2.2. Press the R

ELECT

button to choose which output is being calibrated. A nom-

inal level noise signal is played through the selected Zone output(s).

• When the EF1210 first enters Zone Output calibration, the AEC A and AEC

B LEDs are lit, indicating that both zones will be calibrated. Use this if you

want to calibrate both zones at the same time.

• If you want to calibrate only Zone A, press the R

ELECT

button to select

Zone A. Only the AEC A LED lights, indicating Zone A.

• If you want to calibrate only Zone B, press the R

ELECT

button again to

select Zone B. Only the AEC B LED lights, indicating Zone B.

2.3. Check the specifications of your room audio amplifier input:

• If it expects consumer level (-10 dBV) input, press the L

EVEL

DJUST

OWN

button once.

• If it has a balanced input connector and expects 0 dBu input level, press the

EVEL

DJUST

button once.

More precise level adjustments can be made with the RS-232 commands (see the

GAINZ command on page 68 of the Command Set Reference.

2.4. If you selected only one of the Zone Outputs, repeat for the second Zone Output.

For visual instructions, refer to Figure 12 on page 31.

Check Acoustic Gain.

2.5. At this point you are ready to calibrate the absolute maximum room audio ampli-

fication level. For this step, you should ensure that the microphones have been

returned to their normal operating location and orientation. This procedure uses

a known nominal electrical noise signal level at the zone output to let you see if

any of the microphone input channels will exceed the permissible acoustic gain

during normal conferencing operation. The level of this noise signal is such that

if any microphone input channel registers more than three green LEDs on the

EF1210 I

NPUT

IGNAL

EVEL

ETER

, the acoustic gain limit of that microphone

channel has been reached. This represents the maximum amplification that may

be applied to the room audio. The room audio may be run at any level below this

threshold, but should not be amplified beyond this level unless the acoustic gain

is reduced by some other means (See “Acoustic Gain” on page 44).

All microphones should be checked in this step as verification that no micro-

phone inputs or zone outputs have been miscalibrated.
