Hookup Information
Your MR26S speakers were designed to
work with your JBL Mini System. The Mini
System has speaker output connections
for hooking up just one pair of loudspeak-
ers. Do not attempt to hook up any extra
speakers through the same connections
as your MR26S speakers. Using more
than just the two MR26S speakers could
lead to a low impedance load causing
damage to the amplifier.
POWER HANDLING
Thanks to their high efficiency, the JBL
MR26S Loudspeakers will produce rea-
sonable volume levels in a room of mod-
erate size with very little amplifier power.
However, using a small amplifier to obtain
the desired volume listening levels may
lead to overdriving the amplifier. This will
generate high distortion levels and may
cause damage to your loudspeaker. For
the best performance, an amplifier should
be selected with an output rating that is
greater than the maximum power that will
be used. This margin of reserve power will
ensure that the amplifier will not attempt to
deliver more power than its design allows.
However, the amplifier’s power rating per
channel must not exceed the maximum
recommended amplifier power for that
specific loudspeaker model. Please see
the specification section for details.
Following these guidelines will provide vir-
tually distortion-free sound reproduction
and long loudspeaker life.
TROUBLESHOOTING
The vast majority of new speaker “mal-
functions” end up being traced to connec-
tions or switch settings. To avoid packing
up correctly functioning speakers and
sending them off, only to find that they’re
not really at fault, check the following tips
first, before requesting service.
No sound at all or very faint sound
from both speakers
1
. Amp/receiver tape monitor button pushed
in while using CD, FM or phono inputs.
2.
Wrong speaker switch, “A” or “B”
speaker output.
3
. Sound source (CD, cassette deck,
turntable) not turned on, not activated, 
not hooked up or not selected on
amp/receiver front panel.
No sound from one speaker
1. 
Balance control turned all the way left
or right.
2.
Speaker wire has become disconnected.
3
. One of the connections between sound
source and amp/receiver is faulty or has
become disconnected.
Both speakers play at low volumes 
but shut off as volume is increased OR
sound turns on and off intermittently. 
A few strands of speaker wire may be
shorting out. Recheck the connections.
Bass is very weak AND/OR sound
seems to come from each speaker sep-
arately, without creating a stable stereo
image between the speakers.
1.
The polarity (+ & –) of one speaker has
been reversed relative to the other.
Double check connections.
2. 
Speakers are too far away from back
and side walls or too far apart. Experiment
again with the speaker placement. If you
are still encountering problems, consult
your JBL dealer.
GENERAL CARE
The grille is held in place by pins near the
edges. To remove the grille, grasp it by
both top and bottom edges and pull gen-
tly. To replace grille, re-position it carefully
and press gently at the corners. Do not
push on the center area of the grille. 
The loudspeaker cabinet may be cleaned
with a slightly damp cloth. To remove dust
from the grille cloth, use a vacuum with a
brush attachment. Spots may be removed
with a commercial spot remover. Do not
use any cleaners or solvents on the
speaker drivers themselves.
SERVICE
Should your loudspeaker ever need serv-
ice, return it to the JBL dealer from whom
