Subwoofer Wireless Transmitter
Although correct room placement plays a key role in optimizing
subwoofer performance, it can impose the inconvenience (not to mention
unsightliness!) of running long lengths of cable through walls, along
baseboards or under floors and carpets. The SWT-1 Subwoofer Wireless
Transmitter solves the problem and allows you to place your subwoofer
in the exact location where it will deliver the best bass. Cable
clutter becomes a thing of the past and actual system setup time can be
dramatically reduced.Wireless Connection Simplifies Subwoofer Setup
While it's true that bass waves are non-directional and in theory,
you should be able to place your subwoofer anywhere in the room without
affecting bass performance or the performance of your other speakers,
it's never quite that simple. Bass is dramatically affected by the room
itself – dimensions, dead spots, archways, even furniture placement can
cause it to sound bloated or boomy with a lack of definition. Achieving
optimal bass almost always requires experimenting with the sub in
various parts of the room...and there's the rub! While experimenting,
you may discover the best place for the subwoofer is all the way across
the room, far from the amplifier or receiver. Or maybe a "hidden"
install is required. Both situations impose the inconvenience (not to
mention unsightliness!) of running a long length of cable through
walls, along baseboards or under floors and carpets. That's where the
MartinLogan SWT-1 Subwoofer Wireless Transmitter comes in...

MartinLogan Dynamo 700 and Dynamo 1000
subwoofers are designed for wired or "wire-less" operation. A wireless
receiver built into each of these subs can be used to establish
connection with the optional SWT-1 MartinLogan Subwoofer Wireless
Transmitter (sold separately and available from your authorized ML
dealer). The ML SWT-1 allows you to experiment with subwoofer placement
to your heart's content. Unsightly wiring becomes a thing of the past
and the actual reduction in system set-up time can be dramatic.


Under the Hood
Not convinced? Skeptical about wireless audio? You can relax!
Following extensive research and testing, MartinLogan engineers
designed the SWT-1 with an uncompressed 16-bit/48-kHz sampling rate
(exceeding the current CD standard of 16-bit/44.1-kHz), which proved
more than adequate (and accurate!) for use in the wireless transmission
of low-frequency information below 200 Hz. And since the RF
transmission is digital it is error-checked to ensure no deviation from
the original signal.
The SWT-1 operates in the 2.4GHz frequency range. Often, users of
wireless technology complain about interference from other noise
sources in the room (i.e. wireless local area networks, portable phones
on the same frequency, even microwave ovens). MartinLogan engineers
included an integrated RF power amplifier that provides a 15 dBm RF
power level to reduce interference. Stray RF interference is also
reduced through use of Adaptive FHSS operation (think Bluetooth
technology, it's similar!).
In a typical room situation, the SWT-1's transmitter has a maximum
unobstructed operating range of 40 feet (12.5 meters) depending on
placement of course. If desired, its compact dimensions allow it to fit
neatly into an audio/video rack.
