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. [. . . ] Note: A flashing mute indicator after switch-on indicates that the preamplfier power supply or link plugs are incorrectly connected. 10. 9 remote control The NARCOM 3 remote handset supplied with the NAC 282 duplicates all configuration options. The Flash handset will also control the NAC 282. See Section 16 for more information. 10. 10 defaults To restore all programmable settings to the factory defaults press and hold the remote handset disp key while the preamplifier is in program mode. The preamplifier will exit from program mode following this operation. 10. 5 volume and balance control The remote handset volume and balance keys provide some alternative control characteristics. A quick press and release of a key will adjust by a preset "nudge". A quick press and release of a key followed by press and hold will cause continual slow adjustment. Simple press and hold will cause continual fast adjustment. 10. 6 mute and mono Mute and mono functions can be controlled independently for source and record signals via the buttons to the left of the two banks of source and record selection buttons. Mute silences the output signal, while mono sums the left and right channels. 10. 7 display The NAC 282 front panel button display can be switched off by pressing the remote handset (in preamplifier mode) disp function. Any subsequent handset or front panel operation will temporarily restore the display. A second operation of the disp function will permanently restore the display. 13 NAC 282 Connections 11. 1 Front source selectors volume balance mono mute record selectors 11. 2 Rear in 5 in 6 aux 1 aux 2 Power supply/output option sockets with link and blanking plugs fitted to NAPSC rc5 control in in 1 cd in 2 in 3 tuner tape in 4 a/v signal in 6 (alternative) ground cd phono ch 1 ch 2 aux 2 phono ch 1 ch 2 to power amplifier with internal power supply optional RS232 data port Inputs 1, 2 & 6 ch1 in ch 2 in -ve Inputs 3, 4 & 5 ch1 in ch 2 in -ve ch1 out ch2 out Input 6 (alternative) +ve ch 2 +ve ch1 Note The NAC 282 AUX 2 input is provided with two sockets.

An optional separate NAPSC supply to provide power to the display and control circuits is also available. Diagram 13. 3 illustrates the NAC 202 connected to a Hi-Cap power supply. 12. 1 input socket mapping The input selector buttons select the source input signal to be routed to the power amplifier and the loudspeakers. The NAC 202 has six DIN input sockets and two alternative pairs of Phono sockets. The Phono sockets can be mapped individually to the CD and AUX 2 input buttons in place of the DIN sockets. Input mapping setup is accessed through the NAC 202 program mode. To switch into program mode press and hold prog from the remote handset (in preamplifier mode). Program mode is indicated by a flashing indicator on the volume control. If no function is operated within five minutes of entering program mode the NAC 202 will return to normal mode automatically.
