Audio Technica ATW-F500DE2 Band Pass Filter Pair

The Audio-Technica ATW-F500DE2 is a passive band-pass filter pair designed to reduce out-of-band interference in wireless microphone systems. Installed between antennas and receivers, these filters block unwanted frequencies that can saturate or overload RF front ends, improving system dynamic range and reducing interference.

Each filter operates in the 470–530 MHz band with industry-standard BNC connectors. They are purely passive and require no power or user configuration—installation is simply in-line between the antenna and receiver systems. Their compact size and reliable performance make them ideal for live sound, broadcast, and multi-channel RF setups.

Used in tandem, this filter pair ensures that only desired frequencies pass to the wireless receivers, protecting system integrity and enhancing signal clarity in demanding RF environments.
