Wireless Sub Receiver/Transmitter Combo Pack: Although correct
placement plays a key role in optimizing subwoofer performance, sometimes it
imposes the inconvenience of running long lengths of cable through walls, along
baseboards, or under floors and carpets. To solve the problem, MartinLogan
designed the SWT-2 Receiver/Transmitter Combo Pack which allows you to place
your subwoofer in the exact location where it will deliver the best bass without
the cable clutter.
Compatibility: The MartinLogan SWT-2 wireless receiver/transmitter
combo can be added to any AV receiver with an LFE/RCA output and any powered
subwoofer with LFE/RCA input.
Uncompressed Audio Signal: MartinLogan engineers designed the SWT-2
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 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
2.4GHz Frequency Range: The SWT-2 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.
40' Range: In a typical room situation, the SWT-2 receiver/transmitter
combo has a maximum unobstructed operating range of 40' (12.5m) depending on
placement of course. If desired, its compact dimensions allow it to fit neatly
into an audio/video rack.
RCA Connectors: Both the wireless transmitter and wireless receiver
are fitted with stereo RCA jacks. The wireless transmitter plugs into the sub or
LFE output of your home receiver or active soundbar speaker via stereo RCA
(cable not included). The wireless receiver plugs into the sub or LFE input on
your powered subwoofer via stereo RCA (cable not included).
AC Power Adapters: The SWT-2's receiver and transmitter include an AC
power adapter which will need to be plugged into an AC wall outlet.
