Warm Audio WA73 – iconic microphone preamp with tube EQ, faithfully emulating the legendary Neve 1073 design. Delivers warm, saturated sound with rich harmonics, ideal for vocalists, guitarists, and sound engineers. Built with premium components including Carnhill transformers, provides authentic vintage warmth in a modern build. Compact enclosure with wood end caps (114 x 241 x 89 mm, 2.7 kg) versatile for studio or portable setups.
WA73 uses discrete Class A circuitry with three 12AX7 tubes, Carnhill input/output transformers, and 80 dB gain with low noise (EIN -127 dBu). Adjustable impedance (300/1200 Ohm) optimizes for various mics, switches for PAD (-20 dB), +48V phantom, and HPF (50-300 Hz) offer control. EQ section with high (3.4/7.2/10.7/12 kHz), mid (0.36-7.4 kHz), and low (35-220 Hz) bands adds character. XLR and TRS line outputs ensure pro gear compatibility.
As a tribute to the classic 1073, WA73 blends vintage mojo with reliability, adding depth to DI or vocal recordings. Hand-soldered point-to-point construction guarantees top quality.
