Circuit Design: 3-Channel Class D Amplifier with PreAmplification And Other Logic

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 outputs. The class D amplifiers should reuse as much circuitry between each channel as possible

There is some other logic that is fairly simple but I'd prefer to disclose it after project reward.

Given the simplicity of inputs and the objective outputs, simple and low-cost circuit design is preferred (i.e. this is not a HI-FI system).
