What is an XLR connection?

An XLR connection is typically used in balanced audio connections such as microphones, speaker connections and mixing desks, where there is potential for high E.M.I. (Electro-Magnetic Interference) and R.F.I (Radio Frequency Interference).

 

What are RCA/Phono connections?

These are connections commonly found on home stereos. They comprise of a Red (Right) and White (Left) connection, although colours do vary. This type of connection can also be found on the back of Dj Mixers, Dvd players and televisions.

 

What is a Balanced Cable?

A balanced audio cable uses two signal carriers (2 Cores) for audio transmission. If two identical sound waves exist yet they are the inverted (180 degrees out of phase), so opposing each other, they cancel each other out and no sound will be heard. This is known as phase cancellation. A balanced audio cable utilises this principle. It inverts one of the signal lines so that both signal lines are completely out of phase with each other and re-inverts the signal at the opposite end. By doing this any noise that was inducted into the signal line across the cable is induced in phase and upon reaching the opposite end is inverted, so becomes out of phase, essentially cancelling out the unwanted noise.

 

What is Star Quad?

Star quad cable offers unparalleled rejection of un-wanted radio frequency interference (RFI) and electromagnetic interference (EMI) by using 4 cores of wire for transmission. It uses the exact same principle as the balanced cable description above but uses 2 parallel twisted cores of wire for each signal line. In normal balanced audio cables cores run in parallel but straight and side by side. If the cable was lying next to a mains cable which emits high EMI one of the cores would induct slightly more than the other so when inverted to cancel out the noise would not be 100% effective. The parallel twisted cores of Starquad mean that each pair of cores sits the same distance from the problem source so will induct at the same rate, making the noise cancellation much more effective. This cable is ideal for environments where electrical circuits are in high use, long cable runs and for musicians who want uncompromised results.
