Paging Input Details
The RM350D is oftentimes installed in re-
tail locations for supplying background
music alone, but it has a full-featured mi-
crophone paging input that makes it ideal
for more demanding installations. The mi-
crophone input is a low-impedance bal-
anced input that works with dynamic
microphones. Whenever a page is made,
the background music is muted. This can
be done in two ways: 1) audio activity on
the MIC input, or 2) a switch contact clo-
sure. For enhanced flexibility, the RM350D
can be set to respond to either a normally
open or normally closed switch contact.
The DDU250 and MBS1000A (see page 58)
are perfect desktop microphones for this
application since they each have a push-to-
talk function.
By using a WMT1A matching transformer,
the MIC input can be connected to the
paging port of a telephone system. The
audio-activated mute function of the
RM350D will cause the background music
to mute whenever a page is made. In ad-
dition, this input also has automatic level
control (ALC), which controls how loud a
page can be and ensures that people with
loud voices don’t boom over the paging
system.
Music-On-Hold Source
The RM350D lets you make the most of
your paging/background music system. A
Pre-Page output connector on the rear of
the unit supplies only the background
music without any of the paging an-
nouncements. Connect this output to the
telephone system’s music-on-hold input
and callers will enjoy the background
music too. The Pre-Page output will sup-
ply either the tuner or AUX
program material depending on the
setting of the AUX/Tuner button.
Speaker Zones
Built into the RM350D is a convenient 4-
zone selector switch group. These push-
on/push-off switches allow you
to control how paging is distributed
throughout a facility. Simply turn on and
off groups of speakers as needs
change.
An “ALL” button is also provided
to turn
on all system speakers, over riding any in-
dividual setting.

Accessories
The RM350D is a unique self-contained paging system with an AM/FM tuner, providing
35 watts of paging power. A low-impedance, balanced microphone input is provided for
microphone paging announcements or telephone paging when used with an accessory
transformer (WMT1A). A music-only output can feed announcement-free background
music to other equipment or to a telephone music-on-hold inpu
t.
