POWERING UP THE M63

When phantom power (48V) is supplied to the M63, the LEDs will blink red and green 

to indicate that the unit is receiving power. Following the power-up sequence, the 
LEDs will behave according to the setting specified by the DIP switch configuration.

*When connecting to a DSP, DIP switch 3 is always set to the left position.
