Frequently Asked Questions - LB6-SW100 BOSCH

How do I connect the LB6-SW100 subwoofer to my receiver?

Use an RCA cable from the subwoofer output on your receiver to the line-level input on the subwoofer. Alternatively, use speaker-level inputs if your receiver lacks a dedicated sub output. Ensure the subwoofer is powered on and the volume is set low initially.

What is the best placement for the subwoofer?

Place the subwoofer in a corner or along a wall for enhanced bass. Avoid placing it directly against furniture or in the center of the room. Experiment with position to minimize boominess and achieve balanced sound.

My subwoofer has no sound. What could be wrong?

Check that the subwoofer is powered on and the power cable is connected. Verify the audio source is sending a signal and the volume is turned up. Ensure the crossover frequency is set correctly and the phase switch is in the proper position. Also, check that the mute feature is not enabled.

How do I set the crossover frequency?

Set the crossover frequency to match your main speakers' low-frequency limit. Typically, for bookshelf speakers, set around 80 Hz; for floorstanding, around 60 Hz. Adjust to your preference to blend smoothly with the main speakers.

What does the phase switch do?

The phase switch (0 or 180 degrees) adjusts the subwoofer's timing relative to the main speakers. Use the setting that gives the most bass output at your listening position. Sit in the main listening area and toggle the switch to hear which produces stronger, tighter bass.

Can I use the subwoofer for home theater?

Yes, the LB6-SW100 is designed for both music and home theater. It adds depth to movie soundtracks and reproduces low-frequency effects. Connect it to your AV receiver's subwoofer output for optimal performance.

How do I clean the subwoofer?

Unplug the subwoofer and wipe the exterior with a soft, dry cloth. Do not use any liquids or cleaning agents. Ensure the ventilation grille is free of dust to prevent overheating.

The subwoofer makes a humming noise. What should I do?

Humming can be caused by a ground loop. Try connecting the subwoofer to the same power strip as your other audio equipment. If the hum persists, use a ground loop isolator on the RCA cable. Also, check that all cables are securely connected.

What is the power consumption in standby mode?

The standby power consumption is less than 0.5 Watts, making it energy efficient. The subwoofer automatically enters standby after a period of inactivity.

How do I reset the subwoofer to factory settings?

There is no specific reset button. To reset, turn off the subwoofer, unplug it for 30 seconds, then plug it back in. This will clear any temporary settings. For full reset, refer to the user manual or contact Bosch support.

1 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).

5 Wiring

5.1 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.

Figure 5.1: Wattage tap

5.2

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.

5.3

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.

6 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.
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.
