Why does it make sense to exchange my current powercords to shielded ones from AUDIO-TUNING-PITHAN?

Generally an exchange of current used powercords to shielded ones is recommended, because it is almost impossible to avoid laying powercords and signal cable parallel. The 50Hz-hum in the ambiance of unshielded powercords affects the tiny signals in audio-cables in a negative way. In the most unfavorable case, an annoying hum is hearable through the speakers. You can avoid this problems with shielded powercords from AUDIO-TUNING-PITHAN. Furthermore, the high cross-section of 2,5 sqmm of each wire guarantees an almost loss-free transportation of the electrical energy to the connected devices.

What is the difference between a cold-device-plug and a warm-device-plug?

A cold-device-plug at the end of the powercord is used, if the connected device can´t become extraordinary warm or hot. Because of its special shape with this kind of plug it is not possible, that they can plugged into devices like electric irons, waffle irons, heaters, boilerplates or powerful power amplifiers. This kind of plug is manufactured out of thermoplastic material and would be deformed if heated up too much. A warm-device-plug in contrast consists of heat resistant duroplastic material and can be used for every device, also for components which become hot. All plugs used at AUDIO-TUNING-PITHAN are warm-device-plugs, thus it is ensured that our powercords are for universal use and will fit to all commercial HiFi-components.

What is the particular advantage of the multiple socket outlets with filter from AUDIO-TUNING-PITHAN compared with products of other manufacturers?

All multiple socket outlets from AUDIO-TUNING-PITHAN are equipped with a ferrite-ring at the end of the cord, in front of the device-sockets. This ferrite-ring acts as filter, because it is blocking interferences coming from the mains-network, like distortions from switches and motors. This interferences usually transfer energy with high frequency, for which the ferritte-ring is almost a short circuit. Thus negative influences on the sound are decreased and can´t get further to the connected components.

What is the difference between multiple socket outlets with filter FNL6 and FNL6S?

The multiple socket outlet FNL6 does not contain a mains-switch, because multiple music-lovers are the opinion, that a switch can alter the sound in a negative way. The multiple socket outlet FNL6S has - similar to the FNL8 and FNL10 - a mains-switch, which nevertheless can be bridged on demand before delivery without extra costs. The deterioration in sound which is caused by a switch is relatively small and should not be overestimated. At this point, other aspects should be considered, for example the simple way to disconnect the complete equipment from mains power if leaving the house for vacation. Furthermore both multiple socket outlets with filter are manufactured by different companies. The sound enhancement however is absolutely comparable.

In which position of my HiFi-equipment should I place the line filter NFL50, if I have only one?

If you have only one line filter NFL50 - this is the minimum configuration - it is recommended to connect the most used digital source-component. This can be for example a CD-, SACD- or DVD-player. With this configuration you will obtain the optimal sound improvement. There are two simple reasons: First: a source-component is very sensitive against hum and high frequency interferences Because the musical informations, existing as electrical signal-voltages, are very low at the beginning of the chain and afterwards, every unwanted signal which is not part of the record, will also be amplified. Second: every digital device causes unwanted harmonics during its digital-to-analog conversion which can´t be filtered out to 100 percent. These harmonics get back into the mains and can affect other devices, like pre- or integrated amplifier in turn. The line filter NFL50 acts bidirectional, that means, it reduces distortions in both ways: to the connected component and also back from it (return loss).

In which positions of my HiFi-equipment should I place line filters NFL50, if I have more than one?

If you have more than one, place the first one as described above (FAQ 5). The second line filter should be connected to the pre- or integrated amplifier. If your CD-player is separated into drive and converter, it is recommended to provide one filter for each of both devices. If you only listen to an analog source, the first filter should be placed in front of the turntable and the second in front of the phono-, pre- or integrated amplifier. Proceed similar if you have a tape- or cassette-deck.

Does it make sense, to connect two line filters NFL50 directly in series?

If two line filters are directly connected in series in front of a component, there will be no further sound enhancement. Contrariwise there can be a loss of sound quality due to overfiltering.

Can I connect my complete multiple socket outlet to the line filter NFL50?

From electrical side this is no problem because the maximum permanent load capacity of the NFL50 is 2.300 Watts and hence sufficient to drive even extremely powerful amplifiers on speakers with low efficiency. Even if you hear music at a very loud level, the permanent power output does not reach more than approx. 50-100 Watts. The peaks of power-pulses, which usually last only a few miliseconds, required by the speakers at certain musical events (drumbeat, very low organ notes), can be up to factor ten higher. Since the load capacity of the NFL50 for pulses is much higher than the permanent load capacity, there will be no dynamic compressions. Anyhow this alternative is recommended only if the power supply system is strongly interferred and you frequently can hear cracks and/or hum from the speakers. Furthermore with this alternative the advantage of return loss does not apply, look also FAQ 5.

Can I connect a component via a filter powercord L100KF to the line filter NFL50 or NFL100 and this itself to a multiple socket outlet with filter, or is this too much?

This combination is explicitely recommended, because the properties of the filters are tuned harmonically and no "overfiltering" can occur.

Do the cables from AUDIO-TUNING-PITHAN need a "burn-in-time" or is the sound improvement always directly recognizable?

All new cables, regardles if power-, audio- or speakercable, need a more or less long "burn-in-time". During this procedure, the crystal structure inside the conductor and the dielecrical property of the insulating material are altered. This procedure can last, depending on the cable itself, the connected component and the listening level, between 10 und 50 hours. After this period the whole sound-potential of the cable can be obtained. Some dealers even offer so called "burner" which should reduce this timespan. Don´t wonder if the sound of a new cord or multiple socket outlet does not fulfil your expectations, here you must be a little patient!

The standard powercord on my component has one of these small Euro-plugs "razor-plugs".
Can AUDIO-TUNING-PITHAN manufacture a powercord terminated with this plug?

That plug is a so called C7-plug which you will sporadicly find in source-components. The power-rating of this type is smaller (6 Ampère) than at a warm-device-plug, Since these plugs are sealed with the cord, a termination is laborous and costly. Furthermore there are types with small variations on the market. AUDIO-TUNING-PITHAN can terminate after a detailed description of the plug-type (photo via E-Mail) for additionsal charge of Euro 10,- for each cord.

If I decide to buy at AUDIO-TUNING-PITHAN, can I pick up my goods directly at company site?

Yes, you can pick up your goods at company site after arrangement and thus you will save the shipping costs.

Do I get quantity discount if I buy larger number of items?

If purchasing larger amounts of goods, you´ll get an additional discount depending on the price.

Can I use powercords from AUDIO-TUNING-PITHAN for british components without protecting earth wire?

Yes, for example components from Linn, Cyrus, Naim, Mission, Creek, Arcam, Camtech or NAD can be connected without problems.

I have only two components, is it recommended to connect these without multiple socket outlet directly to the double-line-filter NFL100?

If you have only two devices, e.g. CD-player and integrated amplifyer, this is the optimal solution. Both components are connected in the best way and protected against distortions. The standard-cordlength of the NFL100 of 0,5m can be modified by us according to your room-conditions.
