I. GENERAL.
1-1. GENERAL DESCRIPTION.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any
interference received, including interference that
may cause undesired operation.
The Model AR2000-M (see figure 1-1) Audio
Router, is a UL listed and cUL certified central
control device that is capable of routing a selected
audio input to specific zones. It can control signals to
speakers designed for 25Vrms line operation or
70Vrms line operation. It can also control 1Vrms
signals intended to be amplified with a separate
amplification device. The AR2000-M has a public
address (PA) function so voice messages or instruc-
tions can be announced over the Audio Router system
through an optional Model MSB-1 or MNC-1 Micro-
phone. The unit can also be used to play background
music generated from an external source over the
Audio Router system.
The Model AR2000-M is an audio multiplexing
device. It is capable of handling two inputs from any
of three different selected source voltages of 1, 25 or
70 volts. The unit has 8 selectable zones which either
the A or the B source is routed to. There is an all call
button that selects all zones. There are also 8 pro-
grammable presets on the unit. The presets are
initiated by the front panel buttons or by remote
contacts wired to the back panel. The front panel
also has a monitor speaker jack. A microphone jack
is also available for use with a MSB-1. The micro-
phone has priority over the two user supplied
sources. The telephone feature is protected by an 8
key password. Options available allow changing the
password and recording a message for broadcasting.
Commands entered via the telephone key pad allow
the user to send a message to specified zones. The
microphone and the telephone interface have the
same priority. If the microphone is in use, the tele-
phone interface is disabled. If the phone message
system is in use, the microphone is disabled.
If more than eight zones or eight presets are
needed by the user, a separate AR2000-Z (See Figure
1-2), zone unit, or AR2000-P (See Figure 1-3), preset
unit is available. Each AR2000-Z or AR2000-P unit
will add an additional eight zone or preset controls
respectively. Up to seven additional Preset or Zone
units may be added for a total of 64 zones and 64
presets.
The Model MNC-1 microphone is a hand held,
noise canceling microphone that is ideal for use as a
local microphone. The Model MSB-1 microphone (See
Figure 1-4) is a base station type microphone de-
signed for desktop operation.
The Model AR2000-M may be installed in indoor
installations only as a rack mounted device.
The Model AR2000-M is a rack mount unit that
will fit any standard 19" rack mount cabinet. The
Model AR2000-M can be used for a variety of priori-
tized signaling purposes, such as playing background
music, paging, start and dismissal, phone messaging
and other communication applications. Additional
advantages of the Model AR2000-M include economi-
cal system expansion and long term system flexibil-
ity.
The Model AR2000-M routes audio signals and
applies them through zone outputs to the devices in
the system. The AR2000-M connects easily with
