The ARW20 from Acoustic Research is a simple and convenient modular wireless adapter system that allows you to turn the rear speakers in your home theater surround sound system into wireless speakers, eliminating the need to run wires across the room. The system consists of a wireless transmitter and a pair of amplified receivers.
The transmitter connects to your home theater and uses 2.4GHz technology to send uncompressed CD-quality audio to the receivers. The transmitter is capable of supporting up to 5 speaker receivers and a subwoofer, allowing you to add additional components later on for a fully-wireless home theater solution.
Each receiver has an integrated 60W amplifier for powering a speaker. Standard 5-way binding post outputs let you connect the receivers to practically any home theater speakers. If desired, both receivers can be tuned to the same transmitter channel, making the system ideal for multi-room music use in addition to its surround sound applications.
