Connections
Input Connectors
The PH9 provides a pair of input connectors.
Connect the output of your tonearm/
turntable to these connectors.
Output Connectors
A pair of single-ended main outputs
are provided. Connect the output
of the PH9 to an input of your
preamplifier or integrated amplifier.
A.C. Power Connection
It is important that the PH9 be connected
via its supplied 15 amp IEC 14-gauge
power cord to a secure, dedicated A.C.
power receptacle. Never connect to
convenience power receptacles on
other equipment. Only use the power
switch on the front of the PH9 for On/
Off control of the preamplifier, or the
IR input, RS232 or remote control.
RS-232 Input
The RS-232 input allows connection of
a control or automation system.
IR Input
The IR input allows a remote IR sensor
or repeater system to be connected to
the PH9 for control purposes, utilizing
a standard mono 1/8” connector.
Important
Use the best available speaker wires
and interconnects. Audio Research
cannot emphasize this enough. As
better components and systems are
developed, it becomes increasingly
important to avoid the limitations of
inferior system interconnections.
It is important sonically that your entire
system be connected so that the audio
signal arriving at the speakers has correct,
or ‘absolute’ polarity (i.e., non-inverted).
