B-C-S Type Switchable Stereo Processor
Fig. 4 shows the stereo processor switchable to any B-C-S type mode. The operational amplifier is unnecessary,
because the CXA1563 is used for a B-C type processor and S-type changeover switch is built in the IC. It is
recommended that the S type mode be used for recording level calibration.
