FM STL LINK

FM Radio Studio to Transmitter Link

Overview

The MT-MR Platinum Radio Link System is an STL (Studio-Transmitter Link) used to transport FM radio information from Production Studios to a distant Transmitter station.
It is available in all frequency bands below 1 GHz.
This Radio Link not only can work as STL point-to-point system, but it can also work as multiple-repeater Relay system in any configuration. Provision of an audio dropout at each repeater station allows the creation of regional chains having multiple Transmitter Stations.

Highlights and Benefits

LCD

LCD reading of frequency (6 digits), direct/reflected power, modulation level and component of the pilot signal (19KHz) while transmitting.

Transmitter

The receiver has double conversion and externally synthesized with the same characteristics as the transmitter

Balanced Mono

Balanced mono, stereo (MPX) and 3SCA inputs.

SWR

SWR fold - back protection
