User manual NAIM HI-CAP

[. . . ] This equipment generates, uses and can radiate radio frequency and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · reorient or relocate the receiving antenna. · Increase the separation between the equipment and the receiver. [. . . ] Some Naim transformers are large in size, making them relatively sensitive to such distortion, and it may be necessary to take account of transformer hum when siting your equipment. Transformer hum is not transmitted through the speakers and has no effect on the performance of the system; however, a separate mains circuit may reduce it. Such a circuit (ideally with a 30 or 45 Amp rating) will also generally improve system performance. Advice on the installation of a separate mains circuit should be sought from a qualified electrician. Do not substitute alternative mains leads and plugs to those supplied. They are selected to offer the best possible performance. 2 mains Pow er where fused plugs are used 13 amp fuses should be fitted. Fuses of a lower rating will fail after a period of use. Do not wire voltage dependent resistors or noise suppressors into mains plugs. They degrade the mains supply and the sound. 2. 1 mains Plu g w i r i n g In some territories a mains plug may need to be fitted to the supplied mains lead.

This can lead to circumstances that may be unfamiliar. The notes that follow contain advice specifically related to naim equipment as well as more general warnings about the use of domestic audio products. Please read them carefully. 3. 4 radio Interference 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. In situations of extreme radio interference Naim equipment may be unsuitable. 3. 1 s iting The e q u i p m e n t In order to reduce the risk of hum audible from the loudspeakers, power supplies and power amplifiers should be located a reasonable distance away from other equipment. The maximum separation distance for connected equipment is that allowed by the standard interconnect lead. [. . . ] 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. e2 C D 5 5 5 P S, Supercap and XPS Power Supplies 4 Power s upply Installation Power supplies should be installed on an equipment rack intended for the purpose in their final location before connecting cables or switching on. ensure that power amplifiers are switched off and the preamplifier volume is turned down before power supplies are switched on. The power buttons are located on the front panel. Connection diagrams will be found in the appropriate preamplifier or CD player owners manual. [. . . ]
