SWAT-2.4X consists of a transmitter (a unit connecting to the source) and a receiver (connecting to the amplifier or powered speaker). The SWAT-2.4X transmitter connects to a stereo, MP3 player, computer, or any other device that can play audio through a 3.5mm stereo jack or RCA output. It can also be connected directly to the speaker outputs via its high/speaker level input supporting 0.5–17V RMS. An RCA input connects the receiver to an amplifier or a powered speaker. Multiple receivers can connect wirelessly to one transmitter if you want the music to play in different areas or multiple systems. Extra receivers can also be purchased separately.

Once the transmitter and receiver are paired, the receiver will receive signals from the transmitter automatically. If there is any interference on the current channel, you must change the transmitter’s channel; the receiver can sense the frequency change and adjust automatically. It has 20 channels, more channels than any other wireless transceiver. There is also a one in 20 million chance that the pairing channel will interfere with a different signal. Both the transmitter and the receiver must be connected to a power source, of which there are two options. One is the DC power supply, which connects to any wall outlet, and the other is USB.
