Phantom Power: 48V Jumper Settings
Phantom power is enabled by fitting the link to short pins 1 and 2. If not required (i.e., using a dynamic mic) then it should be
set to short pins 2 and 3. Pin 1 position can be ascertained by looking for the square pad on the solder side.
Note that the standard Talkback mic on the console (wired to T1) is a condenser type which requires phantom power.
The following table shows the mapping of the jumpers:
