GENERAL DESCRIPTION
The BS 217 (19”/1RU) is designed to be a dual
channel master station in an ASL intercom
system. For the connection to remote stations,
use professional microphone cable.
The built-in dual channel power supply can
safely drive up to 15 Basic Series beltpacks
operating at full power. The power supply is
fully protected against wiring mistakes (reverse
power), short circuit or excessive thermal
condition. Should one of these conditions
occur, the unit shuts down. Once the fault
condition has been removed, the unit resets
automatically and full power is restored.
Each channel has a Volume (listen level)
control, a TALK and a CALL LEDs.
With a headset connected to the XLR-4
headset connector one can talk and listen to
each channel separately or to both channels
simultaneously.
There are side tone trimmers to adjust the listen
level of one’s voice in one’s headset.
The unique ASL Call system provides both a
flashing red LED and a very distinctive sound
signal. A slight touch of the CALL button makes
the call LED flash, whilst holding the button for
2 seconds the call sound signal is activated.
An Aux input connector with Ground Lift switch
at the rear panel allows injecting an external
line level audio signal into the intercom lines.
Special attention has been paid to the
intelligibility of speech. By applying low
noise/high speed circuitry, a speech presence
filter and a specially designed headphone
amplifier, communication is very comfortable
even in environments with high background
noise levels.

MAINS POWER & SAFETY EARTH
Connecting to mains power
The BS 217 may be connected to a mains
power outlet which provides 100 – 240 V AC,
50-60 Hz and at least 60 watts. The outlet
should have a clean earth. Avoid using mains
power outlets which also power dimmer
controlled lighting equipment.
The wires in the mains lead are color coded:
green/yellow: Earth / safety ground
blue:
Neutral
brown:
Live
In case the wires in the mains lead do not
correspond with the markings identifying the
terminals in the mains plug, proceed as follows:
•
The wire which is colored green/yellow
must be connected to the terminal in the
plug which is marked with the letter “E”,
or by the ground symbol, or is colored
green.
•
The wire which is colored blue must be
connected to the terminal which is
marked with the letter “N” or colored
black.
•
The wire which is colored brown must
be connected to the terminal which is
marked with the letter “L” or colored red.
Safety Earth
For personal safety and proper functioning
of the BS 217 and its remote stations, the
green/yellow wire of the mains lead must
always be connected to the electrical
installation safety earth or ground
.
The green/yellow wire is in the BS 217
connected to all exposed metal surfaces. Any
rack framework into which this unit might be
mounted is assumed to be connected to the
same grounding circuit.
