Our power line filters have been  to provide maximum performance at a reasonable price. Designed by Gilbert Yeung (formerly of Blue Circle Audio) and built in Canada, we are proud to say that our power line filters outperform similar equipment that costs much more. We've eliminated fancy and put the emphasis on performance. Features include:


* Parallel capacitor-based filtration for zero voltage drop and no current limiting

* Each outlet has a short and direct path to the internal filters

* Multiple filter networks with specially selected Q factors, tuned to eliminate noise over a wide frequency spectrum

* Carefully placed multiple ground systems to create complete external coverage rejection of RF and EMI

Here is a 360 degree view of the EF130. As you can see, we've packed it pretty much full.
