IV：Connect to CCU

CCU board is optional.  Each FT-800 can has max four CCU channel. CCU channel can not talk with any other channel except front panel.

CCU channel board adopts transformer coupling. Audio signal can be either differential signal or Non-differential signal.

 After connection, FT-800 channel gain may need to be adjusted according to CCU I/O signal. 

The step is as follow:

  1. Turn off all the channels except CCU channel which is need to be adjusted . 
  2. Turn on the camera microphone . Meanwhile, FT-800 headset and camera headset both

 can hear each other.

  1. If the voice heard from FT-800 is not proper. Adjust the Input Level potentionmeter which 
    2. is beside RJ-45 connector, until the voice level which is heard from FT-800 is proper.
    4. If the voice heard from camera is not proper. Try the camera voice knob first. If it can not

     reach the proper level. Open the top cover.

    5. Adjust the Output Level potentionmeter which is at the middle of CCU board, until the

     voice which heard from camera headset is proper.

    6. Repeat step 1~6 for rest CCU channel.
