SP C1 part, what is it??

[Angusdevil]

I opened up my C1 today so that I could fix a small dent in the screen that was bugging me. When I was looking around the electronics, I noticed a small 1/4" x 1/4" blue box with a screw on top, then covered in glue or wax. Kinda looked like a trim from something but for what? Does anybody know what this does and what it controls??

Here is a pic from a website that is of a B1 and B2 and it appears that the B2 has the same blue box.

There's only one way that you may get an accurate answer and that is to contact PMI/SP themselves.

ausrock is correct... for Studio Projects mic questions and problems you need to go to http://www.studioprojectsusa.com/tech.html and PMI Audio will help you with all your Studio Projects mic problems.

Arent those pics of Behringer mics?

[Leeking]

I have quite a obvious dent on my C1 screen as well when I received it....

But I'm too far away(Malaysia) to do something about it....

But the mic sounds good... so it doesn't bother me too much.

It's a variable resister for adjusting the bias voltage of the input FET.

Ya those are Behringer mics, but both the Behringer B1, B2 and SP C1 are made by 797 and so some of the parts maybe the same and in this case, I do believe that they maybe the same.

Does anyone else have any info on this little blue box?? I've emailed Studio Projects and am waiting for a reply. I was kinda hoping it would control where the bass roll off was or maybe how strong the pad is or something like that. Not that I really want to change my mic, I love it, just thought it would be cool to have another option with it.

Just got an email from Studio Projects this morning and this is what they said...

"The small blue box on the C1 circuit board is indeed a trim control. It is used to adjust the gate feedback bias for the input FET."

I guess that answers my question fairly well. For the time being, i'll just leave it alone, sounds more or less like something that I wasn't ment to mess with yet (maybe thats why it was covered in glue.....)

good one, FPicker

Flatpicker had already answered you.

[Angusdevil]

Thanks FlatPicker for the info.

I thought I would just post what SP sent me anyway since I had just got it.

Go learn to play an instrument or something and leave me out of this... most everyone already knows what I think about Studio Projects and Behringer.

No prob. I just happen to know what that one was.

Fixing a dent in the top windscreen is easy, as long as you are careful. To do it, remove the bottom three screws, then the three screws holding the headgrille on.

Find a scredriver that has a handle at the end that is shaped like a small ball. Some Craftsman #2 Phillips screwdrivers have good handles to do it with. Now, depending on if your right or left handed, cup the palm of you hand around the top of the head grille with the opening of the headgrille facing up.

Now what you need to do is insert the ball side of the handle on the screwdriver into the head grille, for me I use my right hand while cupping the grille with my left as I am a righty. At the same time put equal amount of pressure on each area of the grille you wish to push into shape, while at the same time, apply back pressure from the palm off your hand up, while you apply down pressure from the ball side of the screwdriver. This will prevent the grille from coming off and allow you to bend it into shape.

DO THIS IN SMALL AREAS SLOWLY. You do not want to apply to much pressure with the handle of the screwdriver so you push the grille off. Just use enough pressure to slowly roll the ball around the grille to smooth the dent out while in your hand. This works great if you take your time, and do it slowly with just enough pressure to get the job done. It may not be perfect, but it works.

When back into shape, put the headgrille back on with the screws, and then the body. Align the body so the switch is set correctly on the rear of the mic so you can move it to all three positions.

That is all you have to do... Of course we are happy to do it for you if you send it in. If you screw it up real bad, we can send you a new headgrille.

That is exactly what I did and it worked wonderfully

Behringer doesn't use this mic forum to sell people on customer support.

Behringer and Studio Projects customer support...

DJL - C'mon, even you have to admit that SP provides great customer support. Regardless of what the opinion is about their products, they stand behind them 100%. I've seen that documented here and other places numerous times. I've heard and read horror stories about Behringer support, shipping back to Germany for repairs, months long delays in returns.

Are we now so much on the lookout for spam that a vendor can't even offer support advice?

That's probably because they don't have any for sale.

I've considered a few ideas, but haven't had time to really dig in. I'll have more time this weekend. Ping me around Monday.

I'm sure both Behringer and Studio Projects customer service is just fine... and in most cases if you have a problem with a product from either, the store where you got it from will replace it... you don't have to send it back to to CA USA or Germany... lol. Both Behringer and Studio Projects are trying to bring the starving musicians low costing products and doing the best they can... I don't think there is any need to put one down in order to build the other up do you?
