APEX APP2 Phantom Power Supply
The Facts about “Matching” Phantom Power
Different condenser microphones specify different amounts of required phantom power.
As a rule these ratings can range from 48 volts all the way down to 9 volts. Fortunately
there is some flexibility in terms of matching phantom voltage to your mic. A rough rule
of thumb would be “more is better.” For example, a 24-volt condenser mic will run per-
fectly on 48 volts. In fact mics rated at as little as 9 volts can often operate on 48 volts,
but you might want to check with the manufacturer first. Conversely, a mic will gener-
ally perform best driven by not less than its rated voltage so, for a 48V mic, you would
obtain best results with 48 volts of phantom power.
