Figure 64 Cumulative Frequency Boost/Cut
Figure 64 shows the result of having the gain set on more than one channel simultaneously. The
blue traces show each band (lowest cut-off/centre frequency) with ±12dB gain. The red traces show
the cumulative effect of all bands with +12dB gain and all bands -12dB gain, with EqxBW=0 for the
peak filters.
