Clean Feed Structure

This section gives you an overview of the clean feed structure in Series 52 systems and the basic clean feed settings of the TB8.

Besides the program busses and auxiliary busses, clean feeds can be created. These clean feeds could be used as return lines for telephones and OB vans. The signals of these clean feeds can also be used in a preliminary talk matrix. To create a n-1 return line for an incoming signal, you have to activate the Clean Feed check box of the desired fader channel (see Fader Channels). This automatically creates a clean feed that can be found at Mixing Functions. As it is known from PGM busses and AUX busses, you can set the properties of the clean feed busses in this area of the TB8, too.

The following picture shows an example with two connected phones, each with an own n-1 return line. Depending on the selected mode, the signal of the clean feed or the signal of the preliminary talk matrix is sent on the return line. Additionally, at <Device>/<Mixer>, on the Mixing Functions tab talk sources can be defined. These sources are able to speak into the available busses. Two global sources for all busses can be configured. If you want to use more talk sources, this can be implemented with the aid of output functions.

Basic clean feed structure.

In the following the structure and the options of clean feeds are explained more detailed.

Options of clean feed.

The clean feed is created from the program bus with the lowest number the corresponding input signal of the clean feed is currently assigned to.

Example

A telephone channel is connected to program bus 1, 2 and 3. Hence, its clean feed signal is created from program bus 1. If the same channel is only connected to program bus 2 and 3 and not to 1, its clean feed signal is created from program bus 2.

All functions of the clean feed are optional and need not to be configured if it is not necessary to provide these functions to the user:
