DESCRIPTION
The KB-211 remote speaker station permits the user to select between two channels of
party-line communications, with the ability to talk and/or listen on the selected channel.
The user can listen via the integral speaker, or may use a headset or telephone-style handset –
and can talk via a headset mic, a telephone handset, or a push-to-talk microphone.
The KB-211GM adds a gooseneck-mic connector and VOX
circuitry, for hands-free full-duplex communications without a
headset. A switch allows the user to choose between the optional
GM-9 or GM-18 microphone and the headset connector.
The adjustable-sensitivity, close-in VOX feature automatically
detects the user’s voice at the mic and dips the level of the integral
speaker while increasing the gain of the microphone, performing in
the opposite manner when listening. The potential for acoustic
feedback is minimized while permitting natural conversation levels
and dynamics.
Microprocessor-controlled logic and switching yields a
feature-rich intercom station in a compact format. Electronic
switching for the talk button, with mic-on LED indicator, permits
momentary or latching operation. For call signaling, a bright LED
lights when a call is activated on a connected intercom channel.
A defeatable audible call signal, with level control, is also provided.
Separate level controls are provided for intercom level and for balanced program input.
A local program source may be fed to the station, allowing the user to monitor that source
while remaining in contact on the intercom system. The balanced program input can also
be used in conjunction with the stage-announce output of a main station to provide a
paging interrupt, allowing paging at the KB station even if the intercom volume control is
turned down.
A set of option dip switches is located at the top of the circuit board. Switches are provid-
ed for mic-latch disable (momentary-only talk), long-line operation, channel selection, call
signal tracking, and audible call signaling.
These versatile stations may be wall or console mounted in a standard U.S. 4-gang
electrical box, or may be mounted in the optional V-Box for desktop, surface-mount, or
portable applications.
Either of the stations may be used with the optional 4-wire or TW (two channels on
a single mic cable) daughter boards. With the TW board, the stations become plug-in
compatible with a Clear-Com TW system. The 4-wire board creates separate send and
receive circuits, so that the station may be attached to fiber-optic lines or other audio
routing systems with 4-wire connections.
The stations are powered by the intercom
line or by a local power supply when used
with the optional 4-wire daughter board.
