Shields and Grounding Galen Gareis, April 17, 2020August 4, 2020 BACKGROUND: There is always discussion on how to ground a shield. The answer lies in what the worst-case noise situation is. It isn’t always the same answer. Do you leave one end open or ground both ends? If you ground only one ends, which end? We can look at how… Continue Reading
XLR SHORT REACH ORIENTATION Galen Gareis, November 11, 2019May 15, 2023 I have four 1 meter XLR sets going from the bottom component, up to the pre amplifier component. The natural LOOP needs to be allowed to form, unobstructed from the rear wall. This takes about 12″-13″ of clearance from the back of the unit to the wall. The rack may… Continue Reading
TIME… Galen Gareis, August 22, 2019 If you have spent plenty on cables you may well wonder WHY these cables are physically as they are. If care is taken to adhere to fundamentals, there are very good reasons for a physical design in audio cable, of both high (interconnect) and low (speaker) input impedance types. If… Continue Reading
Shields and Noise Cable Dynamics Galen Gareis, August 20, 2019 We tend to believe that SHIELDED cables are superior to UNSHIELDED cables but the opposite is true from a signal transmission evaluation. Why we feel SHIELDED is better is because we overestimate NOISE ingress (outside the cable into the cable) environmental issues. Cable electrical is determined by the primarily REACTIVE… Continue Reading
