inlet. The compression meter will rise to about ½ way. Now
switch out Standby and the meter will go to 0. If it ends up

Do not adjust the little screw on the front of the meter. This
just changes the angle of the needle when the unit is cold,
when it should be horizontal.

48v to both mic channels but power is disabled when the
input selector is in Line mode on the individual channel.
You are now ready to go, so
