I've seen several requests online for the CMC6 schematic over the years.. but never seen one posted? However, I have seen a couple of forum comments that suggest that the CMC6 schematic is almost

Would that be the perfect choice in a Schoeps circuit with such low Ciss?

Question: why are you getting the ground for the preamp circuit from the headphone output? My instinct would be to pick up the preamp ground from the following mic input, and to keep the headphone

Hello! I have the Schoeps CMC6 body (with MK4 capsule) that’s much noisier (15-20 db more noise) than others. I’ve checked and it’s not the capsule, cabling, preamps etc. ?I’m dead sure

Making it flat is not too difficult, but making it both differential and flat is probably impossible.You need two preamps connected to a differential amp. That would require two dual opamps (4 stages

Thanks Jerry, I wanted some gentle bass roll-off,? to try to trim any low-frequency engine noise. However it does (did!) sound more tinny than ideal. On reflection bass roll-off will probably

Sounds like motor-boating, a relaxation oscillation that happens at low frequency. I guess one of the reasons is that the supply voltage is not regulated enough. With 12V incoming voltage, the voltage

I've added a link to imgur. Right click and open the image in a new tab to see full size. I've also added it as an attachment rather than an inline here.

Can you provide a more legible schematic? <michaeljtbrooks@...> wrote:

Hi All, Can you help me troubleshoot the cause of failure of this OPA1642 based circuit? The design intentions: * Bias power is tapped from the comm radio (8-15v), which comes from the comm radio's

What are you actually trying to achieve? There's lots of pitfalls in my suggested circuit. It isn't a tried and tested project, and will almost certainly require revision and troubleshooting. I

Hello Yes I meant this circuit. I a near future I will try to built it more or less as you sudgested it : a single opamp but with three capsules for each sides. What do you mean by a simpler

I take it you mean this? https://halfshavedyaks.xyz/forumimages/4mic2chanV3.png I'd completely forgotten I did that! It was never built, whoever was asking for it never got back to me I think. If

Hello, sorry for the topic revival As an accordion player I am really interested in this project. I was wondering what would happen if only one of the two XLR is connected? thank you. This is a really

If you have a look at Siegfried Linkwitz's site, there is an alternative method of using that microphone here https://www.linkwitzlab.com/sys_test.htm#Mic Craig

Thank you I forgot to mention that I want to put it inside an instrument. That's why I would like to have control of the volume.

This is basically unity gain and going into a mic preamp. That’s the best place to adjust the gain Best Regards, Jules Ryckebusch

Hi everyone, I'm working on a circuit to control the power supply and mute function of a phantom-powered condenser microphone. The general concept is mostly in place, and I’d love to get your

Hello, I build this preamp and I was wondering if there is a way to control the audio volume? My best guess so far would be to add two capacitors beside C3 and C6 and wire a dual pot. But it seems

:) As Jerry Lee said, the OPA1655 could be the closest to the specs: 4nV√Hz @1kHz, and 2.9nV√Hz @10Khz. 3.9mA quiescent current, and it also has low distortion. Here is the Vn graph, from the
