Setting up Truck End Routing in the ADX-2400 (Channel Setup)

The ADX-2400 at the truck has routers which select the following:



Talkback

  paths  from  the  announce  boxes  to  physical  Talkback  outputs.  

Mixes may also be selected so that external talkback mixing is not required.



Physical 

IFB  inputs

  at  the  truck  to  the  various  IFB  outputs  on  the  ADX-

120/140 units.  One physical input may feed multiple IFB outputs.



Physical 

PGM  inputs

  at the truck  to the various PGM outputs on the ADX-

120/140 units.  One physical input may feed multiple PGM outputs.



Four-wire 

PL  Ports

  to  the  various  PL  channels  on  the  ADX-120/140  units.  

Any PL channel on the ADX-120/140s may be assigned to any four-wire port. 
The appropriate mix-minus signals will automatically be generated, similar to 
the 'party-line' function in the Adam intercom systesm.

These selections are made by the 'Channel Setup' buttons on the front panel of the 
ADX-2400.

There 48 outputs which may be selected by the OUTPUT SELECT button and knob.

The first 24 are the rear panel outputs.  These are referred to as 'Local' outputs 1-
24.  1-8 are the Microphone outputs, 9-16 are the Talkback outputs, and 17-24 are 
the output side of the four-wire PL ports.

The second 24 outputs are the 'Net' outputs.  These are the signals which are fed to 
the  Ethernet  network,  and on the  the  ADX-120/140 units.    Net outputs  1-8  are  the 
IFBs, 9-16 are the PGM feeds, and 17-24 are the listen side of the PL channels.

When the OUTPUT SELECT button is lit, the knob will scroll through the 48 possible 
outputs.    Additional  presses  of  the  OUTPUT  SELECT  button  will  step  to  the 
beginning of the next group of eight.

When a particular output is selected, press the SOURCE button to view or change 
the routing for that output.

Some  outputs,  such  as  the  microphones,  are  not  routable  and  have  no  selection 
options.    Other  outputs,  such  as  the  talkbacks,  have  many  choices.    The  menu 
choices should be self-explanatory.

Note that the LEVEL button may also be used to adjust the level of a given output to 
a  value  other  than  unity  (0.00dB).      We  suggest  that  this  only  be  used  when 
necessary  for  some  non-standard  condition,  and  that  unity  should  be  the  correct 
setting in most cases.
