Parasound JC 1 Amplifier - Manual (Page 5)

Balanced Input Jack
Balanced connections will give you the best sound in most instances. If your preamplifier or
surround controller has balanced XLR output jacks, we recommend that you use them. Refer to
the Balanced and Unbalanced Lines in the Technically Speaking section for additional information
about why we recommend using balanced lines.
What You’ll Need:
• One balanced interconnect cable with XLR connectors
• A preamplifier or surround controller with balanced outputs
Before Connecting
Leave the JC 1’s AC cord disconnected until you have made all other connections to prevent
any surprise burst of sound.
Make sure that all your cables are long enough so they are not strained or stretched once
they are connected.
Make sure the Select switch on the JC 1 is in its Balanced Input (right) position.
To Connect
Plug the male end of the balanced interconnect cable into the Balanced Input jack on the JC 1.
Plug the female end of this cable into the desired channel balanced output jack on your
preamplifier or surround controller.
Repeat steps 1 and 2 above to connect additional JC 1s to other controller channels.

Balanced XLR Jacks and Their Pin Configuration
The balanced input on the JC 1 uses an XLR jack that conforms to the industry standard
of: Pin 1: Ground, Pin 2: Positive (+), Pin 3: Negative (--). The balanced outputs on some
components use terminals with 3 screws instead of XLR jacks. These are compatible with the
JC 1 as long as you match the bare wires to the corresponding pins on the XLR plug: + to
pin 2, - to pin 3, and Ground to pin 1.
