Subbus

The AP400 is equipped with one internal sub-mix bus. The subbus is a matrix output which allows signals to be mixed and level controlled. The subbus is then made available as an input to the matrix for further signal routing.

See page 7 for a description of this submenu.

EC reference and PA

The EC reference tells the microphones which output will be used as the sample reference for echo cancellation. EC REF references Output D (typically used for connection to an external amp speaker). A unit will support one common EC reference for all four microphones (as shown in Figure 2.21). Note that the PA output follows the settings for the EC Ref. This is because any audio being sent to a speaker must be used as EC Ref for Echo Cancellation to work properly.
