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.

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.
