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.
Suspension Cable Important Safety Instructions:
Load - Do not exceed the WLL (Working Load Limit) of the pendant suspension cable.
The WLL of the pendant suspension cable is 10 kg (22 lb).
No lifting - Do not use for lifting, such as in a crane or pulley situation.
No movement - The pendent suspension cable is to be used to suspend static loads only. Do
not use the cable to suspend moving objects or objects likely to be subject to
movement.
No joining - Do not splice together the pendent suspension cable with another cable or
other joining device. The pendent suspension cable as supplied is the maximum
length available and should not be altered in any way.
Not for re-use - Do not re-use the pendent suspension cable; it is designed for permanent fixed
installation use only.
Lubricants - Do not apply oil or any other lubricant to any part of the assembly.
Round duct/pipes - When wrapping around duct or other round pipes, do not exceed an angle of 60
degrees between the top of the pipe and the pendent suspension cable.
I-Beams - Minimum radius on I-Beams to be no less than 1/8-inch.
Corners/edges - Cables in contact with corners, edges, protrusions, or abrasive surfaces shall
be protected with a material of sufficient strength, thickness, and construction
to prevent damage.
Old electrical and electronic appliances
Electrical or electronic devices that are no longer serviceable must be collected separately and
sent for environmentally compatible recycling (in accordance with the European Waste
Electrical and Electronic Equipment Directive).
To dispose of old electrical or electronic devices, you should use the return and collection
systems put in place in the country concerned.

Introduction
The LP6-S-L Pendant Mount Satellite Speaker is a companion speaker option to the Compact
Sound Speaker System offering from Bosch . It provides a convenient way to equip open
ceiling spaces with sound where conventional surface or ceiling mount speakers cannot be
used. The 2-inch (50 mm) transducer provides matched performance to the other Compact
Sound Satellite speaker models. The unit comes complete with a UL rated mounting cable and
can be used in any combination with the Compact Sound ceiling or surface mount subwoofers
and satellite speaker models. It’s ideal for use in a wide variety of environments and spaces to
provide high quality background or foreground music.
Read through this manual to familiarize yourself with the safety information, features, and
applications before you use these products.

Pendant suspension cable
The pendant suspension cable is supplied with the LP6-S-L kit. The material is strong steel
wire rope. It is designed with a locking spring mechanism which secures the wire rope and
allows for easy adjustment of the installation height, up to 15 ft (4.57 m).
Working Load Limit
The pendant suspension cable’s WLL is based on the suspension being hung vertically. If the
cable is suspended at an angle, a second suspension cable is required.
!
Caution!
Do not hang the pendant suspension cable at an angle in excess of 60° from vertical.

Wiring
Wiring the pendant speaker is recommended before installation. 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.
To wire the pendant speaker, do the following:
1. Install the wire through the grommet in the wire cap.
2. On the phoenix connector, insert one (1) wire into the positive (+) port.
3. On the phoenix connector, insert one (1) wire into the negative (-) port.
4. Using a screw driver, tighten the two (2) screws to secure the wires.
5. Insert the phoenix connector into the connector socket in the speaker base.
6. Place the wire cap onto the speaker base.
Ensure the main suspension tab is aligned.
7. Tighten the three (3) screws on the wire cap.

Installation
Wiring the pendant is recommended before installation. For more information, see Wiring,
page 9.
To install the pendant speaker, do the following:
1. Thread the cable into the coupler.
2. Adjust the pendant suspension cable length.
3. Place the pendant suspension cable over the ceiling support.
4. Thread the cable into the opposite side of the coupler.

5. Once the proper height adjustment has been made, put the cable tail through the
through hole of the coupler, and leave at least 10 cm (4 in) of length.
6. Tighten the screw to secure the cable.
7. Support the speaker, snap the support hanger onto the main suspension tab (center)
located on the top of the speaker.
8. Attach a secondary auxiliary support cable onto one (1) of the secondary auxiliary
support holes.
9. Secure the secondary auxiliary support cable to a different ceiling support point of the
building structure.

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 dealer or distributor.
