Pin 1 Problem Modern examples of an ongoing grounding issue neil has observed that most rf interference to audio equipment is caused by a pin problem, and some recent research i’ve done has convinced me that he’s right. Learn how a common equipment design error causes rf interference in audio wiring and equipment. see examples of mic and line level products with the pin 1 problem and how to fix it.
Xlr Pin 1 Problem At Charles Lindquist Blog Now that the audio engineering society has adopted the "pin 2 is hot" standard, the question of what to do with pin 1 is being addressed. a recommended practices document is being created covering interconnection of professional audio equipment. So what to do if you’re a user and you have a box with a pin 1 problem wired to an aes48 compliant product? the best solution of course would be to open the faulty box, disconnect pin 1 from the circuit board and connect it to the chassis with the shortest possible wire. Neil muncy called our attention to the pin 1 problem (the improper termination of the shield of audio wiring to the circuit board rather than to the shielding enclosure) in his classic 1994 paper, reprinted in the june 1995 journal of the aes. Learn about the causes and solutions of the pin 1 problem, a common source of humming, buzzing and noise in audio systems. find links to papers, articles and resources by experts in the field of emc, emi and grounding.

Learn about the causes and solutions of the pin 1 problem, a common source of humming, buzzing and noise in audio systems. find links to papers, articles and resources by experts in the field of emc, emi and grounding. Many audio engineers believe the pin 1 problem is the culprit of various emi emc problems in audio. namely, the pin 1, shield, of an xlr connector, is often connected to the circuit ground on the pcb. Considering i have read about the pin 1 problem i can't manage to turn the understanding into a solution. i am aware that the hypex nc modules have the ground from the module to the male clip on the xlr, while pin 1 is connected to chassis ground. Using the hummer to inject 80 to 100 milliamperes' worth of half‑rectified ac into the shielding — via pin 1— one can listen as well as look for pin 1 problems. After a bit of struggle we finally solved a hum problem that only a few of our balanced preamp customers were having with our ldrxb models so we wrote up a brief article on the subject of the dreaded "pin 1 problem".
