Do not under any circumstances allow anyone to modify your naim equipment without first checking with the factory, your retailer, or your distributor. equipment must not be exposed to dripping or splashing and no objects filled with liquid, such as vases, should be placed on the equipment. For your own safety do not under any circumstances open naim equipment without first disconnecting it from the mains. [. . . ] No low-pass filtering is applied. As an example, to assign the tuner input selection button to digital input 4 proceed as follows. To return an input selection button to its default analogue input, repeat the assignment procedure. For example, to return the tuner input selection button to its analogue input socket. iii) Press the av (illuminated) record selection button (which will extinguish). iv) Exit program mode. 19. 4 record outputs The selection buttons arranged along the lower bank select the source signal to be routed to the Supernait's record outputs. These separate source and record sections enable one source (a CD player, for example) to be listened to whilst the output from another (say, the tuner) is simultaneously selected for recording. note: Simultaneous and independent listen and record is not possible with two digital sources. e18 1 9 . 8 P ow er s u p p l y up g r a d es The Supernait preamplifier section can be upgraded through the connection of an external Flatcap, Hi-Cap or Supercap power supply. Diagrams illustrating power supply upgrades are shown in the following section. The Supernait SU P E R N A IT Integr a ted Ampl i fi er and external power supply must be switched off when connections are made. Switch on the external power supply and then the Supernait when all connections are complete. should always be connected regardless of what other equipment is used in conjunction with the amplifier. 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.
