This manual begins with statutory safety warnings and general installation tips for all Naim Audio products. Product specific information begins in Section 6. 2 CONTENTS Page Section 1 1 1 1 Equipment Installation Normally your Naim equipment will have been installed by the dealer who sold it to you even if you live outside their immediate vicinity. Your dealer is responsible for making sure that the system sounds exactly as it should and information given here is not intended to reduce this responsibility in any way. 2 3 2 Cables and Connections Please do not modify the standard interconnect cables supplied with your Naim equipment. [. . . ] · Increase the separation between the equipment and the receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. · Consult your Naim dealer or an experienced radio/TV technician for help. 3 NAP 500 6 Installation and Operation The NAP 500 and NA PS500 should be installed in their final operating locations before connecting cables or switching on. Switch on the source and preamplifier components, with the volume turned down, before switching on the NAP 500. The NAP 500 power button is located on the front panel of the NA PS500 Power Supply. Care should be taken when siting the NAP 500 to ensure that the top and bottom ventilation grids are not blocked e. g. The NAP 500 is very heavy and care should be taken when lifting or moving it. Make sure that the surface it is to be placed on can support the full weight. 6. 1 connections notes The negative input and output connections for each channel are common. The mains earth (ground) should always be connected regardless of what other equipment is used in conjunction with Naim power amplifiers. 230V - 50/60Hz 160 x 432 x 375mm 87 x 432 x 314mm 25. 0kg 15. 4kg 5 nc ch 2 NAP 300 8 Installation and Operation The NAP 300 and NA PS300 should be installed in their final operating locations before connecting cables or switching on. Switch on the source and preamplifier components, with the volume turned down, before switching on the NAP 300. The NAP 300 power button is located on the front panel on the NA PS300 Power Supply. Care should be taken when siting the NAP 300 to ensure that the underside fan inlet and rear outlet are not obstructed e. g by carpet in the case of the inlet. The NAP 300 is very heavy and care should be taken when lifting or moving it. Make sure that the surface it is to be placed on can support the full weight. 8. 1 connections notes The negative input and output connections for each channel are common. The mains earth (ground) should always be connected regardless of what other equipment is used in conjunction with Naim power amplifiers. This only grounds the case and the electrostatic screen within the transformer, and is not connected to the signal negative. In order to avoid hum loops, the signal negative of the whole system should be connected to the mains earth (ground) in one place. This should be the primary signal source. 8. 2 protection notes In the NAP 300 the fan speed is increased in response to an increase in amplifier dissipation. If the amplifier reaches 70°C due to prolonged running at high level or to airflow being blocked, the output will be interrupted and the fan will run at full speed until it has cooled down. It is not necessary to switch the amplifier off, but it may be advisable to mute the preamplifier or turn the volume down to avoid surprises when it comes back on. OPERATION OF THE AMPLIFIER'S THERMAL PROTECTION SUGGESTS PROLONGED USE AT TOO HIGH A VOLUME LEVEL. [. . . ] This should be the primary signal source. 14. 2 protection notes If the amplifier's external case reaches 70°C due to prolonged running at high power, the mains supply will be interrupted and the illuminated logo will switch off until the amplifier has cooled down. OPERATION OF THE AMPLIFIER'S THERMAL PROTECTION SUGGESTS PROLONGED USE AT TOO HIGH A VOLUME LEVEL. THE VOLUME SHOULD BE REDUCED. 14. 3 loudspeaker cable and connectors Only Naim Audio speaker cable should be used to connect a loudspeaker to the output of the amplifier. Custom Naim Audio loudspeaker connectors are supplied to make the connection. [. . . ]
