Internal Reference: 009817
Beschrijving: The Sennheiser AB 2 is a UHF antenna booster designed to enhance the RF signal strength in Sennheiser wireless systems. It provides a gain of over 10 dB, improving reception quality when multiple Evolution wireless receivers share a single pair of antennas through the passive ASP 2 antenna splitter. The AB 2 operates within a frequency range of 518 to 554 MHz and features a high-quality selective booster that efficiently suppresses signals outside its passband.

It allows for daisy-chaining two boosters within one antenna lead to compensate for signal losses due to long antenna cables. The device is powered via a 10–18 V DC supply, typically provided through the antenna cable from the ASP 2 splitter's NT 1 power supply. Its compact design measures approximately 95 mm in length, 47 mm in width, and 21 mm in height, with a weight of around 60 grams. The AB 2 connects using BNC sockets and has an impedance of 50 ohms. This booster is an effective solution for enhancing the performance and reliability of Sennheiser wireless systems in various professional audio applications.
