Strømrensing eller dynamikk...eller begge deler ?
Med tanke på trådens navn, så burde det jo være mulig å få begge deler, men det gjør man ikke alltid, litt avhengig av hva man bruker for utstyr.
Dette er gammelt nytt for mange men med relativt strømsterke mono-blokker så har man erfart under uttesting av div filtre at dynamikken forsvinner til fordel for en anemisk fremførelse, det gjelder å velge rett.
Selv fikk man lete litt utenfor allfarvei for å finne det som funket...

Litt FAQ
ANSWERS TO MOST FREQUENTLY ASKED QUESTIONS
Q WHY CANT SINE WAVE RESHAPERS/GENERATORS SOLVE THIS PROBLEM?
Answer
Power regenerators, perform as designed, convert AC power to DC, and then back to AC. This technology was developed during the Second World War to provide cleaner power on naval ships.
Wired in series to the line, this approach has its own sonic signature. Being their own power amplifiers, they consume as much or more energy than they create. This wasted energy dissipates in the form of substantial heat.
They provide a local solution to front-end source components plugged directly into them; however, they are limited as to the demands of current hungry amplifiers and receivers that can cause the power regenerators to shut down. Often demand outstrips supply.
Q WHY VOLTAGE REGULATORS CANNOT CURE THIS PROBLEM?
Answer
Your equipment is designed to handle voltage swings of plus or minus 8%, so rarely would you need to have a voltage regulator in our systems.
Actually, when you increase voltage you decrease available current on demand. If indeed you have sustained voltage below 100-volts in your home, we recommend you should contact your utility company provider.
Should you have voltage sensitive equipment that is improperly designed from the start you might consider purchasing a professional grade voltage regulator.
Q HOW DOES RGPC DIFFER FROM ALL OTHER POWER RELATED PRODUCTS?
Answer
RGPC is wired in parallel to the A.C. line, between the A.C. outlets and the components, so it cannot limit current because it adds no resistance to the line.
Wired to the hot and neutral leg of the circuit, electricity doesnt actually flow through the device; therefore, power flows straight through to your equipment.
It restores back onto your soft or weak AC line instantaneous high-current-on-demand to satisfy transients of power hungry amplifiers and powered subwoofers. Names upon request.
To our knowledge it is the only power management device recommended by so many manufacturers of amplifiers and video equipment.
Q EXPLAIN HOW RGPCS PARALLEL INDUCTOR REMOVES AC LINE NOISE?
Answer
Noise, is a catch all phrase which usually applies to random signals that ride on top of the desired signal. Most noise on the AC line has a fast rise time and is of short duration.
Most loads in your home are inductive; i.e., motors, televisions, power supplies, hair dryers, air conditioners etc. With these inductive loads in series to the AC line you get a shift in the AC wave (power factor), and generates impulse noise.
The RGPC choke places an inductive load in parallel with the AC line so you get a cancellation of the series load, thereby regenerating a cleaner AC wave form.
This noise is random, of short duration and potentially high in amplitude above the AC. The custom inductor of the RGPC, due to its low impedance absorbs this noise, not allowing the signals to proliferate past the unit.
Q HOW DOES RGPC IMPROVE VIDEO PERFORMANCE?
Answer
The RGPC patented electrical Fly Wheel effect works cycle-to-cycle to overcome lapses in an electrical circuit, absorbing all spikes and filling in the dips, when demand momentarily overcomes supply.
It yield a more consistent laboratory grade of noise free power necessary for increased image depth, black level detail and color fidelity on all video formats, including the latest projectors and plasma screens.
Q HOW TO EXPLAIN THIS HUGE TECHNOLOGICAL ACCOMPLISHMENT?
Answer
It is best explained by analogy to a mechanical flywheel in a car, that doesnt create energy, but rather helps sustain it.
The patented design includes an extremely large inductor surrounding a unique core structure.
This inductor, one of the largest ones ever made, or choke is positioned in parallel with the A.C. line providing the straight-through path your components require to work as they were designed.
Q IS A CHOKE OR INDUCTOR THE SAME THING AS A TRANSFORMER?
Answer
Yes and no, it is constructed like a transformer, with hundreds of feet copper wire surrounding a proprietary iron core, but has it has two taps rather than four.
An iron core choke, wired in a pi-network is not a new concept, and is being used in some high-end audio products today for voltage regulation. Although similar technology, it is not the same application as the RGPC, and is wired in parallel to the line.
Q HOW DOES THE RGPC INDUCTOR OPERATE AS A CAPACITOR?
Answer
The huge RGPC inductor operates as a reactive entity under alternating-current conditions. It resists changes in current flow by storing energy within a magnetic field.
When current passes through the inductor, a magnetic field accrues in the core, and around the coil. When current ceases, the magnetic field collapses, restoring stored energy to the circuit.
Q WHY CANT YOU SEE OR HEAR RGPC IMPROVEMNTS MORE QUICKLY?
Answer
One of our serious challenges is the desire on everyones part for instant gratification; unfortunately, and although we ourselves hear and see some difference almost immediately, our technology must be inserted into the circuit at least overnight, and then simply unplug it while the equipment is playing to witness the subtle to dramatic positive improvements.
This is the same for the break-in period required for most electronics. You would not plug a cold amplifier in and pull it out of a circuit to determine a comparison to another cold amplifier. To make meaningful comparisons an amplifier needs to warm up and break in properly.
