The Atlantic Technology WA-5030-r receiver/amplifier is a small device that receives the wireless signal from the matching WA-50-t transmitter and then drives a pair of 8-ohm speakers. It comes with its own remote control so that on-off and volume functions can be performed in the remote location, independent of the main system. Best of all, with the WA-5030, the sound is CD-quality, with no interference or delay and easy plug-and play functionality-no software needed.
