In a nutshell

Audio Ltd DX2020 radio set. Introduced about fifteen years ago, Audio Ltd wireless systems have largely contributed to the wide development of radio mike use. Transmitter TX2020, powerful and very autonomous, offers a choice of 32 frequencies ([F1, F2]x16); it accepts line or microphone input, and its LF circuit is remarkable with low-cut filter and discrete compression/expansion system. DX2020 is a miniature multifrequency receiver (32), providing "true diversity" reliability, a subcarrier-controlled squelch and a LED indicator for transmitter battery level. Audio Ltd. systems have several other advantages: transmitter and receiver easy switching on and off, sturdy connectors easy to wire, a range of clever accessories developed by VDB such as L48 or Spider Box. So it's easy to understand why these systems have replaced their competitors on production shoots, documentaries or ENG.

TX2020/DX2020 are multichannel and miniature. Transmitter accepts any type of lavalier, as well as condenser microphones using VDB L-48 accessory, or dynamic microphones with VDB L-dyn adapter. Thanks to its small size, receiver DX2020 is ideal for video camera connection; it is then camera powered via VDB OL-HRSA cable.
