Note: When the amplifier is constanly on some humming might be heard in the speaker in idle.
Amplifier controlled by relay
The amplifier can be switched on and off by the relay in the IP substation. The relay is controlled by the RCO command in the Event Handler.
How to configure the relay operation:
- In Exchange & System -> RCO, map a free RCO to the relay of the station.
- In Users & Stations select the IP station in the list box, and press the button 'Events'. 'Insert' a new event with the following attributes:
| Event Owner: | The IP station |
| Event type: | 1 - Audio |
| Subevent: | 126 (Press 'Details' to select which types of audio. 126 means all types of audio) |
| When change to: | ON or OFF |
| When related to: | (not used) |
| Action: | RCO 10 |
RCO 10 is used as an example. Use the RCO number you have assigned to the IP substation relay.
