The MRF-100B PowerBlaster base station is specifically designed to increase the range of Universal's RF10 and RF20 remotes. It receives the radio frequency (RF) commands these remotes transmit and converts them into infrared (IR) signals that can control your components. That allows you to operate your audio/video system from a range of 50 to 100 feet away, inside or out.
The base station sends commands out to your components via a built-in IR "blaster," or emitter. For gear that's not line-of-sight with the PowerBlaster, you can use the included mini emitters. Each of these small IR blasters comes with a self-adhesive pad and a 10-foot connecting cable, so they can be positioned just about anywhere, like behind a cabinet door.Turn on your stereo when you're out on your patio, and adjust the volume of your outdoor speakers in the process the RF signal penetrates walls, floors, and doors. With the PowerBlaster, your Universal remote becomes a whole-house solution for controlling your entertainment system.
