System Overview
The ADX announce system consists of the following elements:

One or more ADX-2400 frames which serve as the 'head end' or truck end of
the system, and provide all inputs and and outputs for the truck or control
room. These units are available with analog, AES, or MADI I/O.

One or more ADX-120 Announce Boxes or ADX-140 Interface Frames which
function as the remote units in the booth or other remote location.

ADX-8000 or other 48-volt power supplies as required to power the ADX-120
units. The ADX-140 and the ADX-2400 have internal AC-operated supplies,
although the ADX-140 may also be powered over the CAT5 cable from an
external 48-volt supply (such as the ADX-8000).

Network infrastructure as required, consisting of standard layer-2 Ethernet
switches, fiber optic elements, media converters, fiber and copper
interconnects, etc. This is referred to in this manual as 'the network'.
Each ADX-2400 unit can support up to four ADX-120 or ADX-140 units, in any
combination.
The remote devices are identified by the ADX-2400s by a SYSTEM ID number,
which is set by a two-digit rotary switch on the remote device (rear panel of the ADX-
120, front panel of the ADX-140). Each remote device must be set to a unique
system ID (01-99).
The desired remote devices are designated in the ADX-2400 menu to be 'UNIT A',
'UNIT B', 'UNIT C' and 'UNIT D' for that ADX-2400. This is what determines the
audio routing; for example which microphone signal comes out of the 'Mic A1' output
of the ADX-2400. The microphone signal that comes out of that output would be the
headset mic ("Mic 1") from the ADX-120 which has its system ID switches set to
match the number assigned as 'Unit A' in the ADX-2400 menus.
Note that network wiring has no bearing on the audio routing. An announce box
can be plugged in anywhere on the network, into any cable, and the routing will
remain constant. This could be very useful if you had to move an announce
position to a second location. All faders, IFBs, PLs etc. would remain the same at
the second location without any duplication or re-patching/routing at the truck.
As another example, if you needed to swap the color and play-by-play positions for
some reason, you could just change the System ID switches on their announce
boxes. All mikes, IFBs, talkbacks, etc. would be swapped automatically.
Note that the network which connects the system components is a true Ethernet
network, and may be as extensive and as distributed as required. It is not simply a
point to point system. Network nodes might be in a booth, mobile unit, locker room,
sideline, and interview studio; all connected by a combination of fiber and Cat5
cable.
