Description

Digital FM Radio Transmitter with +48V Phantom Power, and Mic, Line, and Auxiliary Inputs

The HR70 is a digital display analog FM transmitter. Apply a signal to the XLR or RCA inputs of the HR70. Select what frequency you would like to broadcast those signals on and you are now sending signals via FM radio, assuming the antenna is connected properly. The HR70 also has a talk over circuit built in. Even though the HR70 is a micropower RF transmitter and requires no FCC licence, for it to function properly, good RF practices still apply. For any transmitter to operate at its best, it must be earth grounded. You can think of it as "pushing" the signal against the earth. Range can vary widely, depending on grounding, obstructing building/walls, etc. We have had people report ranges up to 125'. Some experimenting may be required at your venue to find the optimum installation for your situation. Antenna included.

FAQ:
What is the maximum distance an FM transmitter can broadcast without a license? The quick answer is approximately 200 feet for an FM Transmitter covered under Part 15 (Read FCC Public Notice dated July 24, 1991). The full answer is much more complicated than that: 250 µV/meter @ 3 meters (also measured as 48 dBuV/m).
