Harman Kardon AVR20 II

Surround Sound
The AVR20 I! is equipped with 3 types
of surround processors (DOLBY
PRO-LOGIC, DOLBY 3 STEREO and
HALL) which provide a sense of
presence and expansion and let you
enjoy surround-sound in your home.
Every day, we are exposed to sounds
coming from our surroundings. Some
sounds reach our ears directly from the
source, some indirectly reflected by
walls or ceilings. Sounds of voices
reach us from behind, sounds of cars
reach us from the side. Sounds
coming from all around us are called
“surround-sounds’.
In order to recreate with as much
precision as possible that special
sound in movie theaters, speakers are
placed both in front of and behind the
listeners. One reason that sound from
the television in our homes is so
different from sound in movie theaters
is because usually sound from a
television only comes from in front of
the viewer. With a surround system,
the sounds of applause and cheers
from the stands during a baseball
game on TV come from in front and in
back, from the left and right.
The sound from a TV equipped with a
single speaker (or 2 speakers with
stereo televisions) sounds very
different from the actual, “live” sound.

Surround Processors
- HALL
Hall mode works best for recorded
concerts and other music programs. In
this mode, the front speakers provide a
normal stereo effect while the rear
speakers provide a reverberated sound.
This reverberation helps simulate the
sound you might hear at a live concert.
- DOLBY 3 STEREO
Combining the front and rear signals
so that you can enjoy a regenerated
sound field which has comparatively
more presence and a more expansive
feeling from the front 3 channels (front
L, front R, center speakers) than that -
of ordinary stereo regeneration.
- DOLBY PRO-LOGIC SURROUND
A great number of movies made in.
recent times have the sound track
specially encoded with the Dolby
Surround mode (carrying the (dolby
stereo) or (dolby surround)
trademark*). The front speakers
provide the dialogue and the normal
stereo effect, while the rear speakers
reproduce the surround signals. This
position provides excellent results when
watching television programs, video
software, video discs or video tapes of
stereo television broadcasts encoded
with Dolby Surround. Dolby Stereo films
have dramatically changed the role of
the movie-goer from that of observer to
that of participant. Clearer dialogue,
richer music, enveloping ambience,
on-screen, and making high-fidelity

parts of cinematic presentations. Imagine
recreating the same sort of audio-visual
experience right in your own home.

Select this mode if you use a small center speaker. The bass
sound of the center channel is output from the front speakers,
as a small speaker can’t produce enough bass.
