Powering S direct plus

The S direct plus can operate on a single 9 Volt battery or standard 24-48 volt phan-

tom power. Whenever phantom power is present on the XLR cable that is connected 

to the Balanced Output, the S direct plus will automatically switch to phantom power 

and disconnect the 9 Volt battery. In fact, when the Battery switch is in, the S direct 

plus will sense the voltage and chose which ever is greater. The Phantom/Battery 

switch can be used to turn off the battery power when the unit is not in use.
