Review what inputs need to be included in your echo canceller reference —
See "Build Your Echo Canceller Reference" on page 31. Remember that each
microphone needs to have an echo canceller reference. If all microphones are
in the same room and use the same reference, configure the echo canceller
reference on one Vortex device and assign it to the EF Bus as the EF Bus Ref-
erence. Only one Vortex device out of multiple units linked together can put
an echo canceller reference on the EF Bus. For each additional unit, assign
the echo canceller reference to use the EF Bus Reference.
For systems with more than one room, you will need to use the W, X, Y, or Z
sub-busses to share the echo canceller reference in your additional rooms if
the EF Bus Reference has already been assigned to the EF Bus.
After configuring your Vortex device, save your settings to a User Preset (P
