Frequently Asked Questions

Why won’t my subwoofer read my USB flash drive when I attempt to add a custom low-pass filter or update my firmware?

When connecting a USB flash drive to the subwoofer’s USB Input, the drive must be formatted using a FAT32 file system. To learn more about formatting a flash drive using FAT32 please refer to your computer’s help documentation. Most flash drives (under 32GB) come pre-formatted as FAT32. Reformat your flash drive only if the upload doesn’t work.

How do I clean my subwoofer?

Use a dust free cloth or a soft brush to clean your subwoofer. We also recommend microfiber cloths.

Is it safe to set things on my subwoofer?

While your subwoofer is designed with a durable, stain-resistant surface, we advise you treat this like any piece of fine furniture and not to set anything on your subwoofer—especially containers holding liquids.

Is there likely to be any interaction between my subwoofer and the CRT television in my Audio/ Video system?

Yes. The subwoofer doesn’t use a shielded driver. We recommend 3 feet between the subwoofer and video components that are sus- ceptible to magnetic fields. Modern flat screen televisions are not affected by the magnets in your subwoofer.

Will my electric bill go 'sky high' by leaving my subwoofer plugged in all the time?

No. The subwoofer, when the power switch is set to ‘Auto’ or ‘Standby’, will draw about 30 watts when idle.

Should I unplug my sub during a thunderstorm? Yes, or before. It's a good idea to disconnect all of your audio/ video components during stormy weather.

I disposed of my speaker’s original packaging. Can I buy new packaging for my speaker?

Yes, replacement packing is usually available for current and recent MartinLogan products. However, replacement packaging may sometimes be quite expensive and we encourage listeners to save their original packaging materials. MartinLogan cartons will collapse and flatten for easy storage. Foam and additional packing materials may be safely stowed in a large plastic bag.

Troubleshooting

No Output

•Check that all your system components are turned on.

•Check that the power switch on the subwoofer is set to either 'Auto (Trigger)' or 'On'.

•Check your wires and connections.

•Check all interconnecting cables.

•Make sure the level control is not turned down.

•If the problem persists, contact your dealer.

Muddy Bass

•Check placement. Try moving the subwoofer closer to the front and side walls.

•Check the type of feet that are being used. Try installing the ETC spikes.

•Decrease the level.

•Check your processor setup.

•Check that the Low-Pass Filter frequency is no set too high.

•If the problem persists, contact your dealer.

Hums or Unusual Sounds

•Turn the subwoofer off, unplug all signal inputs, turn the subwoofer back on and turn up the level. If the problem disappears, the hum is originating elsewhere in your system.

•Connect the subwoofer’s AC connection to the same AC circuit as the pre amp.

•If the problem persists, contact your dealer.
