PNS-1 is a DC power distributor with a powerful built-in noise filter. By connecting this to a commercially sold 9V adaptor (*Specifications of compatible adapters are listed in below Description of Functions column}, you can distribute clean electric source from the DC with significantly reduced noise element to multiple effects.
During the recent years, popularity of switch-type adapters has grown very quickly. Although these adapters have wide range of input voltage, are smaller in size and weight, and capable of high capacity output current, because of their structure, they are known to cause very specific high frequency noise.
PNS-1 uses powerful noise filter to significantly eliminate this high frequency noise but its system is completely passive and will not consume incoming power.
It is also effective in significantly eliminating the noise element when you connect linear-type adapter.
Each input and output terminals are setup with protective circuit. This is a counter measure against troubles caused by misusage such as using wrong output short-circuit or polarity.
