P 3 Pr eamplifier Owner’ s Guide.
THANK YOU! Congratulations and Thank Y ou for Choosing Parasound Y our new Parasound P 3 Preamplifier presents the latest advancements in audio technology .
UNP ACKING AND PLACEMENT GUIDELINES FOR THE P 3 __________________________________________________________________________________________ CONNECTING A SOURCE COMPONENT TO THE BALANCED DIRECT 1 INPUTS.
UNP ACKING AND PLACEMENT GUIDELINES FOR THE P 3 Unpacking Y our P 3 Carefully unpack your P 3 from the shipping carton and remove all the enclosed accessories: • Remote control with two AAA batteries • Detachable AC cord • T wo T rigger control wires with a 2.
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.
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.
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.
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.
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.
Connect the input and output from your analog tape recorder to the T ape Play and Rec (Record) jacks of the P 3. See T ape Record and Play Circuitry in the T echnically Speaking section for more information.
CONNECTING AN EXTERNAL SIGNAL PROCESSING COMPONENT TO THE P 3 EXTERNAL LOOP JACKS Y ou can connect signal-processing equipment such as a frequency-shaping equalizer into the signal path of the P 3 via its External Loop Connections. See External Loop In/Out Connections in the T echnically Speaking section for more information.
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 wit.
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.
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.
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 .
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.
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.
CONNECTING THE P 3 AC POWER CORD AC Power Connections We recommend plugging your P 3 into the same AC outlet or power strip used for your accompanying audio components, especially the power amplifier and source components.
Tu rning the P 3 On and Off Y ou can turn the P 3 on and off with the On-Off button on its front panel, with the On and Off buttons on its remote control handset, or with an external DC source. Tu rning On the P 3 Press either the On-Off Button on the front panel or the On button on the remote control.
OPERA TING YOUR P 3 continued Selecting the Input Source Y ou can select the input source by repeatedly pressing the Source button on the front panel until the desired source name appears in the status display . Y ou can also select the desired source directly with the Source select buttons on the remote control.
OPERA TING YOUR P 3 continued Adjusting Bass and T reble T one T one Button Pressing the T one button on the front panel or remote control turns on the tone display . The illumination around the Bass and Tr eble buttons will also brighten. After pressing the T one button, you have about five seconds to make adjustments.

SERVICING YOUR P 3 If All Else Fails –Call Us for Help Call your Parasound dealer or Parasound’ s T echnical Service Department toll free at 1-866-770-TECH (8324). W e can often solve the problem with simple diagnostic tests you can perform yourself.
Balanced and Unbalanced Input Lines Recording and broadcast studios use balanced connections almost exclusively because of their inherent ability to reject noise and hum, assuring the best sound. Certain high quality preamplifiers and surround controllers built for residential use utilize balanced connections with XLR jacks for the same reasons.
TECHNICALL Y SPEAKING continued even risk overloading your speakers. Y ou can only adjust the bass and treble controls on the front panel. However , you can compare the sound with the tone controls on or off by pressing the T one button on the front panel or remote control.
