Designed for Sennheiser EM 2000, EM 2050, EM 3731, EM 3732, and EM 6000 receivers, the A 3700 compensates for signal loss in long coaxial cable runs by boosting the received RF signal before it travels through the cable to the receiver.\u003c\/p\u003e \u003cp\u003eThe selectable gain settings allow the technician to match the antenna's amplification to the specific cable length and loss characteristics of the installation. Shorter cable runs may need only 5 dB of gain, while longer runs through thinner coax may require the full 15 dB. This flexibility makes the A 3700 suitable for both compact rack setups and large-venue installations where antennas are positioned far from the receivers.\u003c\/p\u003e \u003ch2\u003eKey Features\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eActive omnidirectional antenna with built-in amplifier\u003c\/li\u003e \u003cli\u003eAdjustable gain: 5 dB, 10 dB, or 15 dB\u003c\/li\u003e \u003cli\u003eWideband coverage: 470-866 MHz\u003c\/li\u003e \u003cli\u003eBNC connector with 3\/8-inch mounting thread\u003c\/li\u003e \u003cli\u003eDC power via coaxial cable from compatible receivers\u003c\/li\u003e \u003cli\u003eCompatible with EM 2000, 2050, 3731, 3732, and 6000 receivers\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eProfessional Applications\u003c\/h2\u003e\u003cp\u003eCommonly deployed in church, house of worship, and professional AV environments.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eRemote antenna placement with long coaxial cable runs\u003c\/li\u003e \u003cli\u003eLarge venue, worship center, and arena wireless microphone deployments\u003c\/li\u003e \u003cli\u003eTheater and broadcast installations with distant receiver locations\u003c\/li\u003e \u003cli\u003eTouring productions requiring flexible antenna gain settings\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e \u003ch3\u003eHow does the A 3700 receive power?\u003c\/h3\u003e \u003cp\u003eThe A 3700 is powered via DC bias on the coaxial cable from compatible Sennheiser receivers.
