reading on wikipedia and i learned the following.
so - in midisense ADio, is the signal ground connected to the power ground?Voltage is a differential quantity, which appears between two points having some electrical potentials. To measure the voltage of a single point, a reference point must be selected to measure against. This common reference point is called ground and considered to have zero voltage. This signal ground may or may not actually be connected to a power ground.
the reason i ask is that i have tons of phr-2 connectors lying around. i'd need phr-3 connectors in my brainchild. i'd just like to know so i could order some phr-3 housings and terminals now.
