When making connections, make sure there is no strain or tension on any wires that could cause them to pull loose later on. [. . . ] It is a convenient way to listen privately without the need to switch off your power amplifier. The LED above the mute button will illuminate when the output has been muted. Polarity Invert Function The remote control handset also allows you to select 180o polarity inversion for both channels. Correct absolute polarity insures that loudspeaker cone movement is consistent with the original recording. While correct polarity may not be noticeable in many multitrack recordings, you will detect an audible improvement from maintaining correct polarity in well recorded performances. Absolute polarity switching is only available from the remote handset; the front panel LED will illuminate when the polarity has been inverted. Volume Control Your P/LD-2000 employs a precision Alps potentiometer for volume adjustment. The slight resistance you feel when manually turning the volume control is from the gearing of its remote control actuator motor. Adjust your power amplifier gain controls (if so equipped) to accommodate a 11 AM - 1 PM setting of your P/LD-2000 volume control knob for your most frequent listening level. -4- Balance Control Adjust relative left and right volume levels with this precision Alps 4-gang control. If clockwise rotation favors the left channel speaker as you face it, you have reversed right and left hookups between your preamp and power amplifier or between your power amplifier and speakers. Input Select Buttons Press the button for the source you wish to hear. Remote Control The remote control handset duplicates every function of the front panel controls with the exception of the balance control. Use only AA alkaline batteries in the handset and observe the correct polarity which is marked in the case. Your remote control handset also includes controls for the matching Parasound T/DQ-1600 FM/AM Broadcast Reference tuner. This convenient feature allows control of both components with a single remote control. Whenever you turn your P/LD-2000 on it will select the same source and the same volume setting you were playing before the last time you turned it off. This is dependent upon leaving your preamp plugged into an AC outlet that is always live. Never interfere with the motorized operation of the volume control knob while it is moving by a command from the remote control handset. "Burning-In" Your P/LD-2000 Like many other great high end preamplifiers, your P/LD-2000 requires at least 72 hours of continuous operation after it is first turned on to sound its best. This gives various internal components and wiring a chance to "form" their optimum electron paths and pass complex musical information with greater definition, smoothness and transparency. Although your P/LD-2000 will sound spectacular when you first turn it on, you will find it worthwhile to reserve your final judgment until you've listened after a more few days. You'll discover additional musical details you may not have imagined were present. [. . . ] The warranty excludes parts subject to normal wear such as fuses, laser pickups, or cosmetic parts.
