CONNECTION: Refer to Figure 1. [. . . ] The PI9 takes a signal from a standard telephone jack and, via transformer isolation, connects to a pair of RCA jacks, or a stereo 1/8" (3. 5mm) jack. The isolation keeps the output signal separate from the telephone line, and will not keep the line open unless the HOOK switch is in the ON positin as described later in the guide. Applications for the PI9 include broadcast, conference rooms, phone training, laptop presentations, or wherever a phone conversation needs to be recorded or heard over a PA system. However, you must ensure the signal level is no hotter than line level (+4 dB) or you will get distortion on the phone line. HOOK: OFF - ON An option on the PI9 is the ability to select whether or not the unit will hold a line open. A line being "held open" acts like a telephone is off the hook. ON is for the line to be left open and OFF is when the phone is hung up. WARRANTY The PI9 is a passive device for connecting a phone line to an audio system or vice versa.
