Simply connect the PI9 to a standard telephone connection, and it will use transformer isolation to direct the signal to a pair of RCA jacks or the 3.5mm mini jack. The transformer isolation keeps the phone line separate from the output signal, meaning the unit won't keep the phone line open unless the internal jumper is moved.
Note! The PI9 only works with standard RJ11, single-line phones. It does not work with VOIP systems or any digital phone systems.
