Claim 15:
16. A sound system comprising:
a sound source having an analogue audio signal output for outputting an audio signal and a sound volume control;
a signal amplifier apparatus comprising:
an analogue signal input configured to be coupled to the analogue audio signal output of the sound source;
an analogue signal output;
an amplifier module coupled between the analogue signal input and the analogue signal output;
wherein the amplifier module has a fixed linear amplification gain in a range of 10 to 12 decibels;
wherein the amplifier module is configurable to provide a fixed gain bass boost additive to the fixed linear amplification gain;
wherein the fixed gain bass boost reduces signal distortions over a predetermined range of bass frequencies;
wherein the fixed linear amplification gain and/or the fixed gain bass boost are configurable to be on or off and otherwise not adjustable; and
wherein a control of the audio signal is effected solely by the sound volume control of the sound source.
