MRF-300 BASE STATION
Features and Benefits
Interference Rejection and Adjustable RF Range via RFX-150
The MRF-300 receives RF (radio frequency) signals via the RFX-150 RF Sensor.
The RFX-150 displays RF interference via a bright RED LED, which flickers when
interference is present. Simply relocate the RFX-150 out of the interference or
reduce the range to eliminate interference via the RF Range adjust screw.
Expand Range by Adding RFX-150 RF Sensors in Remote Areas
The MRF-300 can power up to three RFX-150 RF Sensors connected in parallel
to the RF Input connector.
Variable IR Output Matches Rear Panel IR Inputs
The MRF-300 is equipped with adjustable IR line outputs, each output can be indi-
vidually matched to rear panel IR inputs on any component that is designed to be
operated by a standard IR repeater.The outputs utilize a 3.5mm jack.
Up To Fifteen Equipment Locations With Identical Components
Each URC MX series “addressable” remote control can be programmed to
specifically control components in a particular room, by installing a base station at
each location. In operation it’s simple: when you select a device located in the
Den, the MX series remote only sends commands to the Den. When you select
a device located in the Family Room, the MX-3000 only sends commands to it.
A Single MRF-300 Can Control an Array of Identical Components
or Identical Zones of a Multi Zone Preamp/Matrix Switcher
Each MRF-300 has six “addressable” IR Line Outputs. For example, you can con-
trol up to six identical TV’s with one MRF-300 or route volume commands for a
specific zone to a particular zone IR input on a multi-zone preamp. If you have
more than six identical components or zones, up to 15 additional MRF-300’s can
be installed to control them (thus allowing up to 90 identical components or
zones in one house).
IR Input for Keypads or IR Repeater Systems
The MRF-300’s rear panel IR input will relay IR Data from IR repeaters or Multi-
Zone Keypads to all IR line outputs (does not support IR routing).The 5V, 100
milliamp output will directly power some brands and models of keypad directly.
