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 sixpin Lemo socket is available allowing the CX

changed via infra-red control using the Switch

iR.
