Using a new synchronization scheme for a multi-channel class-d amplifier

A method of processing a plurality of input signals for a multi-channel class-D amplifier comprising a plurality of class-D amplifier channel modules, wherein the method comprises:

• generating synchronization information;
• providing each class-D amplifier channel module with a corresponding input signal from the plurality of input signals and the synchronization information;
• employing switching frequencies for each class-D amplifier channel module;
• and
• processing the corresponding input signals at each of the class-D amplifier channel modules according to the synchronization information to produce corresponding output signals,
• wherein the synchronization information comprises information for the switching frequencies and processing offsets wherein switching frequencies are substantially similar to one another and the processing of the plurality of input signals is offset in time across the plurality of class-D amplifier channel modules.
