Assembling

The outdoor microphone Nor1218 is normally shipped 
without preamplifier and microphone, since these 
parts is normally shipped with the Sound Level Meter 
Nor131 or Nor139.

 Depending on the application, you will need a mast 

or tripod for mounting the microphone system and 
possibly devices for proper grounding and lightning 
protection, see below.

We recommend cable type Nor4531, which comes 

in standard lengths of 5, 10, 15, 30 and 50 metres – 
other lengths are available on request. 

Unscrew and remove the upper part consisting of 

birdspike and windscreen as one unit. Do not remove 
the windscreen from this upper part as this may de-
stroy the weather protection and alter the acoustic per-
formance.

 The unit is delivered with an adaptor for mounting 

on a tripod. The cable is led through a slot in the side of 
the adaptor. The base screw has a threaded hole like 
those commonly used for cameras (3/8” UNC). The 
base screw also forms a tension relief for the cable. 

Remove the base screw and slide the cable through 

the base unit. Assemble the microphone cartridge to 
the preamplifier and connect the preamplifier to the 
cable. We recommend mounting the supplied O-ring 
between the microphone cartridge and the preamp-
lifier.
