B routes the signal from the Channel B send bus to the monitor.

A B routes both channel send busses to the monitor.

(OFF) disconnects the send signal from the monitor.

The two Monitor RECEIVE routing switches (MONITOR 1 RECEIVE, MONITOR 2 RECEIVE) do the same thing, only with the signal from the A and B Receive Decoders.

But these are stereo monitor mixers, and the individual send busses or receive channels may be mono or part of a stereo pair. So we’ve given you a lot of flexibility in how the signals are panned in the monitor circuits.

About Monitor Panning

Since ZephyrExpress’ mixers are digitally controlled, we were able to build in a lot of versatility.

Each of the four possible sources (A and B send bus, A and B receive codec output) is connected to four separate pan controls for each monitor mixer. Each control can be set to any position in the left/right field. (The controls themselves appear in the Audio menu, and are discussed below.) ZephyrExpress will use the one control that matches that source’s routing switch:

If you select A on the routing switch, the submenu’s A setting will be used.

If you select B on the routing switch, the submenu’s B setting will be used.

If you select AB , the mixer will use the submenu’s AB setting A position for the A channel and the AB setting B position for the B channel.

The drawing that follows describes what the software’s actually doing. Assume that the hidden “Monitor 1 Receive” block is identical to the Send block you can see. By the way, this is all repeated for the MONITOR 2 circuit... making a total of 16 pan pots in ZephyrExpress.
