Overview

The AKG P420 is a large-diaphragm true condenser microphone designed for project studio recording where versatility matters. Its one-inch dual-diaphragm capsule supports three polar patterns — cardioid for focused vocal and instrument capture, omnidirectional for room ambience and ensemble recording, and figure-of-eight for face-to-face interviews or mid-side stereo techniques. This flexibility makes it a practical single-microphone solution for studios that handle a wide range of recording tasks, from voice-over and singing to grand piano, woodwinds, brass, and percussion.

The P420 features a transformerless output circuit that keeps self-noise low while delivering a wide dynamic range. A switchable -20 dB attenuation pad lets it handle sound pressure levels up to 155 dB without distortion, and a bass roll-off filter helps tame low-frequency rumble and proximity effect. It connects via standard balanced XLR output and requires 48V phantom power. AKG includes a spider shock mount for vibration isolation and an aluminum carrying case for protection, making the P420 a well-equipped package for serious recording on a project studio budget.
