to achieve correct left/right channel balance.
This is not a balance control like those found in consumer audio products.
This control changes gain of the right channel only. Use this control if the
right analog input to the 8700i is not at exactly the same level as the left
input. Be certain that the imbalance is not from a certain program
source, but only through distribution between the console output and
8700i input. This is best accomplished by playing program material that is
known to be monophonic, or by setting the mixing console into mono
mode (if available).
7. Adjust the Digital Input Reference Level and Right Balance controls.
If you will be using the AES3 digital or Dante audio-over-IP input, set the input as
desired and repeat steps 5 and 6 above using the

8. Enable or Defeat the “Multipath Mitigator” Left/Right Skew Corrector.
See “Multipath Mitigator” Left/Right Phase Skew Correction on page 3-8.
The Phase Corrector controls are found in the active Processing Preset. Because
the Phase Corrector adds about 250 ms of delay to the audio path, if you do not
wish to use it, we recommend defeating it in

control. If you defeat it, this will override the P

con-
trol in the active Processing Preset.
9. Set response to an invalid or missing digital input signal. (optional)
Refer to step 19 on page 2-40
10. Set up and activate the BS.1770 Safety Limiter in the digital radio processing chain
(optional)
The BS.1770 Safety Limiter prevents the BS.1770-3 integrated loudness in the dig-
ital radio processing chain from exceeding a value set by the

control. If your country requires that the integrated loud-
ness of your digital radio broadcast to be constrained according to the BS.1770-3
loudness measurement algorithm, execute the steps below.
If your country does
not require this, leave the BS.1770 Safety Limiter off.