Q DOES RGPC PROVIDE SURGE SUPRESSION?
Answer
Yes, it provides state-of-the-art dual-stage surge suppression both from the lethal spikes and constant smaller surges that plague electric parts causing eventual failure and making components work harder to overcome line anomalies.
Q HOW DO REGULAR SURGE PROTECTION DEVICES DIFFER FROM RGPC?
Answer
Conventional line conditioners use various types of surge suppressors, most commonly relying on an MOV (Metal Oxide Varister), to protect electronic equipment from large energy surges or nearby lightning (EMP) strikes.
Most MOVs are sacrificial, designed to self-destruct when the big hit comes along; unfortunately, in conventional PLCs, the smaller constant surges continually bombard the MOV with extraordinary stress resulting in fried bits that have to be replaced routinely.
These small spikes pass through these MOVs and reach your sensitive electronics, and with repeated abuse by exposure to these smaller voltage spikes can eventually break down solid-state devices.
Q HOW DOES THE RGPC DUAL SURGE SUPPRESSION SYSTEM WORK?
Answer
The RGPC giant choke (weighs 20 lbs and has over 1000 feet of wire surrounding its core) is the first line of defense.
It is designed to place a very low resistive load in parallel with the line as protection against all spikes that usually appear as DC-based, short-term pulses.
With additional RGPC units star-clustered in parallel within a circuit, the resistive load becomes lower still and surge suppression becomes even more effective.
Q HOW DOES THE GIANT RGPC CHOKE PROTECT ITS INTERNAL MOV?
Answer
By analogy to football, an RGPC unit has a 500-pound tackle (huge inductor) protecting the quarterback (MOV). Without RGPC parallel surge suppression technology leading interference, the spike would have been passed along the line to do its dirty work.
RGPC technology protects the on-board MOV as well as your sensitive electronics from destruction by absorbing spikes and noise before they get to any level high enough to cause the triggering of the MOV. Only in the RGPC does the MOV not self-destruct, rather, it throws the surge over to blow the internal in-line fast-blow fuse.
Q SHOULD ALL COMPONENTS BE PLUGGED DIRECTLY INTO THE RGPC UNITS?
Answer
Since RGPC is wired in parallel, it operates GLOBALLY within the same circuit. All equipment plugged into the same circuit on which RGPC resides will receive the full benefits from the RGPC line enhancement technology without having to be plugged into the RGPC unit itself.
One entire modest home theater system can receive full treatment from just one RGPC being plugged into the same circuit.
On the other hand, series type power line conditioners operate LOCALLY, which means all equipment must be plugged into the PLC itself in order to remove line noise.
Q WHAT ABOUT POWER AMPLIFIERS AND POWERED SUBWOOFERS?
Answer
We suggest you plug your basic power amplifiers (not integrated or receivers) and powered subwoofers directly into your wall outlets with the RGPC units plugged into the adjacent duplex wall outlets to take full advantage of our non-current-limiting parallel AC line enhancement and energy saving technology.
Basic power amps and powered subs do not need surge suppression because we feel their own internal transformers adequately protect them.
All remaining components should be plugged into the RGPC units themselves to take full advantage of our dual stage surge suppression system.
Q WHAT IS THE BEST WAY TO EVALUATE RGPC IN YOUR SYSTEMS?
Answer
Merely by plugging one or more RGPCs in parallel somewhere within each A.C. circuit, with no equipment plugged into it at all. Remember all equipment plugged into the same circuit with a RGPC being on the line will receive RGPCs patented global power management enhancement.
Leave installed for several hours to several days, and while playing the system, have someone unplug them while you are sitting in the sweet spot and/or watching your video picture.
The improvement will be anywhere from subtle to dramatic depending upon the needs of your system on your household electricity.
All components on all circuits need be enhanced with RGPC for best results.
Q SHOULD WE REMOVE POWER LINE CONDITIONERS AND SURGE PROTECTORS?
Answer
Yes, and maybe not
While evaluating RGPC parallel technology (which means electricity does not flow through our device; rather past it), we highly recommend removing your traditional series type, current-limiting POWER LINE CONDITIONER, not only from your system, but from the AC wall outlets as well.
This is not to imply that your PLC doesn't remove noise as claimed, rather that you may no longer be satisfied with it's trade-offs with your equipment. In many cases, PLCs and RGPC can work well together, but this compatibility varies from system to system.
We suggest the PLC can be retained for use on the incoming cable and telephone lines that RGPC does not address.
Q WHY INVEST IN A RGPC IF WE ARE CONSIDERING PURCHASING MODEST EQUIPMENT?
Answer
A more modest receiver powered by a RGPC will perform better than a more up-scale model without RGPC on the circuit.
It virtually makes a boom box sound better, and even a few have purchased the smallest RGPC to do just that.
Q HOW MANY RGPC UNITS CAN I PUT INTO MY SYSTEM?
Answer
Other than reasonable financial constraints, and reaching a point of diminishing returns, and the limitation of available AC receptacles, there does not seem to be any technical limitation.
The more units installed the higher the current on demand and the lower the noise floor. If your equipment is split among different dedicated AC circuits it is always better to place one RGPC on each circuit then cluster them all on one circuit and leave some equipment on circuits not treated with the parallel RGPC technology.
