room and use the same reference, configure the echo canceller reference on one Vor-
tex device and assign it to the EF Bus as the EF Bus Reference. 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 may 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.
P RESETS
After configuring your Vortex device, save your settings to a User Preset (PRESETS
16-47). Also, set the P
OWER ON PRESET to the User Preset you have saved to. The
P
OWER ON PRESET determines how the unit is configured upon power up.
If you have multiple Vortex devices in your system, save to a User Preset on each unit
and set the P
OWER ON PRESET accordingly.
