Powering the MDA1
The MDA1 can operate on a single 9 Volt battery or standard 48 volt phantom power. Whenever
phantom power is present on the XLR cable that is connected to the Balanced Output, the MDA1
plus will automatically switch to phantom power and disconnect the 9 Volt battery. In fact, when the
Battery switch is in, the MDA1 will sense the voltage and select which is greater. The Phantom/Battery
switch can be used to turn off the battery power when the unit is not in use.
