Audio Input & Output Connections
Balanced XLR Input Jacks
In most systems balanced XLR connections will give you the best quality sound because of their ability to
reject noise. Refer to the Balanced and Unbalanced Lines in the Technically Speaking section for additional
information and why we recommend using balanced lines.
Note: Using balanced XLR input connectors results in a 6 dB higher volume level
compared with using the RCA input jacks. This is a noticeable level increase.
Unbalanced RCA Input Jacks
Use these inputs if your preamplifier doesn’t have balanced XLR output connectors or if you simply prefer to
use unbalanced connections.
Balanced/Unbalanced Selector Switch
Place the switch in the position for the input type you will be using.
Note: The Balanced/Unbalanced switch is not an input selector. Its function is purely to
optimize the signal to noise ratio for each type of input. You should not connect both the
Balanced and Unbalanced jacks at the same time with the expectation of switching
between two different devices such as a preamp and a surround processor.
Balanced XLR Pin Configuration
The JC 1+ XLR jacks conform to the industry standard of:
Pin 1: Ground Pin 2: Positive (+) Pin 3: Negative (–).
XLR and RCA Output Jacks
These Output jacks enable the incoming audio signal to pass along or “daisy chain” the incoming
audio signal to an additional amplifier for bi-amping or for connecting a powered subwoofer. The XLR
input signal is available at both the XLR and RCA Output jack.
The XLR and RCA Output jacks are not
affected by the Gain switch setting.
