Warm Audio WA273
The Warm Audio WA273 is a two-channel mic, line, and instrument preamp inspired by the legendary 1073 circuit that defined the punchy, larger-than-life sound of classic rock and countless studio recordings. Designed for engineers who want bold tone with real character, the WA273 delivers a rich low end, focused mids, and a slightly resonant top that helps tracks feel finished right from the start.
Built with fully discrete Class A circuitry and UK-made Carnhill transformers, the WA273 offers up to 80dB of gain, making it equally comfortable with condenser, dynamic, and low-output ribbon microphones. From subtle warmth to driven harmonic color, it gives you control over how much attitude you want in your signal.
As an authorized dealer, Pro Audio Reserve ensures you receive a genuine Warm Audio preamp backed by full manufacturer warranty and long-term support.
Warm Audio WA273 Overview
Classic British Console Tone, Refined for Modern Studios
The WA273 is built around the sound engineers have chased for decades. Its transformer-balanced signal path delivers weight and presence that works beautifully on vocals, drums, guitars, and bass. Push the input stage and pull back the output for added saturation, or keep it clean for confident, open recordings.
Having two matched channels makes it ideal for stereo sources, drum overheads, keys, and bus processing when you want cohesive color across a pair of tracks.
Flexible Gain Staging and Mic Optimization
With up to 80dB of gain available, the WA273 handles everything from whisper-quiet ribbon mics to hot condenser signals. Resistor-stepped rotary gain switches make recall simple, while the output level controls let you fine-tune how hard you drive the circuit.
Switchable input impedance allows you to optimize the response of different microphones or subtly shift the tone to better suit the source.
A Serious Front End for Any Recording Chain
The WA273 includes mic, line, and DI inputs on each channel, along with inserts for integrating compressors or EQs directly into your signal path. Polarity switches, phantom power, and inductor-based highpass filters give you practical control during tracking.
Whether you are recording a full band or shaping individual sources, the Warm Audio WA273 quickly becomes a trusted centerpiece in the rack.
