Sennheiser A 3700 Active Antenna
The Sennheiser A 3700 is a high-efficiency omnidirectional receiving antenna with a built-in preamplifier, designed to boost wireless microphone signals and compensate for cable losses. Featuring adjustable gain settings and easy stand mounting, it ensures reliable reception for professional audio applications.
Enhance your wireless audio system with the Sennheiser A 3700 omnidirectional receiving antenna. This antenna provides consistent reception from all directions and includes a built-in preamplifier with selectable gain levels (5, 10, or 15 dB) to counteract signal loss in long antenna cables. An LED indicator clearly shows the selected gain, and in the absence of power, the antenna automatically switches to Bypass mode (-3 dB) to allow unamplified signal pass-through.
The A 3700 is compatible with EM 2000/2050/373x receivers and the ASA 3000 splitter and can be conveniently mounted on standard microphone stands using the included 5/8" thread, reducible to 3/8". Its broadband omnidirectional design ensures optimal signal coverage across the entire 470-866 MHz frequency range, making it ideal for live sound, theater, and broadcast applications.
