Re: Recommended operating voltage for TSB 2555


 

Sadly, the 2555 data sheet you link to is mostly nonsense.? This capsule is a FETless electret, and the data sheet has details of the characteristics of the impedance converter shown in the schematic -- which doesn't exist within this capsule??
(The 2555 capsule only contains the part shown within the dotted line box on the schematic)
So, although you don't need a polarising voltage - as recordinghacks has already indicated - you will need an impedance converter.? That can be a Schoeps style FET interface, or perhaps an op amp impedance converter?
Mic Scharf has already linked to my Mid/side project . The FETless version of that project? shows how you might interface a capsule like the 2555, in it simplest form.
And it will be the capsule noise itself which dominates with that circuit.

Hello!

Back in the mic making game and working on a Mid-Side setup! Anyways, I bought several TSB2555 capsules and looking at the datasheet it says the operating voltage is 1-10V (). Seems like a big range...any recommendations of what voltage to get the lowest self noise and highest SPL? Lowest noise matters most to me. Also can the TSB2555 be used in a Schoeps style circuit? I assume so but would like to verify.?

Thanks!

Best regards,
Blair
