First time post here, but I feel like I know lots of you just from reading many of the threads here!
For background, last year I built an LCR set of Overnight Sensations (MTM ones) that I ordered from Meniscus. I have read the PE Forums and almost every thread here at Mission Possible DIY over the past year, and so am beginning to understand a bit about the speaker side of things. However, the amplifier side is totally new to me.
Therefore, I honestly know next to nothing about electronics. So first, I want to make sure I don't zap myself, and second, that I don't fry the new equipment. I'm looking to learn a lot here and have downloaded quite a few articles from Elliot Sound to see what I can learn. However, getting to the practical side, I have attached my wiring diagram (currently incomplete) and have a few questions for the minds here:
First - The Sure manual says that the ground connection for the amp board needs to have the Positive of the -54V supply and the Negative of the +54V supply. On the Abletec manual, it only lists Pin1 and Pin2 as the -54V, and Pin5 and Pin6 as +54V. Is there a positive and negative to these, and if so, which is which?
Second - Grounding - How do I go about grounding the mains input, Abletec output, and the amp board (if I do such a thing) to the Chassis? Are there separate points for each, do they all go to one point?
Thanks all for taking a look and helping me out! I have a multi-meter, soldering iron, wire stripper, etc. I also have a few odds and ends like IEC power cable, IEC female connector, Power on switch. Anything else like do i put a fuse somewhere (and how would I do that), how do I wire the on/off switch, etc.
