    This circuit amplifies three input channels consisting of low-current voltage signals that have a low bandwidth (less than 200 Hz). Each channel is pre-amplified according to a fourth circuit input which operates as a voltage control to the pre-amplificiation. Each pre-amplified channel is then fed to a class D amplifier to create a large current version of the input at three respective circuit ...
