[QUOTE="Steve Tarak, post: 1788, member: 109"] One of the groups I mix utilizes an Allen Heath for in ear monitoring. A problem has developed with the phantom power on one channel. The stage mics are hard split to me and a Presonus 24 and I noted at a Wednesday show a crackling / sizzling on this channel. We isolated this to the phantom power button on the AH. When depressed, the channel would exhibit 40 to 50 hz hum, sizzling and cracking sound. I bypassed the split snake, went direct to my board and finished the show. This buttom is constantly on, it does not get turned on and off and we've had no issue for more than a year. What anomolies can happen w/ phantom power? Can they cause any crap out of another mixer channel, be that Presonus, or other? I've had phantom fail all together, but not this symptom. Appreciate any input. thanks, Steve [/QUOTE]
