FREQUENTLY ASKED QUESTIONS

QUESTIONS:

WHY DOES PURESOUND CABLE USE OXYGEN FREE COPPER (OFC) AS THE CONDUCTOR AND SHIELD MATERIALS?

Oxygen free copper or (OFC) is a copper alloy that has been refined to remove all but a trace amount of oxygen. By removing oxygen, as well as a host of other impurities, you are left with a metal that is far more conductive and far less susceptible to corrosion. This process leaves you with a wire that provides better clarity of sound, and lasts longer than other, less pure, copper wires.

WHY DOES PURESOUND CABLE SILVER PLATE THE CENTER CONDUCTOR AND SHIELD, EVEN THOUGH YOU ALREADY USE OXYGEN FREE COPPER (OFC)?

Silver plating is used to protect the oxygen free copper (OFC) conductor(s) and shield from accelerated oxidation. Silver offers extremely high conductivity and boosts the performance by allowing for reduced resistance and lowered transfer impedance. Thus, maximizing the cables efficiency. Also, the solder-ability of silver plated conductors is excellent, giving you strong reliable connections.

ARE ALL OF YOUR CABLES HAND SOLDERED? AND WHAT KIND OF SOLDER DO YOU USE?

Yes! Here at PureSound Cable, each cable is hand soldered and quality checked by skilled and qualified cable technicians before being shipped. Most companies use a low quality, inexpensive rosin core bulk solder, in which, over time begins to weaken and corrode. We use quad eutectic silver solder. Silver solder, has higher conductivity, a stronger bond, and it’s less susceptible to mechanical fatigue, which in return, makes a strong reliable connection.

WHAT IS THE BEST LENGTH TO USE FOR INSTRUMENT CABLE? I'VE HEARD THAT YOU REALLY SHOULDN'T USE A CABLE LONGER THAN 20FT?

Ultimately, when working with any cabling application(s), the shorter the better. This is obviously not practical in every situation as you do not want to go so short that you are uncomfortable on stage or in the studio. The reasoning behind this is, the longer the cable is, the more capacitance builds up. Capacitance is a low-pass filter between the instrument and amplifier; that cuts high frequencies. Similar to the instrument’s tone controls.

CAN I JUST USE A GUITAR CABLE FOR MY AMP TO SPEAKER CABINET?

We DO NOT recommend this practice, as SPEAKER cables have very different specification requirements than INSTRUMENT CABLE. An instrument cable is designed to handle low power and high impedance, while a speaker cable is designed to handle high power and low impedance. The two should NOT be used interchangeably.

WHAT TYPE OF CONNECTORS DO YOU USE? WHY DO YOU USE THE GOLD PLATED PLUGS OVER THE NICKEL PLATED?

Our standard is to only use premium connectors that are available on todays market.  Heavy duty professional connectors with gold plated contacts made by Neutrik or Amphenol for speaker and pedal cables. They are the gold standard for connectors in the studio and on stages across the globe. Gold is not only a far better conductor of electricity, but also less corrosive and lasts longer without tarnishing. Neutrik and Amphenol connectors both utilize a clamp chuck type strain relief, which is extremely effective and important in real life performance situations. This means they can take being bent and twisted time and time again without failure. The robust die-cast shell is extremely durable and still stylish. The precise machined one-piece tip contact without rivets, makes it unique and avoids hook up in a socket or break off the tip.

WHAT IS THE SILENTPLUG OPTION?

The SilentPLUG automatically mutes (shorts) an instrument (guitar) cable to avoid pops and squeals when changing the instrument (guitar) under load. The integrated silent switch is based on REED-technology and guarantees a lifetime beyond 10,000 mating cycles. We highly recommend using this option for guitars and basses especially.

WHAT IS THE BRAIDED MATERIAL USED TO COVER THE OUTER CABLE JACKET? IS IT USED JUST BECAUSE IT LOOKS COOL?

We use a high tech polymer meshing made by TechFlex.  Not only does it look great but it also serves a purpose.  It acts as another outer layer of protection from bending, kinking, slicing, and even protection form UV ray and harmful chemicals. Don't be fooled by others using knock off meshing claiming it is as good. Our TechFlex undergoes a process that is commonly used in medical and aerospace applications.  This makes it much more flexible which is very important when it comes to audio applications real world scenarios.

I PURCHASED A BARGAIN BRAND CABLE AND THE FIRST THING I NOTICED IS HOW NOISEY IT IS WHEN IT BENDS OR SMACKS AGAINST THE FLOOR.  WHEN I UNPLUG IT THERE IS THIS POP AND CRACKLE! DO YOUR CABLES PREVENT THIS FROM HAPPENING?

YES! The noise you hear is commonly known as handling noise and microphonics. PureSound Cables were specifically engineered to virtually eliminate noise. We use an electrostatic shield with not one but two layers of conductive low-noise coatings.  They prevent against outside interference and eliminating all handling noise and microphonic "pops & crackles."

WHAT DO YOU MEAN BY DIELECTRIC COATED RELIABLE CONNECTIONS?

Every PureSound Cable, no matter if it's an instrument, microphone, or speaker cable, etc. undergoes a process that is hand coated with a dielectric insulating material that goes over the soldering connections. This process not only insulates any wires from ever touching each other but it also makes the connection water resistant. 

WHY DO YOU USE A HIGH STRAND COUNT 20 AWG WIRE FOR YOUR CENTER CONDUCTOR SIZE?

We only used the highest strand count available for all of our stranded OXYGEN FREE COPPER (OFC) SILVER PLATED conductors. Higher strand counts mean increased production time using expensive and highly sophisticated machinery that is required to assemble the strands of a high strand count conductor. Higher, finer stranding increases the flexibility, strength, durability and the flex life of the cable. That being said, our high strand count center conductor is 20 AWG. We use 20 AWG because of its' tensile strength.

I HAVE SEEN BRAIDED AND SPIRAL SHIELDS FOR AUDIO CABLE. WHY DO YOU CHOOSE THE SPIRAL OVER BRAIDED?

We use a silver plated oxygen free copper (OFC) 97% coverage spiral shield for many reasons. Our spiral shield is extremely flexible. Braided shields simply are not. Superior flexibility often makes it more reliable. Braided shields can fail by being kinked and pulled, as often happens in performance situations, while a spiral shield will simply stretch before actually breaking down. We use maximum coverage for greatly reducing RFI, EMI, and ESI. Meaning your cable will not be picking up any radio stations, cell phone noise or annoying buzzing from the fluorescent lights above the stage.

WHAT IS THE INSTRUMENT CABLES CENTER CONDUCTORS INSULATION MATERIAL? AND WHY IS IT IMPORTANT?

While it might not seem very important to the makeup of our cable, but it actually is. We use a high-density cellular poly foam. Not only does it act as a dielectric insulator for our center conductor, but it also dramatically lowers the cable's capacitance. Making PureSound Cable neutral and extremely clear sounding through the entire frequency range.

MY CABLE HAS SEEMED TO STOP WORKING PROPERLY?

Although it is extremely rare for a PureSound Cable to stop working properly, no need to worry, PureSound Cable has a hassle free limited lifetime warranty. For more information, please visit our warranty policy.
