NPO, no big deal, I was taking time off of Metallica and playing my newly acquired Mustang anyways.
I really appreciate the detailed response, it didn't work in my situation, but it did get my wheels spinning! Before changing any adjustments on the EQs I turned the game volume all the way down and noticed the white noise sound didn't change. I ended up goofing around with the EQ settings and figured out what was causing my noise was the very last two EQ adjustments on the right for the backbox speakers, in particular the last one on the right was very sensitive and controlled most of that noise. So after experimenting for a little while what I ended up doing was with the game in attract mode I adjusted the last two for the amount of white noise I considered tolerable and didn't get on my nerves, then I turned the game volume up pretty loud, 50 I think? I played a song using the jukebox feature. I left the last two settings on the right alone and adjusted all the other EQ setting to the sound I liked the most.
I do have to say I'm a little disappointed that I couldn't turn the last two up much because to me they add to the way I like the audio to sound, but that white noise REALLY got on my nerves to where I didn't want to play the game or even have it turned on. I was talking to Metallik last night at his get together about this and he and I were trying to figure out where the EQ was picking up the sound at, was it off the power supply, at one point he suggested using a in-line filter, which I think would be worth trying, is it a very sensitive channel on the EQ or I was wondering if maybe just the audio feed from Stern isn't super clear and the EQ picks it up and amplifies it?
