Peak-level limiting
The Max SPL or Bass limit parameter allows 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 Bass 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 Bass limit value is fixed at -11dBFS and
you cannot adjust it.
To complete the speaker setup
You have now completed the first stage of setting up the 568,
and you should save the changes you have made by choosing
Save from the File menu. You can ignore the Distances,
Crossovers, Precision, Phase/Gain, and Connections pages
of settings for the moment; these will allow you to check the
values you have set up when you calibrate the digital surround
processor.
The size value is displayed in the SizeCalc display.
● Type the size into the appropriate field.
If you prefer you can copy and paste the size directly.
Subwoofer filtering and type
For each subwoofer in the system you can specify the
subwoofer filtering, and its type.
● Specify the filtering from the following options:
Option Description
Narrow The digital surround processor
provides a low-pass cut off; the
subwoofer’s crossover should be
bypassed. This is the recommended
option.
Wide The subwoofer includes a crossover.
● Specify the type of subwoofer as Analogue or DSP.
