will be lit in the fifth position.
During Calibration Step 5, you may set the EF1210 to use different AEC Reference
Inputs for each channel. The reference signal used with channel 1 will be used as
Zone A output, and the reference used with channel 8 will be used as Zone B output.
Microphones on the input channels must be placed in the sound field of the appropri-
ate Zone output for the EF1210 to operate correctly; otherwise echoes will not be can-
celled. In other words, if for example the microphone on channel 3 is in the
soundfield of the loudspeaker connected to the Zone B output, channel 3 must be con-
figured to use Reference B (AEC B) as its reference.
Note.
The CODEC output level is also adjustable from -20 dBu to 0 dBu
using the UP and DOWN arrows on EFPanel.
