The external mic jack is designed for low impedance balanced mics. This input provides
phantom power for mic that need it and can be safely used with mics that do not require it.
We recommend using only high quality cables equipped with the appropriate connectors.
Powering up
When power is applied, the Power switch will illuminate indicating the unit is on. It is important
to remember to turn the HeadAmp 4 Pro output controls to minimum before connecting to any
of the outputs. The HeadAmp 4 Pro has the ability to add gain to its' input signal. This can
cause the HeadAmp 4 Pro to produce a “thump” on power up and power down.
