NAC-N 172 XS Installation and Connection
2.2 Mains Power Connection
Connect the NAC-N 172 XS to a mains power socket using
either the mains cable supplied or a Naim Power-Line.
2.3 FM/DAB Aerial Connection
The optional NAC-N 172 XS FM/DAB module will only be
able to provide high quality FM and DAB radio if a strong,
interference-free radio signal is available. The
NAC-N 172 XS rear panel FM/DAB Aerial socket must
be connected, via 75 Ohm low-loss coaxial cable, to a
suitable aerial. The aerial should be mounted clear of large
obstructions and as high as possible; ideally on a roof.
Note:
Your local retailer should be able to offer advice on
a suitable aerial and aerial installer.
