Custom EF series covers painted by Gilbert...audiophile tweak with artistic touch

Gilbert is now focusing his time on what he enjoys most....creative design. This time he's come up with a doozy....using Mechanical Damping Material to reflect and thereby eliminate microvibration on EF powerline conditioner series units.

Anyone interested in making a custom colorful cover for their Entracte Audio by Design EF filters, can contact TLP Audio for pricing. A variety of unique colors and designs are available.


EF/TF Powerline Filter Series

For the past 15 years, TLP Audio has been selling the best value powerline filters from Blue Circle Audio. It is only a natural progression for us to offer Gilbert's newest designs as the NEW best value powerline conditioners possible. After many hours of discussions with Gilbert,and knowing how his creative mind works, he has designed a new series of powerline filters: the models TF50 and TF100 (exclusive to TLP Audio), EF110, EF120, EF130, and the HIGH CURRENT models: the EF215 and EF220.

Although the underlying design of these units is similar to the legacy Blue Circle models, the latest filtering technology is used.

All of these filter models 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 powerline noise over a wide frequency spectrum
  • Carefully placed multiple ground systems to create complete external coverage rejection of RF and EMI

  • Note

    As of 10/20/2020 the TLP Audio powerline filter models:
  • TF110
  • TF120
  • TF130
  • are renamed to the EF110, EF120, and EF130, and will be sold and marketed under the Entracte Audio brand name. While the original vision was to have individual product names for the USA and Canadian markets, the success of these powerline filters has made it clear that having more than one brand name for identical products provides unnecessary confusion for our potential customers.

    In addition, as Entracte Audio and TLP Audio continue to collaborate with Gilbert Yeung Design, product updates and new product designs will be more efficiently and more quickly implemented under a single brand name.


    EF110, EF120, EF130 Design Considerations:

  • are enclosed in a metal chassis
  • have 6 outlets
  • include an AWG14 power cord.
  • How do these units compare to the legacy Blue Circle models?

  • The EF110 has 35% more filtering than a BC Double Puck and has a total of 6 outlets, compared to the Double Puck's 4 outlets.
  • The EF120 has 15% more filtering than the BC FX-2 X0e.
  • The EF130 has 20% more filtering power than a BC 660si. The EF130 is destined to become the value leader of the power conditioner pack.
  • There is more to these new designs than just filtering power. Specifically, it's HOW these filters actually work. Some products, that we all use every day, actually generate noise that they dump onto our powerlines thereby causing noise pollution. Some good examples of this are electronic devices using digital power supples such as computers, video monitors, and televisions. Also, a few of today's audiophile-grade power products even generate noise that pollutes powerlines.

    Although it sounds hard to believe, some companies' powerline conditioners alter the sound, of gear plugged int them, rather than clean the powerline. This means that they change the sound in such a way that it provides the customer with the sound that an audiophile expects to hear. The EF powerline filters, like the legacy Blue Circle powerline conditioners, remove powerline noise so that the power that gets to your gear is similar to what you'd get on a clean powerline. The Gilbert-designed powerline conditioners always clean the powerline and let the equipment perform at its best.

    The new EF-series technology has circuitry that combats other issues that come from switching power supplies, big industrial motors and other electronic devices that might occur within and outside your home or office. The performance of these new filters has to be heard, or watched on a TV to believe how much better they are compared to the legacy BC models. Other than electrical improvements, these new units are also housed in a metal chassis to improve noise sheilding from the outside. This results in an even lower noise floor.

    TF110 power conditioner

    The EF110 has one circuit board.

    A number of folks have asked us, via e-mail, if these units use the same filters as the former Blue Circle PLC units. The short answer is: yes and no. Yes, because these are capacitor based power line filters with no current limiting and because they use different values of capacitance to create networks specific to the various frequencies ranges of electrical dirt. Definitely the same general approach.

    TF series outlet view

    No, for a number of reasons. First - and most obviously - all of the EF powerline conditioners are housed in a metal chassis for better shielding from external airborne noise. Second, these new units all use a multi-point ground system, implemented for a better and stronger earth-to-ground path. As an added benefit, the new ground desgin helps lower background noise. No question, it's quieter. Third, more advanced capacitance networks are being used, with greater overall filtering power.

    The EF120 has 1 circuit board and is fully populated with filters (bottom pic). EF 120 series

    The EF130 has 2 circuit boards with even more filters (top pic).

    The original Blue Circle PLC line taught us all much about addressing specific frequency ranges in powerline filtration. What Gilbert has designed for us here are units that are more powerful than ever before, and offer "best bang for the buck" in their respective price ranges.

    EF High Current Powerline Filter Series

    The EF215 and EF220 are high current filter designs with 2 power outlets for systems with source components set up in one end of the room and power amp(s) in the other end (speaker end) of the room. For power amps, or speakers or subwoofers that sit between two speakers, there is no need to have a powerline filter unit that has 6 outlets. For a stereo amplifier or monoblock amplifier, two outlets is ideal for this set up. However, if you need a more outlets, for a pair of monoblock amps and a pair of subwoofers, 4 outlet units are also available.

    Since we have the above system setup in mind. Why not design a filter network specific for high current components such as a dedicated power amp or monoblock amplifiers? With the these design goals in mind, these units are the next evolution of the Entracte Audio power conditioner lineup.

    EF215/220 power conditioners

    These EF200 series models have the same design theory as the EF100 series however, the internal filter networks are specifically designed for high current, and high-speed response with hand-selected components. They also feature double 10 awg internal wire (equal to bigger than 8 awg wire) for ultimate high current transfer without any bottleneck effect. EF215/220 internal view

    Why two models?

    The EF215 has a 15 amp power inlet and the EF220 has a 20 amp power inlet. Power cords are included.

    > Most homes have only 15 amp wall outlets that make using a 20 amp unit unnecessary. The EF215 is therefore a perfect fit for such situations. For those who have gone the extra mile to install a dedicated 20amp power line from the electrical panel to their listening room, the EF220 with a 20 amp power inlet is the unit of choice. It features a 20 amp power inlet to match with the included 20 amp power cable. Therefore, from the electrical panel all the way to the power amp there are 20 amp wires and components.

    In addition to the features above, other 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 powerline noise over a wide frequency spectrum
  • Carefully placed multiple ground systems to create complete external coverage rejection of RF and EMI
