Replacement Receiver: The SWT-2 is a replacement wireless
receiver for MartinLogain's SWT-2 wireless receiver/transmitter package
(839SW2TRD, sold separately).
Note: The SWT-2 can only be used as a replacement receiver for the
SWT-2 wireless receiver/transmitter package. You cannot connect two
receivers to one transmitter.
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 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: The wireless receiver is fitted with stereo RCA jacks. The receiver plugs into the sub or LFE input on
your powered subwoofer via stereo RCA (cable not included).
AC Power Adapter: The SWT-2 receiver includes an AC
power adapter which will need to be plugged into an AC wall outlet.
- Input: 100-240V ~ 60/50Hz,
