INPUT>SOURCE AUDIO MENU
Note:
To monitor input audio before Auto Balance, be sure to monitor at the Program Input or A/B
Loudness Matched patch point. To monitor audio immediately after Auto Balance, choose the
Pre-Declipper patch point.
♦
Enabling
Auto Balance
(as indicated by the yellow checkmark) turns the feature on and off. The current
amount of correction is displayed just below this control. Positive values indicate that the right channel
gain is being increased, while negative values indicate an increase in left channel gain.
♦
The
Range
slider sets the maximum total amount of gain that can be increased or decreased in each
channel. For example, with the Range control set at 6.0dB, the gain in each channel can be boosted by
up to 3dB and attenuated by up to 3dB. Each channel contains an ITU BS-1770 loudness monitor which
measures and compares the frequency-shaped RMS level in each channel.
♦
The
Integration
Time
control determines how quickly Auto Balance corrects any discrepancies between
the left and right channel. Shorter integration times correct channel-to-channel imbalances more quickly
and provide more consistent levels between the left and right channels. Reducing the integration time too
much may cause an undesirable or unnatural effect as the channels re-balance, and therefore the default
setting of 10 seconds is recommended for most situations.
♦
The
Channel
Loss
Timeout
option automatically fades to mono if one input channel is missing. The
length of time Omnia.7 waits before fading to mono can be set to 3, 10, 30, or 60 seconds. 10 seconds is
the default. This feature can be disabled altogether by selecting “Off”.
