■Do not place furniture or other
heavy objects on the cord, and
avoid dropping heavy objects on
it. Also do not make a knot in the
cord.
Place the unit on a firm
and level surface.
Avoid installing it:
■In moist or humid places;
■Close to heating equipment or in
places exposed to direct sunlight;
■In a direct draft from an air
conditioner or in other very cold
locations;
■In places subject to excessive
vibration or dust;
■In poorly ventilated places.
Moving the Unit.
Before moving the unit, be sure to
unplug the power cord from the AC
outlet and disconnect all wires to
antennas and other components.
Do Not Open the Cabinet.

objects enter the unit, unplug the
power cord immediately and consult
an authorized JBL service center.
Using the unit under such conditions
may cause a fire or shock hazard.
Cleaning.
Remove dust by wiping the unit with a
soft, dry cloth. If necessary, use a soft

1. FM INDOOR ANTENNA
Connect the supplied antenna (the
wire lead) to a 300Ω/75Ωadapter
and connect the adapter to the 75Ω
T-shaped FM antenna terminal, as
shown in the Rear Panel Connection
Diagram. Change the position of the
antenna until you get the best recep-
tion of your favorite stations.
2. FM OUTDOOR
ANTENNA
An outdoor FM antenna may be used
to further improve the quality of
reception. Disconnect the indoor
antenna before replacing it with the
outdoor one. A 75Ω/300Ωadapter
must be used.
3. AM LOOP ANTENNA
Tune in your favorite AM station and
position the loop antenna for best
reception. Try other stations and find
the position that gives the best overall
reception. When this unit is mounted
in a rack or placed on a shelf with
insufficient space behind, hang the
antenna on a wall in the direction
which gives the best reception.
NOTE: If noise is heard during AM
reception, move the antenna for bet-
ter reception. To prevent undesired
noise, the AM LOOP ANTENNA
should be located at least 30cm
away from the remote control wiring.
4. SYSTEM GROUND
TERMINAL
To reduce hum to a minimum, con-
nect the ground lead from your
turntable to this terminal.
5. PHONO INPUT JACKS
Input for TURNTABLE with an MM
cartridge having 47K ohms of load
impedance. Connect shielded cables
from your phono to the LEFT and
RIGHT input jacks.
NOTE: Do not place your
TURNTABLE on a speaker enclosure.
This will avoid howling caused by
transmission of the speaker vibration
to the TURNTABLE.
6. TV/AUX INPUT JACKS
This extra stereo input is provided for
any source you want to hear. An
additional compact disc player, a
tape recorder, a video cassette

CASSETTE DECK to these jacks. This
input may be connected to the line
output of the audio processor like an
optional graphic equalizer or a Digital
Signal Processor.
11. TAPE 2 MONITOR REC
JACKS
Connect the line input of your
CASSETTE DECK to these jacks. EQ
controls, loudness and volume set-
tings have no effect on the signal
from this output for recording. To
monitor this input source while
recording, press the TAPE 2 MONI-
TOR button (MONITOR ON position).
These REC jacks may be used for the
line input of the audio processor like
an optional graphic equalizer or a
Digital Signal Processor.

Surround Sound
The JSR655 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 com-
ing 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 left
and right.
The sound from a TV equipped with
a single speaker (or 2 speakers with
stereo televisions) sounds very differ-
ent 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 pro-
vide a normal stereo effect while the
rear speakers provide a reverberated
sound. This reverberation helps simu-
late 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 soundtrack
specially encoded with the Dolby
Surround mode (carrying the Dolby
Stereo or Dolby Surround trademark).
The front speakers provide the dia-
logue and the normal stereo effect,
while the rear speakers reproduce the
surround signals. This position pro-
vides excellent results when watching
television programs, video software,
video discs or videotapes of stereo
television broadcasts encoded with
Dolby Surround. Dolby Stereo films
have dramatically changed the role of
the moviegoer from that of observer to
that of participant. Clearer dialogue,
richer music, enveloping ambience
on-screen, and making high-fidelity
multidimensional sound are essential
parts of cinematic presentations.
Imagine recreating the same sort of
audio-visual experience right in your
own home.

Speaker Installation
The JSR655 incorporates a decoder
which reproduces the specially
encoded surround-sound of Dolby
Surround video programs. In Dolby
Surround mode, select the speaker
operation mode according to your
speaker system.
NORMAL mode
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.
