Features

Wireless Subwoofer System (SWT-X): 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, certain Dynamo series powered subwoofers from MartinLogan include a USB-A connection port for their new SWT-X Wireless Subwoofer System, consisting of a wireless transmitter (SWT-TX) and receiver (SWT-RX). MartinLogan's SWT-X incorporates the latest in wireless audio transmission technology - including 2.4GHz dynamic frequency selection, forward error correction, and a range of up to 50'. 

Notes:
  • The included wireless transmitter (SWT-TX) and receiver (SWT-RX) come already paired.
  • MartinLogan's previous SWT-2 wireless system is not compatible with the new SWT-X wireless system, and vise-versa. 

Compatibility: The SWT-X wireless subwoofer kit is compatible with select MartinLogan Dynamos series powered subwoofers - including the 600X, 800X, 1100X, and 1600X (all sold separately). Its also compatible with any AV receiver or integrated amplifier which features a stereo output, subwoofer output, or LFE output consisting of RCA jacks (cables sold separately). The SWT-X wireless system can be used to establish either a left/right stereo line-level connection or a LFE line-level connection.

Wireless Transmitter (SWT-TX): The SWT-X transmitter features stereo line-level RCA jacks which will need to be connected to your AV receiver's stereo, subwoofer, or LFE output. The transmitter's right line-level RCA input doubles as an LFE input for AV receivers with an LFE output in home theater applications (make sure to set your compatible Dynamo series powered sub's crossover to "Bypass" when utilizing the LFE). The included external AC power adapter will need to be plugged into the transmitter and an AC wall outlet or surge protector (sold separately).

Note: The transmitter measures 3.5" (w) x 1.125" (h) x 4.6875" (d).

Wireless Receiver (SWT-RX): Easy to install, the SWT-RX receiver requires no external power source or audio cables at the powered subwoofer. It simply plugs into the USB-A port of the compatible Dynamo series powered subwoofer. The receiver wirelessly receives a stereo or LFE audio signal from the transmitter connector to your AV receiver or integrated amplifier.

Note: The wireless receiver measures 2.1875" (w) x 0.8125" (h) x 3.375" (d).

Auto Power On/Off: The SWT-X wireless system shuts down to save power after about 20 minutes of no audio signal, and will automatically turn on when it senses an audio signal.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
I bought the Dynamo 800x but i did not get the wireless optional equipment, so i need it. [ Krishna  Oct 18, 2018 ]

1 question already asked

Q
1) is there any value of delay when you use this wireless device? (if I have another sub working with cable, should I notice any delay?) 2) is there any value that shows me that the bandwidth used in 2.4 GHz by this device, is enough to transmit the frequencies range just as a cable?
[ Ricky  Feb 04, 2019 ]
1 answer
A
The delay (if any) is usually imperceivable when using this transmitter. Bass frequencies don't hit your ears as sharply or directionally as mids and highs. That being said if you have one wired and one wireless subwoofer the delay might be more pronounced. I don't have any exact frequency within the 2.4GHz band the transmitter and receiver use. They are paired together to maximize connectivity and efficiently though. They work well.
