Abstract:
1. A multi-channel amplifier comprising: a plurality of inputs each configured to receive an input signal; a plurality of outputs; an amplifier stage comprising a plurality of amplifier channels connectable with respective inputs and respective outputs, each amplifier channel having a maximum channel power that can be emitted by that amplifier channel, each amplifier channel being connectable to at least one of said inputs and at least one of said outputs and amplifying the respective input signal for said at least one of said inputs to produce an amplified output signal at said at least one of said outputs; and an adjustment device associated with said amplification stage, said adjustment device, for each of said amplifier channels, dynamically setting a limit power for amplification of the output signal emitted by that amplifier channel, said limit power being set a maximum value for each of said outputs, and said adjustment device being operable to cause a sum of the respective limit powers for all of said outputs to be simultaneously emitted independent of respective settings of said limit powers, with said sum of said limit powers always being smaller than a sum of said maximum values of all of said outputs.
