3.0 Warnings
Naim equipment is designed to offer the finest sound quality that can be achieved, avoiding compromise wherever
possible. This can lead to circumstances that may be unfamiliar. The material that follows contains advice
specifically related to Naim equipment as well as more general warnings about the use of domestic audio products.
Please read it carefully.
The transformers in Naim power amplifiers and power supplies may sometimes make a mechanical noise caused by
distortion of the mains waveform. Naim transformers are large in size and have heavy gauge secondary windings
making them relatively sensitive to such distortion. A separate mains circuit for your hi-fi system may reduce the
effect while also giving an overall improvement in sound quality. It may be necessary however to take account of
mechanical transformer noise when siting your equipment.
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. If there is a known problem
in your locality it is advisable to arrange for a home demonstration before purchase to find out if Naim equipment
is likely to be affected. Susceptibility to radio frequency interference is related to the wide internal bandwidth
necessary for high sound quality. Systems incorporating moving coil phono preamplifiers and active crossovers are
more likely to suffer. 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.
Your Naim hi-fi system can be damaged by lightning. Power amplifiers are particularly at risk and should be turned
off when there is risk of lightning strike. For complete protection all mains plugs and any aerial cables should be
disconnected when not in use.
Equipment must not be exposed to dripping or splashing and no objects filled with liquid, such as vases, should be
placed on the equipment.
