Appendix A: AEROMAX DRC Presets
Fine Arts 5B Gen
Fine Arts 5-Band General offers medium processing appropriate for artistic
programming that may have large dynamic range variations. It produces consistent
loudness and spectral balance.
ITU 5B Loudness Lim
ITU 5-Band Loudness Limit utilizes a specially tuned Multiband AGC Limiter and the
Final Limiter to slowly adjust the average program loudness to a specific loudness
value as measured over time. The Multiband Limiters and Final Limiters act until the
very slowly responding wideband AGC catches up. The multiband AGC is bypassed
(1:1) so spectral balance is unaffected. This preset can be appropriate for ingest,
live, or network transmission applications where content is pre-normalized.
Music 5B Hvy
Music 5-Band Heavy is an aggressive preset for TV music channels that effectively
delivers music programming to small televisions and portable receivers.
MVPD 5B Gen
MVPD 5B Gen is intended for Multiple Video Program Distributors who may not
have full control of all programs, interstitials or commercials present in a given
network stream. It applies medium-light multiband processing, sets Gate and Freeze
to prevent background noise pull-up, and is tuned for all genres.
Net 5B Limit
Net 5B Limit applies a final polish to an already consistent network program prior to
distribution. A combination of TV 5B Light and ITU 5B Loudness Limit, this preset
has a very slow input AGC, and a lighter multiband AGC. It preserves microdynamics
