The mains earth 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. 19. 9 G eneral C o nne c tio ns no te s The Supernait negative input and output connections for each channel are common.

Do not stand it directly on top of another item of equipment. Care should be taken to ensure that it is level. The amplifier should be installed in its final location before connecting cables or switching on. ensure that the volume is turned down before switching on. a variety of power supply upgrade, alternative preamplifier and alternative or additional power amplifier options are possible for the naIT Xs. Diagrams illustrating the connection of some of these are shown in section 23. Contact your local retailer or distributor for advice on further alternative connection schemes. The NAIT XS incorporates an AV Bypass switch on its rear panel. The switch should only be set to "On" if the amplifier is to be used in conjunction with an AV processor in a home theatre system. In all other installations the AV Bypass switch should be set to "Off". Speaker and/or amplifier damage may occur if a signal is inadvertently connected to the NAIT XS av input while the AV Bypass switch is "On". operational features common to all preamplifiers and integrated amplifiers are described in section 28. operational features common to all preamplifiers and integrated amplifiers are described in section 28 22. 1 mains P owe r C o nne c tio n Connect the NAIT XS to a mains power socket using either the mains cable supplied or a Naim Power-Line. 2 2 . [. . . ] The three channels provide power to drive a centre channel speaker and a pair of either main front or surround channel speakers. audio line level input is via two 4-pin DIn sockets - one for the centre channel and one for the main or surround pair. The NAPV 175 should be installed on an equipment rack intended for the purpose and in its final location before connecting cables or switching on. switch on the source and preamplifier components, with the volume turned down, before switching on the NAPV 175.
