Warm Audio WA-84 Small Diaphragm Condenser Microphone (Nickel)

Reproduction of a Classic

The Warm Audio WA-84 is a precise reproduction of the industry standard KM84 circuit. The WA-84 is a fully discrete, transformer-coupled small diaphragm condenser perfect for professional studios, home studios, live sound, and broadcast. The WA-84 excels across a wide range of sources including drums, acoustic guitars, percussion, piano, strings, brass, woodwinds, and more.

Transformer Coupled

Like the original vintage units, the WA-84 delivers open clarity with strong noise rejection. Unlike modern reissues that skip the transformer and “update” the circuit, the WA-84 stays true to the vintage design. Featuring a heavy nickel CineMag transformer in the signal path alongside audiophile grade Wima capacitors and a Fairchild FET, the WA-84 delivers a smooth top end and a beefy mid to low end that modern transformerless designs don't replicate.

The Sound

The class-A circuitry, CineMag transformer, and meticulous design capture precise detail with great isolation, and the slight 8-10kHz dip and 11-20kHz presence bump smooths out harsh highs without any lost brilliance. The cardioid capsule is replaceable and easily unscrewed from the body, and a -10dB pad handles loud sources up to 133dB SPL.

Industry Reviewed

From Sound on Sound: "The WA-84 sounded very close to the KM84s on- and off axis, and in many cases, I doubt I'd have been able to tell the difference in a blind test"
