Fader Resource

Fader Resources are used in the AlphaCom System for providing clickfree audio switching between sources in group audio features.

Usage

One fader resource is used when one of the following functions are activated:

• Groupcall (switch between gong tone and microphone, fade in/out when m-key is pressed/released.
• Simplex conference

In a multimodule, one fader is needed in each participant module.

A fader is used along with two timeslots. The audio source is connected to the source timeslot. The fader loops the audio to the distribution timeslot. All listeners listen on the distribution timeslot. When switching sources, the fader fades out the source audio, and keep feeding the distribution timeslot during the switch. The listeners are not involved in the switch.

Fader Resource is a SBI Channel of an Audio Scanner set in Loopback mode.
