    9 Clip limiter DESCRIPTION When the audio signal drives the amp 's output circuit beyond its power capability , the amp clips and flattens the peaks of the waveform. The clip limiter detects this and quickly reduces the gain to minimize the amount of overdrive. T o preserve as much of the program dynamics as possible, limiting occurs only duri ...

  • QSC Audio PL230 - page 10

    Input filter DESCRIPTION The low-frequency (LF) filter rolls off signals below either 30 Hz or 50 Hz. This improves bass performance by limiting sub-audio cone motion, making more power available for the speaker's rated frequency range. The filter settings for each channel are controlled individually through the DIP switch settings shown. When ...
