The new MRI 15 Portable FM Transmitter is specially designed for the following applications:
- Civil defense organizations
- Armed forces and security forces
- Electoral campaigns
- Religious orders
- Small communities
The MRI 15 is made of a 4-audio-channel mixer and an externally synthesized FM transmitter that can provide a 15W RF output signal. This unit has been designed to be used as emergency radio station, really easy to use and to install. It can be also used as small radio station in rural areas, or eve as exciter of a more powerful transmitter. On its LCD Display, transmission parameters like forward power, reflected power and FM-band modulation level (in 10 KHz steps) can be visualized. The MRI 15 works with internal or external 12VDC power supply, or with AC power supply between 110 ~220VAC. Due to its excellent performance and versatility the MRI 15 is an outside radio broadcasting unit unique in the world.
