⚡ Causal Link: Defect to Consumer Return
The combination of low-cost pre-amplifiers (ENG-001) on the Main PCB (COMP-001) with an inadequately filtered power supply (ENG-003, COMP-005) results in unacceptable noise levels on input channels, especially at higher gains, leading to complaints of 'excessive noise' (RMA-001) and consumer frustration (REV-001) who expected a 'professional' product.
