Dialnorm EnB: Using an ITU loudness meter (Linear Acoustic LAMBDA, LQ-1000
or equivalent), set the transmitted dialnorm value here. Note that the factory default
preset of TV 5B Gen is pre-adjusted to produce -24 on average with typical program
audio inputs so the default setting is -24. This should be measured as part of initial sys-
tem setup. The actual value does not matter as long as it matches the measurement.
NOTE: To correctly set dialnorm, the loudness of the output audio must be verified us-
ing an ITU meter. For compliance, any value between -1 and -31 could be val-
id, as long as it matches the actual measured audio. Default is -24.
