I was able to clean out a noticeable level of grunge and noize by installing a pair of Ferrite cores on the AC receptacle providing juice to my audio system as well as the receptacle of my refrigerator (surprisingly more effective than the former). Your mileage may vary but I found this method actually performs better than merely wrapping it on AC cords( which I also have done).
Noise Filters & ferrite beads....
I am building a preamp based on DACT's attenuator (DACT2) and DACT's buffer CT101. It will also include a DAC (EVAL board) from Analog Devices based on the AD1895 192 kHZ Stereo Asynchronous Sample Rate Converter. For the buffer power supply I use two OMRON S82K-3W single output 24V 130mA power supplies connected in series to generate +/-24V. The output is filtered by a paralel bank of 6 1,000uF 35V capacitors.
The DAC's power supply is also made by Omron but this time I decided on a dual output +/-15V instead of the series connection...
Recently I came accross a 250v-20A noise filter made by TDK on sale at www.allelectronics.com (ZAC2220-11)
To make a long story short: is it worthwhile to insert this noise filter before the switching power supplies? What will be the effects (positive or negative) of doing this?
Also, I've added ferrite beads to the wires connecting the power supplies to the capacitor bank... Don't know if this is going to do any good either... Any comments?
All responses will be greatly appreciated. What started as a small little project is turning into a mountain...
