The wife asked me to stop by....WOW....11 pages??? What's up with that??? Does anyone have any questions on the product?Regards,Alan MaherAlan Maher Designshttp://www.alanmaherdesigns.com
Hi AlanWelcome to AudioCircle! Jen has been wonderful in trying to sort out our myriad queries! For simple minds like me, I think diagrams would help to show the many permutations that your excellent power enhancer can take. From what I gather, most are confused with: (1) difference between series and parallell, that is, the difference between "prior to your system" (after ~) from "same outlet as the component"; (2) orientation of the PE (newer version with only 2 pins).Many thanks,Best RegardsDennis
Hi Dennis"From what I gather, most are confused with: (1) difference between series and parallel, that is, the difference between "prior to your system" (after ~) from "same outlet as the component"; (2) orientation of the PE (newer version with only 2 pins)."1. Series and parallel is the difference in how the duplex outlet is wired in reference to the filter and component. US spec outlets use a straight buss between the top and bottom receptacle to pass electricity. The buss that is located on the side of the duplex causes the series vs parallel dilemma. What we would like to see is the following:All in wall wire enters the duplex via the bottom receptacle. The PE plugs into the bottom receptacle. This arrangement places the PE in series with the top receptacle. With that said, the side H/N buss passes the PE filtered a/c to the top receptacle. Plug the component into the top receptacle. This description is what I consider to be series filtering. Series filtering removes stray inductance prior to the PE on the circuit and injects our filter bandwidth (ringing frequency) into the component which is placed after the PE on the circuit. Parallel filtering is just the opposite, the in-wall wiring enters the top receptacle. The component is plugged into the top receptacle, and the PE is plugged into the bottom. In this situation the PE will increase the magnetic build up (increased inductance) inside the outlet. Series provides a bright/more dynamic sound and parallel provides a warmer tonal balance. Series also provides power factor correction, circuit isolation, and rfi / emi reduction. Parallel only provides rfi / emi reduction. 2. The PE has NEVER been designed with 3 prongs. It has always been a 2 prong filter. We use the case vendors stock photo on the web site because Jen's digital camera sucks. The pictures always come out dark and fuzzy. If anyone would like to take a picture of the filter I would be greatly appreciated.

...In order to deal with larger surges I would recommend 2 to 3 PE's to be used on non-a/v circuits throughout the home. Unless your Furman is a IT Ref model (balanced ac), the other models are all passive parallel units with a simple MOV circuit. The MOV does zippy do da to prevent electrical surges from passing via the neutral or earth ground. The PE can greatly reduce the magnetic build up on the hot and neutral wire with 1 pico second respose time. As I mentioned more than 3 are required to deal with the entire breaker box, but it is a very good investment...
Huck"1. I have 3 PE's on order, before I start, should I check to see which way my duplex receptacles are wired... that being "hot" going to the bottom "brass" screw and also the "neutral" going to the bottom "silver" screw?" Yes...all wiring should be wired into the bottom screws."If o.k. I would plug the PE(s) in the bottom and my a/v component in the top?"Yes "2. Let's say that I want to use all 3 of my PE's in my audio room and let's say I have three separate duplex receptacles spaced from right to left. Lets call the far right one "A",middle one "B" and left "C". The middle outlet (B) is where I want to plug one PE, which will share this duplex with my Furman power conditioner, which is full with integrated, c.d. player,satellite receiver,a/v receiver,etc, ( one PE will go to the bottom, Furman on top.. correct?). The other PE, I would place at "A" which I think is "before" The duplex at "B" (I think the power comes that way from the breaker, from right to left A>B>C. I would place the last PE on the duplex at "C", being this is "after" All three ABC duplexes are on the same circuit!"Plug one PE into outlet A. Check the polarity of the outlet to make sure the wiring is not crossed. Plug the PE into the bottom receptacle.Check the wiring of outlet B. Make sure all wiring is wired into the bottom screws. On a shared circuit you will have 4 wired (2 hot and 2 neutral) and a ground. Both sets of hot and neutral wires must be installed into the bottom screws. Check the polarity of the outlet. Plug the PE into the bottom receptacle and the Furman into the top.Plug the PE into outlet C. Check the polarity of the outlet.Suggestion: I highly recommend adding 1 PE to the Furman. The Furman power cord will add a little stray inductance (EMI) to the circuit via it's internal wire geometry. A forth PE added directly to the Furman will eliminate the remaining EMI residue from the circuit."3. Let's say on of my intended duplexes is wired "wrong"...that being "hot going to top screw and "neutral" also going to top screw, do I need to change this first?! What if the hot is going to the bottom and the neutral is going to the top, should this be changed also!"All wiring must be installed in the bottom screws if you want to achieve series filtering."4. Is there any harm done to the PE's if say, the power should go out, and since the PE has already been "charged", will the extra boost, when the power comes back on hurt anything?"The PE's main job on the electrical phase is to reduce and eliminate stray inductance (EMI). Surge, spikes, and arc's are a form of stray inductance (RFI/EMI). These interferences are caused by magnetic build up on the electrical phase. The PE should be used to treat each circuit that shares the same phase as the a/v system. Let me give you an example of how noise travels. A lightning surge is considered noise in the form of EMI. Lightning strikes outside and can travel up to 1000 sq ft from the strike point. Any metal what so ever dug into the ground will become magnetized by the EMI field created by the strike. All homes use a ground rod in the yard to help deal with surge problems. The ground rod only works if it's tapped into the water table. In most cases the surge travels into the home via the earth ground. Inside the breaker box the earth ground is split with the neutral wire. All surges enter components either by the neutral, earth, or both. The hot (in coming service) is protected twice by two breakers. Of coarse some breakers are better than others, I usually recommend thermal magnetic breakers,,,they have the best response time. As I mentioned before, the PE's main job is to reduce stray inductance / EMI that is circulating on the phase. In order to deal with larger surges I would recommend 2 to 3 PE's to be used on non-a/v circuits throughout the home. Unless your Furman is a IT Ref model (balanced ac), the other models are all passive parallel units with a simple MOV circuit. The MOV does zippy do da to prevent electrical surges from passing via the neutral or earth ground. The PE can greatly reduce the magnetic build up on the hot and neutral wire with 1 pico second respose time. As I mentioned more than 3 are required to deal with the entire breaker box, but it is a very good investment.Alan MaherAlan Maher Designshttp://www.alanmaherdesigns.com
HuckDo you have any component that has rear outlets? Receiver, cable box, etc? The PE can be installed into the component unswitched outlet and do the same thing...the PE will also provide additional isolation for the selected component. Alan MaherAlan Maher Designshttp://www.alanmaherdesigns.com
Howard-It depends on what you considered star wired. We have seen many applications over the years labeled as "star wired" and it's not. Star wiring means you have 5 wires per duplex outlet. 1 wire is earth, 2 wires are hot (1 wired to the bottom screw and 1 wired to the top screw), and 2 wires are neutral (same wire design). We have seen many descriptions of star wiring, one example is to run one pair to duplex 1 and another pair to duplex 2. This design is for isolation, not star wiring. Star wiring is used to lower the ringing of the duplex.The PE cancels out stray inductance. The PE will change the sound to reflect a neutral (flat) presentation.I believe you are asking about the sonic difference with a star wire, well that is the best of both worlds, the PE will be placed in series and parallel. This will offer a little more neutral presentation with very good bass extension and punch. When Alan does professional installs he uses star wire geometries. Highly recommended to lower impedance.
