FAQ's
Reference - Are XLR 40 Analogue and XLR 40 Digital the same?
Answer: Many people misunderstand balanced line thinking that the two signals in the hot and cold wires just have to be equal and opposite for it to work and while this is often true, it is not this that makes the transmission line “balanced” or ...
Profile Audio - Q. How many strands does this cable have?
Answer: QED Profile Audio uses 2 x 7/0.12 strands twisted pair per channel for hot and cold in a quasi-balanced configuration on the signal and a heavy outer shield braid connected at one end, and it has a loop resistance of 450 milliOhm.
Q. What is the outer diameter of my analogue interconnect jacket?
Answer: Please find the jacket outer diameters for QED analogue interconnects as follows:
Performance J2J - Q. How many cores does this cable have?
Answer: There are 4 - left+screen & right+screen, but the screens are common both ends so its effectively three, as you would expect from a stereo interconnect cable (ie L,R & GND).
Signature Audio 40 - Are these cables cryogenically treated?
Answer: Signature Audio 40 cables benefit from a deep cryogenic treatment prior to assembly. The temperature of the cable is gradually reduced over a period of eight hours using liquid nitrogen and kept at a value of -196 8C for a period of 24 hours. ...
Audio 40 - Q. What is the diameter of the Analoc plug barrels at their widest point?
Answer: The Signature Audio 40 plug is approximately 13.6mm at it's widest point. The Reference Audio 40 plug is approximately 13.5mm at it's widest point.
Audio 40 - Q. Will the Signature Audio 40 sound brighter than the Performance Audio 40i?
Answer: Please kindly note that it is not possible to affect the EQ of the signal using a cable, so no cable can make your system sound brighter. What is affected though, is the 3D audio sound stage and illusion of realism which could be described as ...
3.5mm Jack - Q. Does the stepped jack mean that I cannot use a 6.35mm adaptor?
Answer: There should be no problem with attaching the stepped 3.5mm jack plug to a 1/4" adaptor. As per the attached example, it may look like it hasn’t gone all the way in but that’s because its 2mm longer than a usual jack, with a stepped design to ...
Q. Which analogue cable is capable of hi res audio?
Answer: Your network streamer has already converted the audio from digital to analogue, so it doesn’t matter how digitally fast the cables are because they are working in the analogue domain. Here, you need a cable with unsurpassed analogue audio ...
Q. Which QED cable is best to use with a turntable?
Answer: The QED Performance Audio 40i is a great choice - It has low enough capacitance (around 70 pF/m) and a coaxial construction giving it good immunity to noise from nearby large current carrying (mains) cables which turntables pick up really ...
Performance Audio 40 - Q. What is the capacitance of the QED Performance Audio 40 interconnect?
Answer: The capacitance of this cable is 76 pF/m.
Audio 40 - Q. Is the QED Audio 40 cable directional?
Answer: No, the Audio 40 range are not directional. This is because the cable is wired in traditional unbalanced mode, similarly to a co-axial cable, using the braid as both a shield and a path for return currents. This gives the cable exceptionally ...
Audio 40 - Q. Why are the conductors so small in your QED Audio 40 range?
Answer: QED Audio 40 cables are designed primarily to have low capacitance, we have found that these sound the best for various technical reasons. The larger the conductors the more difficult it is to keep the capacitance low so, we have used the ...
Signature Audio 40 - Q. What is the outer diameter of the QED Signature Audio 40 jacket?
Answer: The outer diameter is 8mm.
QED Profile Audio - Q. What is the capacitance of the QED Profile Audio cable?
Answer: The capacitance of this cable is 113 pF/m.
