9. may be unfamiliar The material that follows contains advice and information specifically related to Naim equipment as well as more general warnings about the use of domestic amplification so please read it carefully The transformers in the power amplifiers and power supplies may sometimes make a mechanical noise caused by the distortion of the mains house current Naim transformers are large in size and have large gauge secondary windings making them quite sensitive to this distortion A separate spur fram your consumer unit for your hi fi system can often reduce the effect while also giving an overall improvement in sound quality but it may be necessary to take account of mechanical trans former noise when siting your equipment In some circumstances you may experience radio frequency interference depending on where you live and the earthing arrangements in your home Controls on broadcasting in some countries allow very high levels of RF and the choice and especially the exact siting of equipment may become critical If there is a problem in your area arrange for a home demonstration before purchase to find out if your Naim equipment will be affected RF interference is related to the wide internal bandwidth which is required for good amplification and in general moving magnet preamplifiers and passive systems are less likely to suffer An RF kit is available for some Naim equipment but sound quality will be pro gressively
