Re: Voltage vs capsule size, type, etc.
OK, from the photos, we can see what you have to work with. #1 - 25mm electret capsule. These will work without a polarization supply. Referred to as "CM-012" on some AliEx listings. Good value for

Re: Voltage vs capsule size, type, etc.
James the first capsule, 25mm most likely is electret, meaning it does not need bias voltage. The second one, 34mm does. To your comment on the BM-800. Not sure people replace just the board and leave

Good Morning Gentlemen! To Jules -- I follow the gist of your commentary. Obviously I need to learn more about polarizing voltage versus phantom power. I would appreciate leads to the homework I must

Re: capsules for close micing drums - suggestions?
well my dynamic capsules arrived, but they have a DC resistance of 622 ohms- so not what you were recommending. Can't really complain since the listing didn't actually specify the impedance. I guess

Re: Voltage vs capsule size, type, etc.
That seller offers two configurations. The one called "Front panel" is for use with electrets like most 25mm capsules. These do not require polarization voltage. The second offering is "Front panel

A photo showing how you have connected the capsule to the board(s) would also be helpful.

I'd need to know exactly what the 25mm capsule is. A link or picture would be good there. Do you understand the difference between an electret and an externally polarised capsule? Your 34mm capsule

I can¡¯t speak to the eBay board but I designed the OPA circuit. There are two things going on here. One is the impedance converter and balanced line driver part of that circuit. It does what the

By way of clarification - the 25 mm capsule works well with the subject board, the 34mm capsule does not. Thanks ! JHR

Something else is going on. The description is jumbled. What is a "condenser driver board" (60v or otherwise) are we talking about a polarisation voltage generator or something else? 60v is probably

Good Day. So, let's stipulate I tried to match an inexpensive 60v condenser driver board with first, a 25 mm condenser capsule, and second, a 34mm condenser capsule ... and the results were vastly

Agree with Matt as well. Also more sensitive to plosives but that¡¯s an edge terminated thing. It¡¯s the falling off at 10k that deterred me. Best Regards, Jules Ryckebusch

Re: JLI-3412
As you say, no intrinsic reason for an electret to be noisier than a 'standard' condenser... I think I may have confused the issue by comparing? a 25mm electret with a 34mm LDC. Slight case of my

Re: JLI-3412
The 3412 has more bass and/or more proximity than the TSB-2555; the 2555 is actually somewhat thin on the bottom end as compared to LDCs. The 3412 flatter on top than the 2555, but the response falls
