Contents IMPORTANT Page Section In order to comply with current European safety regulations it is essential that the Naim loudspeaker connectors supplied with amplifiers and loudspeakers are used. 1 Do not under any circumstances allow anyone to modify your Naim equipment without first checking with the factory, your dealer, or your distributor. Unauthorised modifications will invalidate your guarantee.
Introduction Naim Audio products are conceived with performance as the top priority. Careful installation will help ensure that their full potential is achieved. This manual covers all Preamplifiers, the Nait 5i Integrated Amplifier, all Power Amplifiers and all Power Supplies but begins with general installation notes and statutory safety warnings for all Naim Audio products. Product specific information begins in Section 5.
Introduction 4 General Installation Naim equipment is designed to offer the finest sound quality possible avoiding compromise wherever practical. 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. 4.
Preamplifier NAC 552 5 Installation and Operation The NAC 552 preamplifier does not incorporate an internal power supply and can be used only in conjunction with the NAC 552PS power supply. Diagram 6.3 illustrates connection of the NAC 552 to its power supply. The four transit screws on the underside of the NAC 552 case should be removed before use and must be replaced if the unit is to be re-packed and shipped. These transit screws must not be used in any other Naim product.
NAC 552 The remote handset mono (Flash) or mon (Narcom 3) key can also be used to set up automatic source switching. Automatic input switching only becomes operational on exiting from program mode by pressing and holding the handset prog key. Note: In a few cases some further equipment configuration may be required for auto switching to operate correctly on the AV input. Please contact your retailer or local distributor for advice. 5.
