Get A Well Built And Reliable Transmitter With The Rolls HR70 FM Broadcast TransmitterThe 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 87.5 to 108 MHz 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 micro power RF transmitter and requires no FCC license, for it to function properly good RF practices still apply. The wire antenna that is provided is set up for the middle of the band or about 92MHz. For any transmitter to operate at its' best, it must be earth grounded. You can think if it sort of -"pushing-" the signal against the earth. Range can vary widely, depending on grounding, antenna placement, obstructing building/walls, etc.. People have reported ranges of 150 feet or so. Some experimenting may be required at your venue to find the optimum installation for your situation.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 microV/meter @ 3 meters (also measured as 48 dBuV/m).SPECIFICATIONSFrequency Response: 20 Hz - 12.5 kHzAntenna Impedance: 50/75 ohmInput Impedance: 100K ohms Unbalanced, 600 ohms BalancedIndicators: Power LED and Clip LEDInput/Output jacks: XLR balanced INPUT RCA unbalanced input and outputPower: 12 - 15 VDC 500mA 5 x 1.2 mm DC Jack - Center NegativeTuning Range: 87.5 - 108 MHzDimensions: 6.75 -"w x 4.25-"d x 1.6-"hSimple way to broadcast signals over FMMax Power Output: 4mW 75 ohmAntenna Jack: normal female BNCClean simple designAll metal chassisIncluded DC power supply Manufacturer: RollsModel: HR70SKU: I498438-10-WHXAWe are Chuck Levin's Washington Music CenterMaryland, Virginia, and Washington DC's legendary music shop.
