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. 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.
