To turn on phantom power on the ASP4816 requires some taking apart of the console first. You need to open up the main panel to allow access to the meter bridge, then it is a case of soldering a wire to link 48V.
To start you need to watch the following parts of the video which illustrates how to open up the console:
- 0s - 2m 40s
- 5m 57s - 6m 51s
NOTE: The whole module does NOT need to be removed to carry out this process.
Once you have access to the meter bridge circuit boards, a wire needs to be soldered across "LK1" on the 10800-1 board.
