Comtek BST 75-216 CW Mini Base Station Transmitter with 10 Wide Band Channels (216 MHz)

Synthesized Base Station Transmitter with Companded and Non-Companded Channels

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.

The BST 75-216 is available with three different EQ setting options:

BST 75-216 P = Pro Audio EQ with all 10 channels using the wide band compounded channels for use with the PR-216 receiver only. Offers extended low end frequency response.

BST 75-216 CW = Communication version with all 10 channels using the wide band compounded channels with the standard EQ. For use with the PR-216 receiver only.

BST 75-216 CWN = Communication version with 5 channels using the wide band compounded channels for use with the PR-216 receiver and 5 channels using the narrow band non-companded channels for use with the Phonak Invisity receivers. Both channel groups use the standard EQ.
