This article describes how to connect an external amplifier to the line output of the IP substation.

Amplified calling - amplifier constantly on

The power amplifier is controlled through input 1 and 2. By strapping one can make the amplifier constanly on:

No programming is required.

Note: When the amplifier is constanly on some humming might be heard in the speaker in idle.

Amplified calling - amplifier controlled by M-key

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.

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 to control the IP substation relay

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.

-The [[WK20 - 20W Power Amplifier|amplifier 1000614100]] is very well suited to amplify the audio of a Stentofon station. The amplifier can be used standalone (speaker only), or it can be used in combination with a station to amplify the speaker signal. It can be used both with IP stations and with analog stations.
