[. . . ] Instruction Manual P-2000 7. 1 Channel Preamp/Processor/Tuner 2 Warnings P-2000 7. 1 Channel Preamp/Processor/Tuner Please Read First Outdoor Antenna Grounding­If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna-discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. Lightning­For added protection for the unit during a lightning storm, or when the unit is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage due to lightning and power-line surges. Power Lines­An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall onto such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal. [. . . ] Use the < and > buttons to cycle through the speaker options for the FRONT speaker. The following options are available for each group of loudspeakers: For FRONT you can select SMALL or LARGE For CENTER you can select SMALL, LARGE or NONE For SURR(OUNDS) you can select SMALL, LARGE or NONE For SURR(OUNDS) REAR you can select BS(LB), LB/RB or NONE LB/RB means you have a Left Back and Right Back rear surround speaker setup for use in a 7. 1 configuration. BS(LB) means you have a single centrally placed BACK Surround speaker for use in a 6. 1 (EX) type configuration, connected to the left back output. The Main Menu appears on the Front Panel Display and the OSD. The cursor on the OSD should be pointing to the Input Configuration menu and INPUT CONFIG appears on the Front Panel Display. 2. button once to select the Speaker Configuration For SUBWOOFER you can select ON or OFF button after you have made a selection. 5. Press the The cursor on the OSD should be pointing to the Speaker Configuration menu and SPEAKER CONFIG appears on the Front Panel Display. 3. Press SELECT to enter the Speaker Configuration menu. Repeat steps 4 and 5 until you have completed selecting the speaker type for each loudspeaker in your system. 6. Press the button when you are finished to select the Front Crossover (XOVER) menu. The Speaker Configuration menu appears on the Front Panel Display and the OSD (see figure 2). The first three settings in the Speaker configuration menu deal with the type of speakers you are using in your system. It is very important that you understand what is meant by the LARGE and SMALL settings in this menu. They do not refer to the physical size of the speakers, but to their ability to handle very powerful deep bass. Most loudspeaker systems on the market should be classified as Small, since they do not have the capability to handle the often extraordinary amount of deep bass content that film soundtracks can contain. It is strongly recommended that you consult your loudspeaker instruction manual regarding the capabilities of your particular system with regard to low bass/low frequency reproduction. Please note that all THX certified loudspeaker systems are classified under this method as SMALL since a subwoofer is required for any THX certified loudspeaker system. In any case you should consider using a subwoofer for any system which you expect to effectively handle the low frequency dynamics of modern motion picture soundtrack sources such as DVD or HDTV feeds, and many other discrete multi-channel programming sources. If you aren't sure about your speaker's real world capabilities and you are using a subwoofer, choose Small, since this will insure that all the appropriate low frequency information is directed to the subwoofer where it can be most effectively handled. The Front, Center and Surround Crossover menus are used to independently set the internal High Pass filter of the P-2000's Cirrus Triple Crossover for each of these three speaker groups. 7. Use the < and > buttons to adjust the Front Crossover. The crossover settings appear as follows as you scroll through them: 40Hz60Hz80Hz100Hz120Hz150Hz You can scroll in either direction using the < and > buttons . Consult the material that came with your loudspeakers to determine the correct settings, if any are recommended. In general, if you are not sure about the frequency response of your speakers, we recommend you set the crossover at 80Hz, unless otherwise directed by the manufacturer. If you are using very small satellite speakers you may need to set the crossovers to 100 or even 120Hz. When correctly set, you should hear a smooth transition of lower to upper bass between the satellites and the subwoofer. 8. Press the button after you have made a selection. Repeat steps 7 and 8 until you have completed the speaker crossover settings for each group of speakers. 9. button to select the Return to Main Menu 10. Press the SELECT or MENU button to return to the Main Menu, or press the MENU button twice to exit the menu system. System Setup Instruction Manual 27 Channel Calibration The next step is to adjust the output level of each channel so that they are properly matched. [. . . ] Do not use abrasive cleaners, as they can damage the finish of the metal parts. Avoid spraying insecticides, waxes, polishing agents, or any aerosol product near the unit. When You Are Away If you will not be using your system for an extended period of time, it is always a good idea to turn the unit off using the Power Switch on the rear panel of the P-2000. This will prevent the automatic turn on circuits from accidentally turning the system on during your absence. Troubleshooting Your new P-2000 is designed to provide years of trouble free operation. However, the complexity of today's sophisticated surround sound systems means that you might encounter an occasional problem with your system involving the P-2000. [. . . ]
