Make your sub go wireless
Want to enjoy the deep, rumbling bass of your subwoofer without a long cable run from your receiver? Pick up the MartinLogan SW2-TRD wireless transmitter and receiver, and transform your wired sub into a wireless unit. Simply connect the transmitter to your receiver's subwoofer preamp output. Then connect the receiver to the LFE input on your subwoofer. With a wireless range of up to 40 feet, you'll have more placement options to help you enjoy powerful bass to add depth to movies and music.
The SW2-TRD transmitter and receiver each include an AC adapter for power. Be sure to plug them into a quality power protection device to protect your equipment from damaging surges.

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 original signal.
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.
