RSR534 - Derek Bargaehr - The Nerdy Mic Episode You Didn't Know You Needed!

November 28, 2025·1 hr 6 min·6 clips

Derek Bargaehr reveals how he modernizes classic tube mics like the AKG C12 with variable voltage and voicing switches.

The clip starts in mic land. Once the sponsor read clears, the conversation settles on XY small-diaphragm pairs for acoustic guitar and the appeal of instant phase coherence. That tidy stereo image is the hook. The point is not chasing novelty, but having a setup that can cut down on measuring, second guessing, and drum-overhead fuss. Then the pad question opens up. The guest explains why modern preamps may put a 10 or 20 dB pad before an input transformer, which changes what gets driven and how hard. The host catches the surprise as it happens. Microphone pads are not only about raw level, especially when transformers or onboard electronics sit in the path. That is where the episode gets fun. Instead of brushing past the technical bits, the host says the Rockstars like hearing what is actually happening inside the gear. The guest keeps it plain. Pads are a relationship between the electronics inside the microphone and the electronics at the other end, especially with transformerless, tubeless solid-state designs. The exchange stays loose too. A bumped microphone turns into a quick laugh about editors, so it still feels like two engineers leaning over a console. The V4 Gen 2 gives the idea something concrete, with 10 and 20 dB pad options and the image of a condenser microphone inside a kick drum. That example makes the theory easier to feel. The source is loud enough that pad behavior stops being a spec-sheet detail and starts behaving like a real studio choice. For engineers who already speak in mic models, pads, transformers, and preamp choices, the payoff is hearing familiar terms tied back to cause and effect.
