Centre

Use the Centre drop-down menus to specify which presets use the centre speaker, and its size and type.

●From the first drop-down menu choose one of the following options:

Option	Description
None	If you do not have a centre speaker.
Movies only	If you want to use the centre speaker for
	Logic and 5.1 Movie DSP presets only.
Movies and music	If you want to use the centre speaker for
	all presets.

●From the second drop-down menu specify the type of the centre speaker; the options are as for the main speakers.

Surrounds

Use the Surrounds drop-down menus to specify the number and type of the surround speakers.

●From the first drop-down menu specify the number of rear speakers and side speakers you have in your surround system.

●Use the Sides and Rears drop-down menus to specify the type of the rear and side speakers.

Subwoofers

●Use the Subwoofers drop-down menus to specify the number of subwoofers, and the DSP presets that use them.

If your main left and right speakers are small you will need to use one or more subwoofers to handle the bass. You can choose between appropriate combinations of mono (front), centre, left and right, or surround.

If your main left and right speakers are large you can use one or more subwoofers to augment the bass from the centre channel. With 5.1 sources an additional option is to use the subwoofer only for the LFE channel.

You can specify a different subwoofer configuration for Music, Logic, and 5.1 Movie DSP presets.

The Advanced checkbox is for dealer use only, and it is recommended that you leave this unchecked unless you have special requirements.
