Vortex Media VTX 1000 - Manual (Page 49)

EFBus
The default routing of the EFBus will be sufficient for our design. However, for clarity, the labels have been
changed to reflect the signals that are placed onto the bus and all unneeded cross-points have been muted.
Since the Vortex EF2280 uses the W and Y buses to send microphone, codec, and program audio to the
Vortex EF2241 and the ID of the Vortex EF2280 is 00, the audio signals WB0 and YB0 need to be routed to
Inputs WM0 and YM0 of the Vortex EF2280. Remember that the signals that a unit places onto the EFBus
is put into a placeholder where that placeholder is identified by the device ID of the unit that put the audio
signal into this placeholder. Here, the Vortex EF2280 placed audio onto the W and Y buses and since the
unit has a device ID of 00, the placeholder is identified as WB0 and YB0 where the "B" stands for bus. The
Vortex EF2241 takes that signal from the bus and internally assigns that signal to one of three mixes for the
W Bus (WM0, WM1, or WM2) and one of three mixes for the Y Bus (YM0, YM1, or YM2) where the "M"
stands for mix. By default, WM0 and YM0 are routed to Output T of the matrix mixer, so we will keep that
default routing and use the WM0 and YM0 mixes for this example.
