Setting Range OFF (default), 1, 2, 3, 4, 5)
• 1 Peak Limiter 1 (
speech applications)
This protects amplifiers and speakers
against damage caused by an excessive
signal input.
• 2 Peak Limiter 2 (
musical applications)
This protects amplifiers and speakers
against damage caused by an excessive
signal input.
• 3 Sonic Normalizer (
BGM reproduction)
Equalizes the volume of Background Music
by boosting quieter sounds and lowering
louder sounds, making overall volume more
uniform.
• 4 Leveler 1
(Speech applications) Makes
paging calls easier to hear by equalizing
the difference in speech signal volume that
may result from individual differences in speaker voice volumes or variations in speaker-to-
microphone distances.
