preset”
stations, you no longer have to tune in the
stations. Each preset station is assigned its
own preset number, which lets you tune
them in quickly.

Surround sound

Sound that consists of three elements: direct
sound, early reflected sound (early
reflections) and reverberative sound
(reverberation). The acoustics where you hear
the sound affect the way these three sound
elements are heard. These sound elements are
combined in such a way that you can actually
feel the size and the type of a concert hall.

• Types of sound

• Transition of sound from rear speakers

Test tone

Signal given out by the receiver for adjusting
the speaker volume. The test tone will come
out as follows:

• In a system with a centre speaker

(NORMAL/WIDE/3 CH LOGIC modes)

The test tone is output from the front L
(left), centre, front R (right), and rear
speakers in succession.

• In a system without a centre speaker

(PHANTOM mode)

The test tone is output from the front and
the rear speakers alternately.
Glossary

Centre mode

Setting of speakers to enhance Dolby Pro
Logic Surround mode. To obtain the best
possible surround sound, select one of the
following four centre modes according to
your speaker system.

• NORMAL mode

Select NORMAL mode if you have front
and rear speakers and a small centre
speaker. Since a small speaker cannot
produce enough bass, the bass sound of
the centre channel is output from the front
speakers.

• WIDE mode

Select WIDE mode if you have front and
rear speakers and a large centre speaker.
With the WIDE mode, you can take full
advantage of Dolby Surround sound.

• PHANTOM mode

Select PHANTOM mode if you have front
and rear speakers but no centre speaker.
The sound of the centre channel is output
from the front speakers.

• 3 CH LOGIC mode

Select 3 CH LOGIC mode if you have front
and centre speakers but no rear speaker.
The sound of the rear channel is output
from the front speakers to let you
experience some of the surround sound
without using rear speakers.

Delay time

Time lag between the surround sound output
from front speakers and rear speakers. By
adjusting the delay time of the rear speakers,
you can obtain the feeling of presence. Make
the delay time longer when you have placed
the rear speakers in a small room or close to
your listening position, and make it shorter
when you have placed them in a large room
or apart from your listening position.

Direct tuning

Tuning method to let you directly enter a
station’s frequency using the numeric
buttons. Use this method if you know the
frequency of the station you want.

Dolby Pro Logic Surround

Decoding system of Dolby Surround sound
standardized in TV programmes and movies.
Compared with the former Dolby Surround
system, Dolby Pro Logic Surround improves
sound image by using four separate channels:
off-screen audio effects, on-screen dialog,
left-to-right panning, and music. These
channels manipulate the sound to be heard
and enhance the action as it happens on the
screen. To take advantage of Dolby Pro Logic,
you should have at least one pair of rear
speakers and/or one centre speaker. You also
need to select the appropriate centre mode to
enjoy a full effect.

Dolby Surround

Encoding and decoding system of Dolby
Surround sound for consumer use. Dolby
Surround decodes the extra channels on the
Dolby Surround-encoded sound tracks of
movie videos and TV programmes and
produces sound effects and echoes that make
the action seem to envelop you.
The receiver offers Dolby Surround as one of
the pre-programmed sound fields. If you
have rear or centre speaker(s), we
recommend that you customize the Dolby
Surround sound field by selecting the
appropriate centre mode to take advantage of
Dolby Pro Logic Surround sound.
