6.10 CONFIGURATION – ADVANCED
Figure 12: Advanced
The “Advanced”-tab allows users to congure miscellaneous advanced sengs for the MPA1600. This includes AGC and
speech power booster, Alarm and PA/EMPA opons, NORSOK mode, Alarm aenuaon, trimming the end of recorded
messages and alarm synchronisaon meouts.
The sound opons include the AGC (automac gain control) preset and speech power booster to make it easier to under-
stand spoken messages. The AGC can be disabled or set to tuned pre-tuned sengs for the InterM PA-93xx ampliers or the
Phontech 1670/1671 ampliers. It is also possible to set custom AGC sengs, but this requires a thorough understanding of
audio signal processing. The speech power booster is an equaliser preset designed to improve the comprehension of
spoken messages based on the most important frequencies present in speech. This can be enabled if some areas struggle
with understanding spoken messages, at the cost of a smaller dynamic range.
