Review what inputs need to be included in your echo canceller reference — See
"Build Your Echo Canceller Reference" on page 17. Remember that each micro-
phone 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
EF2280 and assign it to the EF Bus as the EF Bus Reference. Only one EF2280 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 Refer-
ence.
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.
