Specifications

The KB-701 remote speaker station connects to a single channel
of party-line intercom, and operates in half-duplex mode, similar
to a walkie-talkie. It features both an integral speaker and a ush-
mount electret microphone with mic limiter and a push-to-talk
button. The station may be programmed via two internal dip
switches to operate in four dierent modes, activated by other
stations within the intercom system. The dierent operating
modes are activated using the call signaling function of another
station, which allows for individual control of the speaker and
microphone.
Microprocessor-controlled logic and switching yields a feature-
rich intercom station in a compact format. An electronic
momentary-only talk button activates the talk function. Use
the talk button or the reomote control from another station to
activate the mic. A blue-colour LED indicates that the mic is
on, while an amber-color LED indicates the mic is o. Mic
sensitivity is selectable for either close or distant voice pickup.
The KB-701 oers both visual and audible call signaling, gaining
the attention of the user when not at the station. A red-color
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. This would allow paging at the station even if the
intercom volume control is turned down. In addition, the
intercom volume control of the KB-701 can be internally set so
that an incoming message would still be audible, even if the
control was turned all the way down.
The KB-701 may be wall or console
mounted in a standard 4-gang electrical
box, or may be mounted in the optional
V-Box for desktop, surface-mount, or
portable applications. It may be used with
the optional 4-wire or TW (two channels
on a single mic cable) daughter boards.
The station is powered by the intercom
line or by a local power supply when used
with the optional 4-Wire daughter board.
