Meridian Audio 568 manual Using peak-level limiting

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.
