In a nutshell

Audio Ltd Envoy CXiR series systems are new generation radio mikes. They have same specs as 2020 series, but ergonomics is different and they are TV production focused. Transmitter TX Blue, 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. CXiR is a miniature multifrequency receiver (32), providing "true diversity" reliability, subcarrier-controlled squelch and a well-in-sight LED indicator for "no carrier". Its powering is external, generally camera provided. Settings are made with an infra-red CXiR remote control, which displays transmitter battery level. Audio Ltd. systems have several other advantages: 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.

TX Blue/CXiR 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. The CXiR receiver is equipped with an output and power sole for standard Betacam SX or DVCam DSR500 cameras, or else with an adapter providing an XLR3M (LF modulation) and an XLR4F (external powering). This Envoy series has the same specifications as RMS2020 series.
