Each input channel has its own microprocessor, the VCA master section has one and the final microprocessor is in the central control section. All the microprocessors are located in the fader bay of the XL4. No audio passes through the fader bay, allowing a high degree of immunity to digital breakthrough to be achieved.
Input fader mode control, later). The central controller CPU has been developed by OUTBOARD ELECTRONICS Ltd. in conjunction with MIDAS.
