an optional Model MSB-1 or MNC-1 Microphone. 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 eight selectable zones to which either the A or the B
source is routed.
There is an All Call button that selects all zones.
There are also eight programmable 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 microphone has
priority over the two user-supplied sources.
The Model MNC-1 microphone is a handheld, noise
canceling microphone that is ideal for use as a local
microphone. The Model MSB-1 microphone (See Figure 5)
is a base station type microphone designed 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 prioritized signaling purposes,
such as playing background music, paging, start, and
dismissal. Additional advantages of the Model AR2000-M
include economical system expansion and long-term
system flexibility.
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 Selectone ® amplified
speakers. A Model AM25CK or AM70CK Connector Kit
is required in each Selectone device to connect it to the
signal line. The Audio Router device supplies 15 W at
either 25 V
or 70 V

supplied to obtain higher wattage levels. Care must be
taken to ensure that the total line impedance of all the
connected devices does not cause the line voltage to
drop.
Each preset can be manually activated locally with its
associated button on the front panel or with a contact
closure at the associated preset control input on the
back panel. When a preset is activated, either locally
or remotely, its associated front panel button LED
illuminates to indicate that the preset has been activated.
The LED remains lit until the preset is deactivated or the
remote contact closure is removed. As an added feature,
when a preset is remotely activated, the associated LED
illuminates and flashes until the remote contact closure is

. An additional amplifier must be
removed. All AR2000-M controls are located on the front
panel except gain adjustments, which are made on the
back panel during installation.
