Equipment Placement
If the BST 75-216 base station is to be rack mounted, a remote antenna
must be used. The base station should be mounted away from equipment
that uses large power transformers to reduce 60 Hz hum possibilities.
Special Note:
When using the base station in close proximity to other
audio equipment, ensure that the audio equipment is not susceptible to
RF interference. This can be accomplished by temporarily installing
the base station, and then while the base station is operating, checking
all audio outputs for uncharacteristic noise. If a problem is found,
move the base station or the remote antenna as far as possible from the
affected equipment. Should you continue to have problems, contact
COMTEK’s Technical Support Services for assistance.
Power Requirements
The BST 75-216 base station is designed to be powered by 12 volts DC.
The standard barrel type power jack (5.5mm X 2.1mm) is nonpolar and
will accept either ± 12 volt DC on the center pin. The switching power
supply adaptor which is included is
a universal input type that will
accept 100-240 volt, 47-63 Hz
(AP-12V1-75). The on/off switch
on the front panel of the base
station transmitter should be
turned to the “off” position
when the power plug is
initially plugged into the
transmitter.
