AUDIO LTD RX2000D RF Set + Lavalier
In a nutshell

Audio Ltd RX2000D radio set. Introduced about fifteen years ago, Audio Ltd wireless systems have largely contributed to the wide development of radio mike use. TX2000 transmitter is powerful and very autonomous; it accepts line and microphone inputs and its LF circuit is remarkable with low-cut filter and discrete compression/expansion system. RX2000D is a reliable first-generation diversity receiver. It is equipped with subcarrier-controlled squelch, LED indicator for transmitter battery level and headphone output. Audio Ltd. systems have several other advantages: 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.
TX2000/RX2000D is dual-channel (F1, F2) system and RX2000D is a portable but not miniature receiver. It is nevertheless very sturdy and reliable, so much so that many owners don't want to work with the newer range. Because of its size, it is not fit for video camera connection. Transmitter accepts any type of lavalier, as well as condenser microphones using VDB L-48 accessory, or dynamic microphones with VDB L-dyn adapter.
