Thank you for your purchase of the PI9 PhonePatch II. 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.
The PI9 also works for putting audio onto a phone line. However,
you must ensure the signal level is no hotter than line level (+4
dB) or you will get distortion on the phone line.

INPUTS: 2 ea: Standard RJ11 phone jacks.
AUDIO LINE: Stereo RCA, 1/8" (3.5mm) jack
ON/MUTE switch: Connects or disconnects the Phone/Line jacks to
the transformer and the Audio output. With the switch in (ON) the audio
is active. When the switch is out (MUTE) the audio signal is muted.
Connect a standard telephone cable to an active telephone line,
and to the PI9 Phone Input. To pass the signal on to another
telephone, connect another standard telephone cable from the
PI9 Line jack to a telephone.
Connect either a stereo RCA cable, or stereo 1/8" (3.5mm) cable
to an AUDIO LINE output jack.
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 o the hook. ON is for the line to be left open
and OFF is when the phone is hung up.
