9.2 

The Receiving Equipment 

 
The  RFX-RMT-II  transmitter  may  be  used  with  a  variety  of  RF  Central  digital  receivers 
including: 
 

  RFX-RMR, RMR-II series rack-mounted receivers 

  RFX-PMR, PMR-II series portable receivers 

  RFX-RMRT, RMRT-D rack-mounted receivers 

  RFX-MDR-PC 

  RFX-RMR-X6 diversity receivers 

 
Full details of the operation of the receivers are given in the associated manuals 
 
When used with the 

RMT-II transmitter, the RMR / RMR-II, PMR / PMR-II, RMRT / RMRT-D, 

and RMR-X6 digital receivers produce four audio channels (analog and AES3 digital) together 
with SDI and composite video outputs.  These receivers also have an ASI output. 
 
Check that audio, video, and DC cables are of sufficient total length and are in good condition.  
If  extension  cables  are  necessary,  ensure  that  the  connectors  are  compatible  and  of  good 
quality to avoid problems at the site. 
 
Check that the receiving antenna / receiver interfaces are clean and free from dust and other 
unwanted materials. 
 
If tripods are to be used to mount the equipment, make sure that some means of securing the 
tripod  or  weighting  it  down  is  provided.    Gusty  wind  conditions  may  put  installations  at  risk, 
particularly when parabolic antenna dishes are to be used. 
 
Check  that  the  receiver  channel  frequencies  are  compatible  with  those  of  the 

RMT-II 

transmitter and set the channel selector switch to the channel number required.  The receiver 
is labelled with channel number and frequency information.  
 

9.3  Transmitter / Receiver Tests 

 

Whenever  practical,  set  up  the  system  and  test  it  before  leaving  for  the remote  site  to 
ensure that all components of the system are working properly.  Checking the system, 
making necessary adjustments, and taking corrective actions ahead of time, will pay off 
later when setting up at the remote site.
