Safety
!
Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Bosch strongly recommends all loudspeakers be suspended taking into account all
current national, federal, state, and local laws and regulations. It is the responsibility of the
installer to ensure all loudspeakers are safely installed in accordance with all such
requirements. When loudspeakers are suspended, Bosch strongly recommends the system be
inspected at least once per year or as laws and regulations require. If any sign of weakness or
damage is detected, remedial action should be taken immediately. The user is responsible for
making sure the wall, ceiling, or structure is capable of supporting all objects suspended
overhead. Any hardware used to suspend a loudspeaker not associated with Bosch is the
responsibility of others.
Safety Agency Compliance
The LB6-S and LB6-SW100 bracket systems have successfully passed EIA-636 at a safety
factor of 8:1. The bracket systems are intended to support only the LB6-S and LB6-SW100
respectively. Do not use either bracket system for any other purpose. Never set anything on or
hang anything from the LB6-S or LB6-SW100 enclosures when using the brackets.
As an added safety measure, it is suggested the user install an extra suspension point back to
the building structural supports. This redundant safety point should have as little slack as
possible (less than one (1) inch is preferable).

Welcome
Thank you for purchasing the LB6 Compact Sound Speaker System. Read through this manual
to familiarize yourself with the features, applications, and precautions before you use these
products.
The LB6 Compact Sound Speaker System is a very compact full-range loudspeaker ideal for
applications requiring high-quality sound. Its shape flexibility and size make it nearly invisible
for use in background/foreground music systems for restaurants, bars, patios, retail, and other
applications. The system consists of a high performance surface mount 8-inch subwoofer
module with a crossover network to support the included four (4) surface mount 2-inch
satellite speakers. The system provides for easy signal connections at the subwoofer and can
support either 4/8 ohm or 70/100v signal connections. Its high power handling allows the
system to be used in a wide variety of environments and spaces to provide high quality
background or foreground music.

only industry-accepted fasteners and mounting methods when mounting the wall bracket.
Consult an expert if you are unsure.
To install the surface mount satellite speaker, do the following:
1. Using a Phillips head screwdriver (not supplied), tighten two (2) M5 pan-head screws
(not supplied) to attach the wall bracket to a secure mounting surface.
2. Using a Philips screwdriver, tighten two (2) M5 pan-head screws (supplied) to attach the
speaker bracket to the rear of the cabinet.
3. Place the speaker bracket onto the wall bracket.
4. Using the hex wrench (supplied), tighten the M6 hex drive pan-head screw to secure the
speaker bracket to the wall bracket.

Wiring
Wattage tap
Prior to wiring your system, select the mode of operation (100V/70V/4 ohm or 8 ohm stereo)
by setting the slider switch to the appropriate setting. Select taps using the rotary switch on
the subwoofer input panel. The power taps are 100 W, 50 W, 25 W, and 12.5 W at 70.7V and
100V, as well as a 4 ohm transformer bypass setting. A guide on the input panel shows which
switch positions to use for the power settings at 70V and 100V.

70v/100v/4 ohm Mono
The amplifier and LB6 Compact Sound Speaker System is wired for MONO mode. It is highly
advisable to support the unit while these connections are being made. Connect all wires to
the speaker at the back terminal plate observing proper polarity of the connections. After all
connections are made test the complete system operation.
Notice!
Any combination of four satellites (surface mount, ceiling or pendant speakers) is allowed.
The system is designed for operation with only four (4) satellite speakers. Operation with less
than four (4) satellite speakers is not recommended.

8 ohm Stereo
The amplifier and LB6 Compact Sound Speaker System is wired for STEREO mode. It is highly
advisable to support the unit while these connections are being made. Connect all wires to
the speaker at the back terminal plate observing proper polarity of the connections After all
connections are made test the complete system operation.
Notice!
The system is designed for operation with four (4) satellite speakers. Operation with less
than four (4) satellite speakers is not recommended.
Notice!
A standard low impedance (4/8 ohm) amplifier source is required when operating the unit in
STEREO mode.
100/70v operation is not supported in STEREO mode.

Troubleshooting
Problem Possible Causes Action
No Sound Amplifier Connect a known working test speaker to the amplifier outputs. If
there is no sound, check all electronics are on, the signal routing is
correct, the source is active; the volume is turned up, and so on.
Correct/Repair/Replace as necessary. If there is sound, the problem is
in the wiring.
Wiring Verify you have connected the correct wire pairs to the amplifier. Play
something at low level through the amplifier (for example, from a CD
player or tuner). Connect the test speaker in parallel with the
malfunctioning line. If the sound has gone or is very weak, the line has
a short in it (possibly a severe scrape, pinch, or staple puncture). If
the sound level is normal the wire is open (possibly a cut wire or
missed connection). Using the test speaker, move down the line and
test each connection/junction until you find the problem and correct
it. Observe proper polarity.
Verify you have the inputs and outputs connected to the correct wires.
If the subwoofer input panel is not correctly wired, there will be little
or no sound. Observe proper polarity.
Poor Low-
Frequency
Response
Speakers Wired Out-
of-Polarity
When two (2) speakers are connected out of polarity (out of phase),
the low frequencies will cancel each other acoustically. Carefully
observe the wire markings or tracers on your speaker wires. Verify the
amplifier (+) terminal is connected to the red speaker terminals and
the amplifier (-) terminal is connected to the black speaker terminals.
Improperly Wired
Subwoofer Panel
Using a test speaker as described above, verify all amplifier and
speaker wires are connected to their proper terminals with the correct
polarity. Reversing just one (1) set of amplifier wires can cut out all
bass output from the subwoofer.
Intermittent
Output such as,
Crackling or
Distortion
Faulty Connection Check all connections at amplifier and speakers to ensure they are
clean and tight. If the problem persists, it may be in the amplifier or
wiring. See other actions above.
Constant Noise
such as Buzzing,
Hissing, Humming
Defective Amplifier
or other Electronic
Device
If the noise is present but no program material is playing, the likely
cause is the signal chain in the electronics. Evaluate each component
as necessary to isolate the problem.
Poor System
Grounding or
Ground Loop
Check and correct the system grounding, as required.
If these suggestions do not solve your problem, contact your nearest Bosch dealer or Bosch
distributor.
