CX

iR

 Diversity

Receiver

The CX

iR

 is a multi-frequency UHF diversity

receiver, designed with a range of modular adapters

to allow it to be mounted internally in the latest

camcorders from Sony, Philips, and Ikegami.

Alternatively, a universal adapter fitted with the six-

pin Lemo socket is available allowing the CX

iR

 to be

used externally with camcorders that do not provide

a built-in wireless microphone receiver slot. Also,

the CX

iR

 can be used as a portable documentary or

ENG receiver. All settings can be read or changed

via infra-red control using the Switch

iR

.
