Warm Audio WA273-EQ
The Warm Audio WA273-EQ is a two-channel mic, line, and instrument preamp with classic British EQ, inspired by the legendary 1073 designs that shaped the sound of ’70s rock and generations of recordings that followed. Built for engineers who want unmistakable tone at the source, the WA273-EQ combines bold preamp character with musical, inductor-based equalization in a single, cohesive unit.
With up to 80dB of gain and a fully discrete, transformer-balanced Class A signal path, the WA273-EQ delivers a harmonically rich low end, focused midrange, and open high frequencies that respond beautifully to gain staging. UK-made Carnhill transformers and premium components throughout ensure the sound stays authoritative and musical, whether you are tracking vocals, drums, guitars, or shaping stems during a mix.
As an authorized dealer, Pro Audio Reserve ensures you receive a genuine Warm Audio unit backed by full manufacturer warranty and long-term support.
Warm Audio WA273-EQ Overview
Classic British Preamp Tone with Built-In EQ
The WA273-EQ captures the feel and response of iconic British console channels, pairing a powerful mic preamp with a musical EQ section that encourages confident decisions during tracking. Push the input stage for added color, then balance levels with the output control for recordings that feel finished before they ever hit your DAW.
With two identical channels, the WA273-EQ is a natural choice for stereo sources, overheads, keys, and any application where matched tone matters.
Definitive 1073-Style Equalization
Each channel features a three-band, inductor-based EQ modeled after the classic 1073 topology. The low shelf adds weight and authority, the mid band lets you shape presence and bite, and the high shelf brings clarity and air without sounding brittle.
A selectable highpass filter helps control unwanted low-end buildup, making the EQ section just as useful for corrective shaping as it is for tone enhancement.
A Versatile Front End for Any Recording Chain
The WA273-EQ includes mic, line, and DI inputs on each channel, along with insert points for integrating compressors or other outboard gear. Switchable impedance, phantom power, polarity control, and LED metering make it easy to adapt to different microphones and recording situations.
Whether you are tracking through EQ on the way in or using it as a tone-shaping tool during mixdown, the Warm Audio WA273-EQ quickly becomes a centerpiece in the rack.
