Output limiter
The limiter on each output has adjustable attack and threshold, with a
release time that is selectable to be a multiplier of the attack time. For example,
as shown below, the attack time is 2mS and release is “x16” so 32mS. The
attack and release times can be automatically linked to the high pass filter
frequency, so that they are set to correct values for the output's frequency
range. If this feature is enabled, the display will show ’Automatic T/C’ in place
of the attack and release times. Selection of automatic time constants is
through the ’Design a Crossover’ wizard, in the ’Crossover Sub-menu’.
Output “D-Max” (Clip) limiter
The clip limiter on each output is designed to sit at a threshold just above
the standard limiter and has a look ahead attack so that its threshold can never
be exceeded. The release time can be automatically linked to the high pass filter
frequency, so that it is set to a value appropriate for the output's frequency
range. If this feature is enabled, the display will show ‘Rel.=Auto’ in place of
the release time. Selection of automatic time constants is through the ‘Design
a Crossover’ wizard, in the ‘Crossover Sub-menu’.
More information about the limiters and their use is given in the section on
page 22.
Information:
Note that 2 bands each will be lost when using 48dB slope crossover filters, resulting in
a maximum of 5 bands of EQ when both high and low pass are set to 48dB/Octave.
