Go Wireless with Your MartinLogan Sub
Although correct room placement plays a key role in optimizing subwoofer performance, it can impose the inconvenience (not to mention unsightliness!) of running long lengths of cable through walls, along baseboards or under floors and carpets.
The MartinLogan SWT-1 Subwoofer Wireless Transmitter solves the problem. It allows you to place your Dynamo 700 or Dynamo 1000 subwoofers subwoofer in the exact location where it will deliver the best bass. Cable clutter becomes a thing of the past and actual system setup time can be dramatically reduced. Need to system troubleshoot at a later time? When you go wireless, there will never be an untidy mess of wires to sift through in order to find the right cable.
Solving the Placement Puzzle
While it's true that bass waves are non-directional and, in theory, you should be able to place your subwoofer anywhere in the room without affecting bass performance or the performance of your other speakers, it's never quite that simple. Bass is dramatically affected by the room itself. Dimensions, dead spots, archways, even furniture placement can cause bass to sound bloated or boomy with a lack of definition.
Achieving optimal bass almost always requires experimenting, with the sub in various parts of the room. Ah and there's the rub! While experimenting, you may discover the best place for the subwoofer is all the way across the room, far from the amplifier or receiver. Or maybe a "hidden" install is required. Both situations impose the inconvenience (not to mention unsightliness!) of running a long length of cable through walls, along baseboards or under floors and carpets. That's where the MartinLogan SWT-1 Subwoofer Wireless Transmitter comes in.
MartinLogan Dynamo 700 and Dynamo 1000 subwoofers are designed for wired or wireless operation. A wireless receiver built into each of these subs can be used to establish connection with the SWT-1. The 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.
The SWT-1 couldn't be easier to use. Just plug it into the wall, and connect your audio to the left and right / LFE RCA inputs. Press the sync button on the bottom of the transmitter, and you're done. You're ready for stunning bass performance, wirelessly.
Skeptical About Wireless Audio? Relax!
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 MartinLogan 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 (such as 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 our use of Adaptive FHSS operation. Think Bluetooth technology; it's similar.
In a typical room situation, the SWT-1's RF transmitter has a maximum unobstructed operating range of 40 feet (12.5 meters) depending on placement of course, and if desired, its compact dimensions allow it to fit neatly into an A/V rack. |
