This operating mode is identical to the Party-Line w/Auto Mix operating mode with the exception that the Auto Mix function is not active. Studio Technologies recommends that in most cases the Auto Mix function be active. But for special applications or test purpose this mode might be appropriate. Refer to the previous section for details on party-line operation.

The overall connection limitation is really the number of supported Dante flows, which in the case of the Model 5422A is 32. (In most cases, a Dante flow will consist of a connection that supports up to four audio channels.)

Dante audio sources. One source serves as the interrupt signal while the second source is considered to be program. The Model 5422A implements IFB (1 Int-in) such that both program with interrupt and program only channels are created. The action of IFB (1 Int-in) is controlled using the audio signal that arrives in the Dante receiver (input) audio channel specified for interrupt.

And for optimal performance, this IFB mode also ensures that detection (“triggering”) will take place independently for each of the three inputs. The Model 5422A implements the IFB (3 Int-in) mode such that both a program with interrupt and program-only output channels are created.
