6.8. Connecting a buffer capacitor
In sections with bad contact to the rails the power supply of the
decoder can be interrupted. Possible consequences are e.g. flickering
lighting or disturbing noises from the loudspeaker. In these and similar
cases you can find a remedy by connecting a buffer capacitor. The
electrolytic capacitor should have a capacity of minimum 220 µF and an
electric strength of minimum 35 V. Observe the correct polarity when
connecting the capacitor!
6.9. Connecting a suppression choke
As a matter of principle the sound playback can be distorted or
disturbed by a high whistling noise. In this case you should solder a
suppression choke (> 470 µH / 90 mA) into one of the supply wires of
the loudspeaker.
