Amplifier system having prioritized connections between inputs and outputs

An amplifier system, comprising:

• a plurality of input terminals;
• a plurality of amplifier channels;
• switching means for selectably connecting each of the plurality of input terminals to each of the plurality of amplifier channels;
• and
• control means for controlling the output level of each of the amplifier channels in accordance with the input terminal that is connected to the amplifier channel.

An amplifier circuit, comprising:

• a plurality of input terminals;
• a crosspoint switch having a plurality of inputs and outputs, each of the input terminals being connected to an input on the crosspoint switch, the crosspoint switch being able to connect each of its inputs to each of its outputs;
• an attenuator connected to each output of the crosspoint switch;
• an amplifier circuit connected to an output of each attenuator;
• a microcontroller that controls the operation of the crosspoint switch wherein the microcontroller receives inputs from the plurality of input terminals so that it can determine which input terminals have an active audio signal, wherein the microcontroller maintains a table indicative of the priority each input terminal has on each amplifier circuit and wherein the microcontroller connects input terminals with active audio signals to the amplifier circuits in accordance with the priority table.
