Pin 25 is an open-collector output (active-low) as shown in Figure 6.
When the output voltage waveform is clipped, the internal clip detector is activated so that the NPN
The sound quality can be improved by controlling the volume and tone control circuitry using this output
Pin 25 should be left open when this feature is not required.
