Frequently Asked Questions

Frequently Asked Questions & Troubleshooting 15

How do I clean my subwoofer?

Use a dust free cloth or a soft brush to clean your subwoofer.

We recommend a specialty cloth (available through the

Xtatic shop at www.martinlogan.com) that cleans better than

anything else we have tried.

Is it safe to set things on my subwoofer?

While your subwoofer is designed with a durable, stain-

resistant surface, we advise you not to set anything on your

subwoofer—especially containers holding liquids.

Is there likely to be any interaction between

my subwoofer and the 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 susceptible to magnetic fields..

Plamsma, LCD, and LED television are not suceptible to

magnetic interference.

Is there likely to be any interaction between

my subwoofer and other electrical devices in

my house?

yes. When operating wirelessly this subwoofer may be

susceptible to RF interference in the 2.4GHz bandwidth

from microwave ovens and wireless devices such as

WiFi systems, video game consoles, cordless telephones,

blue tooth devices, and baby monitors. Generally, this

issue (intermittent sound or slight popping noises) is eas-

ily resolved by physically separating problematic devices

from one another—a distance as little as two feet will

often alleviate the interference. In the case of microwave

ovens, the interference will only occur when the micro-

wave is operating.

Will my electric bill go 'sky high' by leaving my

subwoofer plugged in all the time?

No. When the power switch is set to ‘Auto On’ the

subwoofer will draw about 15 watts when idle and only

1 watts in standby mode.

Should I unplug my subwoofer during a thun-

derstorm?

Yes, or before. It's a good idea to disconnect all of your

audio/video components during stormy weather.

No Output

• Check that all your system components are turned on.

• Check that the master power switch adjacent to the AC

receptacle is set to 'Auto On'.

• Check your wires and connections.

• Check all interconnecting cables.

• Make sure the level control is not turned down.

• Turn off and unplug the subwoofer and check the fuse

near the AC power cord receptacle on the back. If the

fuse has blown, replace the bad fuse with a matching

fuse.

• 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.

• 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 operating in wireless mode, move the subwoofer

away from microwave ovens and/or any devices that

use wireless technology.

• If the problem persists, contact your dealer.

Intermitent Output With Wireless

• Make sure that no other wireless devices are within 2

feet of the SWT-2 transmitter.

• Check placement and make sure the SWT-2 wireless

transmitter is at least 1 foot off of the ground.

• Move the SWT-2 transmitter and sub closer together.

• Remove barriers from between the devices. Although

the SWT-2 uses an RF signal, it may not penetrate

some walls or cabinetry.
