This is the default PA function for sending audio from an access panel to a zone.
The microphone on the access panel is used as source.

 Live speech cannot be used on the Control Inputs of the amplifiers

Configuration

 By default, Live Speech is pre configured on the PTT key of the ECPIR-x access panels. For access panels EAPII-x og EAPFX-x, Live Speech is preconfigured on the PTT key of their respective external microphones when these are connected. By default, the parameters press_action is pre configured to Start Live Speech and release_action is pre configured to Stop Live Speech.

Use Cases:

Case 1: Normal Live Speech on PTT

When a new access panel is added to a project they will have live speech already preconfigured on the PTT key. This is set up without zones and with priority 21.

Adding a zone select key on a different DAK key will allow this function to be used.

Case 2: Live Speech with Handheld Microphone

Setting the live speech function to Wait for PTT will allow a handheld microphone to be used. Triggering the function will prime the access panel, and the next press on the handheld microphone will start the audio.

Availability

This function is available from Exigo 1.0 and newer.
