The COMTEK BST 75-216 is a versatile and innovative transmitter that is simple to use, yet comes with 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.

BST 75-216P is the Pro Audio EQ option. All 10 channels use the wide-band companded channels in the 216 MHz band for use with PR-216 receiver only. It offers extended low-end frequency response.
