ment” on page 19):
Connect the 8 Mic/Line Inputs to microphones.
Connect the 8 Line Outputs to the inputs of a mixer.
Turn off Phantom Power on automixer.
Connect Zone Output(s) to amplifier(s) or powered loudspeaker(s).
Connect AEC Reference Inputs to the T

ALIBRATION
Calibration of the EF1210 involves a sequence of five calibration steps to configure
the input and output levels of the EF1210 to match those of the equipment to which it
is connected. The EF1210 can be calibrated either from the front panel or by using a
computer. Please refer to “Calibration” on page 27 for more detailed information on
the Calibration procedure. Correct calibration is essential for satisfactory operation of
the EF1210, so please take the time to familiarize yourself with the details of the Cal-
ibration procedure by reading “Calibration” on page 27.
For front panel calibration, enter Calibration mode by pressing and holding the A

Caution!
The EF1210 is designed to maintain a 1/4” (6.35 mm) air circula-
tion clearance above the enclosure. Do not stack or install
EF1210s in such a way as to defeat this clearance, block the side
vent holes, or otherwise impede air circulation around the
EF1210.
