Our take on the Universal MRF-100B PowerBlaster by Crutchfield's Ralph Graves
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.
great addition to the RF 20 remote, works seamlessly.

Universal MRF-100B PowerBlaster Reviews
Average Customer Review(s):
Thanks for submitting your review
Overview: The PowerBlaster (MRF100B) RF receiver provides an affordable and innovative "whole-house" solution to home theater operation. After receiving RF signals from an RF10, RF20, or RF30 universal remote control, the MRF100B converts the signals to IR commands and sends the commands to out-of-sight components via built-in front blasters, indoors or outdoors, up to 100' without pointing.
Flashers: Self-adhesive flashers affix to the front panels of your components. The flashers relay commands to components out of sight of the MRF100B's front blaster. The flashers plug in to the MRF100B rear flasher line output jacks. Each flasher has a 9.75' cable to easily reach components on nearby shelves.
Mounting: Using the four enclosed screws, you can choose to fix the mounting plate to a wall or the back of your component cabinet.
Connections: The MRF100B has the following connections on its back panel:
- DC 9V: for use with the supplied AC adapter
- IR Outputs: six minijacks for use with supplied flashers
- Power Supply: 9V 300mA
- RF Frequency: 418 MHz
