Where are the MTRs normalled to in the API Legacy Plus?

The correct answer is that the MTRs are normalled to MTR 90 1-24 in the API Legacy Plus. This is significant because the MTR (Multi-Track Recorder) 90 series specifically comprises 24-track recorders that are common in professional audio environments. The normalled configuration allows for seamless routing of audio signals, making it easier to manage sound sources and facilitate a smooth workflow during recording and mixing sessions.

The normal settings in the API Legacy Plus are designed to make optimal use of the MTR 90's capabilities. When connections are normalled to MTR 90 1-24, it indicates that these tracks are pre-routed within the console's structure, allowing audio engineers to quickly access and manipulate tracks without needing to establish new patching for every session.

Other choices refer to different configurations or recorders that do not align with the normal routing scheme established by the API Legacy Plus. MTR 1-16 suggests an earlier system with fewer tracks, while Pro Tools typically signifies a digital workstation environment and its channels outside of the specific normalled routings found in the API Legacy Plus. MTR 90 25-48 would imply a different set of tracks that are not used as the default normal
