The 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 multifunction RF indicator detects bad antenna load, RF presence, coaxial cable short or open condition for quick and easy troubleshooting.
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 FM 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 for stand-alone portable applications.
