User manual NAIM SUPERLINE

[. . . ] In some circumstances, depending on where you live and the earthing arrangements in your home, you may experience radio frequency interference. Controls on broadcasting in some territories allow very high levels of radio frequency radiation and both the choice and exact siting of equipment may be critical. Susceptibility to radio frequency interference is related to the wide internal bandwidth necessary for high sound quality. A radio frequency filter kit is available for some Naim equipment but sound quality will be progressively compromised as more elements of the kit are fitted. [. . . ] Always use the power switch on the product rather than a mains outlet switch. It is essential that repairs and updates are only carried out by an authorised Naim retailer or at the factory by Naim itself. Many components are custom made, tested or matched and appropriate replacements are often unobtainable from other sources. Direct contact to Naim for service or update information should be made initially through Customer Services: Tel: Email: +44 (0)1722 426600 info@naimaudio. Naim equipment takes a considerable time to run in before it performs at its best. The duration varies, but under some conditions the sound may continue to improve for over a month. Better and more consistent performance will be achieved if the system is left switched on for long periods. It is worth remembering however that equipment left connected to the mains can be damaged by lightning. Please quote the product serial number (found on its rear panel) in all correspondence. The SuperLine moving coil phono amplifier is designed to extract the best possible musical performance from vinyl disc replay. The SuperLine contains no internal power supply and must be connected either to a Naim amplifier incorporating an appropriate power supply output, or to a dedicated Naim power supply. SuperLine output is muted for 2 minutes following switch-on to allow its circuitry to reach optimal status. Cartridge loading resistance and capacitance can be adjusted by inserting combinations of resistive and capacitive "load plugs" into sockets on the SuperLine rear panel. The SuperLine incorporates a suspension system to isolate its sensitive components from vibrational energy. The suspension system is protected during shipping by two transit screws. Once the transit screws are removed the SuperLine must not be inverted. Transit screw removal is best carried out once the SuperLine is installed in its final location and all connections are made. Two transit screws must be removed from the underside of the SuperLine before use and replaced if it is to be carried any distance, packed or shipped. SuperLine transit screws must not be used with any other Naim product. Damage may result if the SuperLine is inverted either during or after transit screw removal. [. . . ] Each load plug is constructed from a 5-pin DIN plug that contains the appropriate passive components. Seven standard load plugs are supplied - four resistive and three capacitive - to provide 20 combinations (including the default input loads applied when no load plugs are inserted). Note: In addition to the standard load plugs supplied, 470 and 560 resistive plugs are also available on request. Other values may also be created either by modifying standard plugs or manufacturing new ones. [. . . ]
