Assembling
The outdoor microphone Nor1216 is shipped fully as-
sembled. However, in order to mount the microphone
cable the unit has to be opened.
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 Nor1408A, which
comes in standard lengths of 5, 10, 15, 20, 30 and 50
metres – other lengths are available on request. This
cable is Teflon®-insulated and hence absorbs very lit-
tle water, which is important to retain high insulation in
all weather conditions. The mantle is made of polyure-
thane to ensure a robust cable, yet flexible at low tem-
peratures. If you need weather-protected connectors,
we recommend cable type Nor1485.
Unscrew and remove the upper part of the microphone
consisting of birdspike and windscreen as one unit.
Do not remove the windscreen from this upper part as
this may destroy the weather protection and alter the
acoustic performance.
Pull up the assembly of microphone cartridge and
preamplifier: See picture on this page. This assembly
is mounted to the base unit by the friction of an O-ring
and may be pulled straight up.
If the microphone is to be mounted on a mast,
mount the base unit and let the microphone cable
go through the base unit. Connect the cable to the
