This versatile and innovative transmitter is simple to use, yet it has sophisticated features such as “Flash Memory” synthesized channel programmability with a manual, 10-channel selectable switch.  A unique multi-function RF indicator detects bad antenna load, RF presence, and coaxial cable open condition for quick and easy troubleshooting.  To accommodate a greater variety of receivers, the BST 75-216 can operate with non-companded receivers or with companded receivers for higher fidelity sound reproduction. A practical, compact, all-metal enclosure is suitable for permanent rack-mount installations or for stand-alone portable use.
