Hi guys,
I'm developing a portable preamplifier for dynamo mic Phantom powered, with a 75Hz filter and polarity inverter. Since I have a single ended output, I need to balance the output and I want to use a transformer. I've came across the OEP and I've seen it has been already discussed in this forum. You think that the 600:600 version a262a7e should be fine for the purpose?
The amplifier stage is realized with INA849 and the filter with OPA1692. In open loop configuration the OPA has an impedance of 2Ohm and the INA under 1Ohm in audio bandwith.
