View Full Version : Exposure Vii pre-amp hum on mc input
Hi, when selecting mc on this pre-amp there is a low frequency hum coming from speakers. When selecting other inputs there is no hum, what could it be?
I'm using an ortofon mc25e cartridge and ar eb101 turntable
thanks

My first thoughts are "what's it sitting beside?" MC stages sometimes pick up hum like velvet attracts fluff. I had a similar problem when siting a DAC near my preamp

I would check the tonearm grounding wire first. Is your tonearm grounding wire connected to the ground / earth terminal on the preamp?
