The Audio-Technica MB4K is a cardioid condenser microphone from the Midnight Blues series — a studio-quality solution ideal for vocal and instrument recording. It offers dual-power operation (phantom or battery), making it versatile enough for both studio sessions and live or mobile use. Built with rugged all-metal construction and a soft-touch finish, the MB4K delivers reliable performance while minimizing mechanical noise and ensuring a comfortable grip. Its extended frequency response and condenser design yield smooth, natural sound, while the corrosion-resistant gold-plated XLRM output connector ensures stable signal transmission. An easy on/off switch adds simple control on the go. The package includes a stand clamp (for standard mic stands), a battery, and a protective pouch — making the MB4K a ready-to-use, flexible mic for vocalists, instrumentalists, and recording setups.
