小弟向以Cardas caps插住 unused inputs （現在可以收埋）

昨天網上爬文得知原来可以short咗D plugs 來減少noise:

3-10 Shorting unused inputs
Pre-amplifiers, receivers etc. often have many selectable audio inputs of which not all are used.
The unused inputs are left open and along this way it is sometimes possible for electrical noise and radio frequency
interference to leak into your audio signal.
This is dependent on the quality of the internal circuitry and construction of the audio device in question.
Electrically shorting the unused inputs is a good idea to make sure that this crosstalk path is effectively blocked.
So, go to your audio dealer and buy some cheap RCA type male connectors. With each connector solder a very short wire
between the center pin and shell so that the plugs are electrically shorted. Then insert them in your unused inputs.
You may well find that your noise floor is lowered and that the audio has become cleaner.
