I've had to replace a FET in one of a once matched pair of phantom powered mics. We're not too worried about any difference in gain as that can be balanced off on the mixer. But is there more noise compared to its fellow? The only mixer I have around with 48V and balanced feed mic inputs has a fan in it. However I wrap the mics I hear/measure the fan noise. Long lead and I get mains hash/hum pick up. Looks as though I'll have to go inside the mixer and temporarily cut the fan. Any other ideas or what to place the mics in that is as acoustically dead/mechanically non-transmissive ,that I can conveniently find laying around
