First off, thank you for this website for the wealth of info I've gathered over the last two days. Quite a resource to have.
I purchased a four channel pm1000 pre over at the tapeop message board. The seller is not the person who put this together so they've not been able to help me out with some (probably very stupid) questions.
After talking with someone and researching on here, I've learned that the master modules have three different amps on them, two of them of the same design from the third. These amps are also similar to an input module, hence why they can be used as pres.
I've run some signal through them, bass guitar, mic'd with an re20. Sounds great. Here's my question, and it seems like it shouldn't be a question, and perhaps my amount of weed intake is the reason why I keep flip flopping on my findings. The two pots for each channel are not marked "input" or "output". Should be pretty easy to figure it out right? well, not so much. Seems they BOTH react very similar. I'm used to other preamps where I set the output wide open and dial in my input gain… and if i'm wanting more "color" from the input gain, I turn down the output, allowing me to open up the input more.. Well, on this set up, both knobs seem to "push" or distort in a very similar matter. Not sure if its because I'm hitting the output transformers and/or input transformers similarly depending? Seems I get the "cleanest" when both pots are around 12:00.
This very much is a "use your ears, make a decision, hit record" situation, which I'm fine with.. but I'm also wired a way where I need to know how and why before I can go with that. These photos are all I have right now, and I'll post more if these are obviously not enough.
Thank you.
