A single Bolt receiver can only be paired with and receive video from (1) transmitter at a time.
When the pairing process is performed with a second transmitter, the receiver will lose its pairing with the first transmitter and will only link with the second transmitter. See this article for the difference between "pairing" and "linking" on a Bolt.
Since the pairing process must always be performed to associate the Bolt receiver with a different transmitter:
- It is not possible to send video from 2 or more Bolt transmitters to (1) Bolt receiver at the same time.
- It is not possible to rapidly switch (1) Bolt receiver between (2) separate Bolt transmitters.
