power is input (not generated on the board) and
switched on and off via the on-board Phantom
Power switch. Note that the ground return for
+48V phantom power is via the CHAS (chassis
ground) connector. The +5V input is regulated on
board to 3.3V and supplies the digital logic.

measure performance of the mic preamp circuit in

board while the GUI software is running as this
will sometimes crash the Windows drivers.
General Purpose Outputs (GPO)
P6 is conveniently located near the prototyping
area, so the user can easily connect optional
circuitry to them. Note that the GPO pins are also
connected to LEDs, D1-D4, and pull up and pull
down resistors which set the 5173 device address
during reset. Consideration must be given to how
any application circuitry that is added interacts
with these other functions.
