Perceived loudness, dynamic range and peak level; suitable for all situations where some combination of these three must be powerfully yet unobtrusively controlled.
BENEFITS:
Brings consistency to all programme
streams without erasing musical dynamics
Ends listener annoyance from over-loud
segments such as commercials and shouting
DJs
Improves audibility and clarity of programme
Eliminates overload distortion and damage
forever
Eliminates the inconvenience of unauthorised
tampering with controls
Maintains programme path reliability
APPLICATIONS:
Control levels of Outside Broadcasts, news
booths, unattended studios and 'remotes'
Overload protection for STL, digital codec, PA
and monitors
Normalisation at Ingest and Master Control
done right!
Sound level control for Television
FM broadcast: Networks, Relay from satellite,
Community Radio & RSLs
