Balanced XLR Jacks and Their Pin Configuration
The balanced inputs of the P 3 use XLR jacks that conform 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 P 3 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.
Interconnect Cables and Their Color Codes
Common color codes for input and output jacks are red for right and white for left. Match the
colors at the outputs from your preamplifier or surround controller to the inputs on your P 3
so you’ll always hear the channels in their intended position.
Left and Right Direct 1 Input Jacks
Balanced connections will give you the best sound. If your source components have balanced
XLR output jacks, we recommend that you connect them to these inputs. 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 pair of balanced interconnect cables with XLR connectors
• An audio source component with balanced output connectors
Before Connecting
Leave the P 3’s AC cord disconnected until you have made all 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 Direct 1 Select switch on the P 3 is in its balanced (left) position.
To Connect
Plug the male end of one of the balanced cables into the right Balanced Direct 1 input
jack on the P 3
Plug the female end of this cable into the right channel output connector on your
source component.
Repeat steps 1 and 2 for the left channel.
