MIC INPUT
The LM-2 is an active input module with one microphone and
one stereo line input, which allows a microphone and a line
level audio source - such as a DJ mixer, laptop, MP3 player or
similar - to be connected to the 46-80 at a remote location.
The module also includes the functions of the RSL-6 Remote
Control Plate (see page 9), permitting control of zone music
level and source. A music ducking button activates the
46-80’s priority circuitry; when enabled, a microphone signal
from the LM-2 will reduce the music level in the zone. The
LM-2 connects to the 46-80’s FACILITY PORT, and thus will
generally be installed within Zone 1.

PM Series microphones
Cloud PM Series paging microphones may be connected
directly to the 46-80 using the DIGITAL PAGE MIC port using
Cat 5 cable. PM models are available for paging to 4, 8, 12
or 16 zones, and also to 4 or 8 zones with storage for builtin spot announcements. As the 46-80 only supports four
zones, not all zones available from the PM8, PM12 or PM16
can be accommodated by a single 46-80; the PM4 and
PM4-SA (4-zone) models are most likely to be useful.
The Cloud PM1 paging microphone is also compatible with
the 46-80. It is a much simpler unit which addresses a single
zone (although zones may be paralleled for wider access).
