Using peak-level limiting
The Max SPL or Limit parameters allow you to set up peak-level
limiting for bass signals, and the setting applies to all the
discrete digital DSP presets.
If your loudspeaker layout includes one or more subwoofers the
parameter is named Max SPL, and it sets the peak-level limit for
the LFE channel.
If your loudspeaker layout contains no subwoofer the parameter
is named Limit, and it sets the peak-level limit of the bass signal
added to the main loudspeakers. For loudspeaker layouts using
Meridian DSP loudspeakers as the main left and right, or centre
speakers, the Limit value is fixed at -11dBFS and the parameter
does not appear in the menu.
