Abstract
An audio processing system has, at an input for receiving a balanced analog audio signal, an analog amplification stage having a first fixed gain and a first dynamic range. The system further includes an analog to digital conversion stage, having a second dynamic range that matches said first dynamic range of the analog amplification stage. A digital gain stage can also be provided to allow user selectable gain.
Claims26
An audio processing system comprising:
- an input for receiving a balanced analog audio signal;
- an analog amplification stage having a first dynamic range and a first fixed gain between −11 dB and +10 dB;
- an analog to digital conversion stage having a second dynamic range that matches said first dynamic range of the analog amplification stage;
- and
- a switchable attenuation stage between the input and the analog amplification stage, said switchable attenuation stage being switchable between an active state in which a fixed attenuation of an input signal is provided prior to the analog amplification stage and an inactive state in which the switchable attenuation stage provides no additional attenuation of the input signal prior to the analog amplification stage.
