he BST-75 mini base station transmitter meets the highest
professional standards while offering outstanding value
and the most advanced technology available. This versatile and
innovative transmitter is simple to use, yet it has sophisticated
features such as “Flash Memory” 98-channel programmability
with synthesized manual 10-channel selectable user-switch. Plus
a unique multi-function R.F. indicator detects bad antenna load, RF
presence, coaxial cable short or open condition for quick and easy
trouble-shooting.
The compact design of this transmitter is ideal for multiple transmitter
installations. Up to four transmitters can be installed in one rack
space. Also, it operates in the 72-76 MHz band under FCC Regulation
Part 90. This allows a greater RF power capability (120 mW) for greater
range and reliability than customary FCC Part 15 systems.
The audio processing circuit produces full fidelity frequency response
from 80 Hz to 10 kHz with very low residual F.M. noise and distortion.
To accommodate a greater variety of receivers, the BST-75 can operate
with non-companded receivers or with companded receivers for higher
fidelity sound reproduction with a signal-to-noise ratio of up to 100 dB.
All this is designed into a stylish, compact, all-metal enclosure suitable
for permanent rack-mount installations or can be battery powered for
stand-alone portable applications.
