I’ve been trying to optimize performance of my new upcoming Mic Preamp Kit, the NK-72DI. It’s hooked up on my workbench to various probes and meters, and displays. I want to make sure that performance of this new Mic Preamp will be top-notch, and something my customers will be proud …
Just testing some PEQ-503 EQs before shipping out to customers. Each frequency band has two (2) selectable frequencies, and a bypass switch.

Hello folks! I’m currently working and testing a new mic preamp kit as successor to our SK-1DI 500 Series Mic Preamp Kit. I’m calling it our NK-72DI. This new mic preamp will feature Carnhill transformers, imported from the UK – the same kind of transformers used in Neve preamps and …
An opamp doesn’t know where the “Ground” is, so one can normally operate an opamp from a dual power supply (i.e. also called split power supply, dual power supply with +/-V supply voltages) or from single-supply voltages (V+ & Gnd). As long as you don’t exceed the Maximum Ratings specified …
So here’s the scenario… you have a power transformer with a voltage output of 25V + 25V AC. Let’s say, you’re using this power transformer to supply power to a power amplifier project. So it’s all good. But you also need 5 Volts DC to power some logic circuits (a …
