CONNECTING YOUR JC 2 continued
OTHER CONNECTIONS
12V Trigger Out
There are four 12 volt trigger outputs. These can be used to turn on power
amplifiers and other equipment that are equipped with automatic turn-on inputs.
Two of the 12 volt trigger output jacks labeled 1 and 2 are live whenever the JC 2
is turned on. The jacks labeled 3 and 4 are activated when you press the Trigger On
button on the remote control. Triggers 3 and 4 are always off when the JC 2
is powered off.
Connect the JC 2 12V output jack to the triggered component’s trigger input jack
using the provided trigger wire with the 2.5 mm sub-mini plugs.
Note: Most Parasound Power Amplifiers are equipped with a 2.5mm 12V trigger input jack. The
trigger voltage source is DC and the trigger plug tip is + (positive) and its sleeve – (negative).
The JC 2 combined trigger output maximum current capability is 150mA total.
External Remote Input
Your JC 2 is compatible with most popular infrared repeater systems for remote
control operation from another room or when the JC 2 is installed in a cabinet
where its remote handset signals cannot reach its front panel remote control
sensor. The External Remote Input connector is a standard
1 /
8
” (3.5 mm) “mini”
jack. The center conductor (plug tip) is for + and the outer conductor (plug sleeve)
is for – . Your Authorized Parasound dealer or custom installer can recommend a
compatible IR repeater system.
RS-232 Serial Port
This 9-pin female DB9 connector is a full-duplex serial port. This permits
the JC 2 to communicate in two directions with home automation and
control systems such as Crestron, AMX, Control4, Niles and Elan. When
the JC 2 is connected to such a device, it can be controlled and its status
monitored from keypads or touch-screen panels throughout your house. The capabilities of such
connections, and the programming and interfacing needed will depend on the automation system
you select; consult your Parasound dealer or custom installer for more information regarding
interfacing an external control system to your JC 2. The complete RS-232 protocol can be found at:

AC Power
The IEC standard AC cord supplied with your JC 2 is an audiophile-grade
component. Please connect it directly to an AC wall outlet that is always
“live.” If possible, plug your JC 2 into the same AC outlet that your
accompanying audio components (particularly your source components
and power amplifiers) are plugged into. If different AC outlets are used
the ground potential may be higher or lower between the outlets,
resulting in audible hum.
