Reverberation Time (REVERB)
This parameter adjusts the length of time required for
the reverberation (echoes) generated from a given
sound to attenuate –60 dB.
You can choose shorter (S) or longer (L) reverberation
times.
Note
The EFFECT parameter allows you to adjust the overall
presence of the sound field.
Customizing the Sound Fields
Each sound field is composed of an equalizer
(STR-GA8ES) or tone controls (STR-GA7ES) and
surround sound parameters — variables of sound, that
create the sound image. You can customize the sound
fields by adjusting some of the sound parameters to
suit your listening situation. See the charts on page 22
for the parameters available in each sound field.
Once you customize the sound fields, they are stored in
memory unless the receiver is unplugged for about 1
week.
