Warm Audio WA73-EQ Single Channel Microphone Preamp EQ

Professional engineers have relied on '73-style preamps to shape the sound of countless pop and rock records, and the Warm Audio WA73-EQ delivers that legendary British tone with meticulous attention to authentic vintage design. This single-channel Class A microphone preamp with EQ represents years of careful reverse-engineering and countless hours of auditioning to recreate the sweet character and unique sonic signature that made the original units so coveted in studios worldwide.

The WA73-EQ features genuine UK-made Carnhill transformers, faithfully reproducing the early versions that engineers prize for their fluid, forgiving nature and beautiful saturation characteristics. Warm Audio has maintained circuit integrity by using tantalum and polystyrene capacitors in the signal path, along with carefully selected output transistors that provide smoother performance at high gain settings. The complex dual concentric EQ switches are manufactured by Blore Edwards in the UK to military specifications, ensuring reliability and precision.

With 80dB of gain through a fully discrete, hand-wired signal path, this preamp excels with all microphone types across vocals, instruments, and full mixes. The comprehensive 3-band inductor-based EQ offers extensive frequency control, including additional high-band points beyond the vintage 1073 design. A 4-position high-pass filter, tone button for transformer impedance switching, and multiple input/output options make the WA73-EQ equally suited to studio recording and live applications.
