YOU SHOULD KNOW 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 mat[...]

Left and Right Direct 1 Unbalanced Inputs If your best-sounding audio source component has only unbalanced RCA output jacks, connect them to the P 3 unbalanced Direct 1 input jacks. What Y ou’ll Need: • One pair of shielded interconnect cables with RCA plugs • A source component with RCA output jacks Before Connecting Leave the P 3’ s AC co[...]

Direct 2 Unbalanced Input Jacks The P 3 Unbalanced Direct 2 input jacks are for your next-best-sounding source component if the Direct 1 input jacks are already connected to another source. What Y ou’ll Need: • One pair of shielded interconnect cables with RCA plugs •A source component with RCA output jacks Before Connecting Leave the AC cord[...]

C onnecting a Source Component to the Aux Inputs on the P 3 The P 3 has a single Aux input, but two pairs of Aux jacks for either a phono or a line level source. The Aux Select switch determines if you’ll hear the source connected to the Aux-Phono jacks or the source connected to the Aux-Line jacks. It’ s possible to use both pairs of Aux jacks[...]

Connect the outputs of your CD player , tuner , or any other line level source to the CD and T uner jacks. All of the line level inputs are electrically identical.

For best sound performance, use the P 3 Balanced Line Output connections if your power amplifier is equipped with balanced inputs. What Y ou’ll Need: • One pair of balanced interconnect cables with XLR plugs • An amplifier with balanced XLR input jacks Before Connecting Leave the AC cord disconnected until you have made all connections to pre[...]

CONNECTING THE P 3 TO THE UNBALANCED INPUTS ON YOUR POWER AMPLIFIER Use these outputs if your power amplifier does not have balanced input connectors or if you prefer to use unbalanced connections. What Y ou’ll Need: • One pair of shielded interconnect cables with RCA jacks •A power amplifier with unbalanced input jacks Before Connecting Remo[...]

CONNECTING AN INFRARED REPEA TER SYSTEM TO THE P 3 The External Remote Input jack is for a wired infrared repeater system or system controller . It eliminates the need for a stick-on front panel IR flasher . There is also a Loop Out jack to loop or “daisy chain” to an additional infrared remote-controlled component. What Y ou’ll Need: • An [...]

TURNING ON THE P 3 WITH AN EXTERNAL TRIGGER VOL T AGE The P 3 can be turned on automatically when a trigger voltage is received from an external DC voltage source such as a system controller . What Y ou’ll Need: • A trigger cable with 2.5 mm sub-mini plugs (provided) • A component with an external +9Vdc to +12Vdc trigger voltage Before Connec[...]

The 12V T rigger Output jack generates its own +12 Vdc voltage whenever the P 3 is turned on so it can trigger other components such as a Parasound power amplifier . This output will provide up to 200 mA of current to trigger an external component. What Y ou’ll Need: • A second trigger cable with 2.5 mm sub-mini plugs (provided) •A component [...]

RS232 CONTROL The P 3 External Control connector is used only if you have a computer -based system controller . The P 3 is compatible with most system controllers.
