Broadcast auxiliary service
From Wikipedia, the free encyclopedia
A broadcast auxiliary service or BAS is any radio frequency system used by a radio station or TV station, which is not part of its direct broadcast to listeners or viewers. These are essentially internal-use channels not intended for actual reception by the public, but required to get those signals to such a transmitter.
Examples include:
- studio-transmitter link (STL)
- transmitter-studio link (TSL)
- remote pickup unit (RPU)
- electronic news gathering (ENG)
