In the example below (see figure 45), input 1 is sent to the virtual bus send by muting all four signals on the input 1 primary mix-points. The virtual bus now serves as additional signal processing for the input. The signal routes over virtual bus A and through the signal chain before being sent to the virtual bus return mix‑point and output 1.

This configuration is useful when more than one input requires identical processing. For example if all inputs were normalized but required a uniform gain to bring them up to adequate output levels, rather than changing each pre-mix gain control by a similar amount, all six inputs can be routed to virtual bus A. Then, using the virtual bus A return gain control, a single adjustment can apply the same gain to all six inputs before sending the signal to the desired output line.

In other cases, if multiple microphone inputs are being mixed with program material, only the program material might require loudness contouring. The microphones can be routed directly to the output while the program material input is routed to the virtual bus return where loudness contouring can be applied. The program material is then routed to the same output as the microphones.
