Additional Information
Memory page
Internal memory to store preset radio
stations. This receiver provides 3 "pages" (A,
B, and C). Each memory page lets you store
10 FM or AM stations; therefore, you can
store a total of 30 stations.
Parameter
Variable of sound that composes sound
image, such as tone or delay time. You can
customize the pre-programmed sound fields
by adjusting parameters to suit your listening
situation.
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.
Programmable remote
Remote control with "learning" capability.
You can control not only Sony components
but non-Sony components by programming
the control signals of these components.
Sound field
Sound pattern produced by a sounding
source or sources in a given environment due
to direct and reflected sounds and the
acoustics of the environment. The receiver
offers pre-programmed sound fields like,
DOLBY SUR, THEATER, and HALL (etc.) to
let you enjoy surround sound easily.
Station index
Index name given to preset radio stations.
You can group preset stations by assigning
the same station index to them.
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.
