MartinLogan SWT-1 Subwoofer Wireless Transmitter for Dynamo 700 and Dynamo 1000 (Single, Black)Subwoofer wireless transmitter designed specifically for use with the MartinLogan Dynamo 700 and Dynamo 1000 subwoofers. 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 ML SWT-1 operates in the 2.4 GHz 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.
