Warm Audio WA273-EQ 2-Channel 1073-Style Console Preamp with 3-Band EQ

Warm Audio WA273-EQ: A Complete British Console Channel Strip

The Warm Audio WA273-EQ is a two-channel British console-style channel strip that combines the acclaimed 1073-style preamplifier with a matching 3-band equalizer on each channel. It marries a fully discrete, pure Class A preamp path to genuine Carnhill transformers, then hands you the same musical tone-shaping controls that made the original console EQ legendary. With two full channels, you can equalize a stereo pair identically or shape two different sources at once, all before the signal ever reaches your converter. Up to 80 dB of gain covers everything from quiet ribbons to hot condensers. Shaping tone at the source, rather than fixing it later in software, is how classic records earned their finished sound on the way in. The WA273-EQ brings that entire front-end workflow into a single 2U rack space.

Why Equalizing at the Source Matters

Recording through an equalizer before conversion means the tonal decision becomes part of the captured performance rather than a repair made afterward. Analog EQ interacts with the discrete Class A preamp and its transformers, so boosting a band also engages the harmonic character of the circuit for a richer result than a clinical digital filter. Committing to a sound early frees you from second-guessing every track later and encourages faster, more confident mixing. The console-style bands here are broad and musical, designed to flatter a source rather than surgically correct it. That is precisely why engineers reach for a channel strip to track vocals, bass, and drums. The WA273-EQ lets you make those decisions with your ears, at the moment of performance.

Inside the 3-Band Console Equalizer

Each channel carries a three-band equalizer modeled on the classic British console tone stack. The low and high bands are shelving filters offering up to 16 dB of boost or cut, ideal for adding weight underneath a source or air and sheen on top. The midrange is a fixed-Q peaking band with selectable center frequencies, the range where presence, body, and the character of most instruments live. Blore Edwards dual-concentric controls let you choose a frequency and dial its boost or cut from a single stacked knob, keeping the front panel fast and intuitive. Because the EQ sits inside the same discrete, transformer-coupled path as the preamp, every move carries the circuit's analog signature. It is broad, forgiving, and endlessly musical rather than clinical.

Preamp Tone Control and Inductor Filter

Beneath the equalizer, the WA273-EQ keeps every tone tool that makes the preamp so flexible. A switchable input impedance tone control toggles between 1200 ohm and 300 ohm, loading the input transformer to shift between an open, clean voicing and a thicker, grittier one. The inductor-based high-pass filter sweeps 50, 80, 160, and 300 Hz at 18 dB per octave to remove rumble and proximity buildup smoothly before it hits the EQ. Using the filter first, then the EQ, gives you a clean canvas to shape without muddying the low end. A per-channel insert and ground-lift switch round out the routing for demanding studio setups. These controls turn a great-sounding preamp into a genuinely complete tracking front end.

Full I/O and Studio Integration

The WA273-EQ connects to any modern or vintage rig without compromise. Each channel provides XLR microphone inputs, line inputs for coloring existing tracks, and a front instrument DI for plugging in a bass or guitar directly. Balanced XLR and TRS outputs feed interfaces, patchbays, and mixers cleanly, while switchable 48V phantom power supports condenser microphones per channel. The insert point lets you patch a compressor into the chain between the preamp and the output stage. Two channels in a single 2U chassis keep a rack tidy while doubling your tracking capability. Whether it anchors a hybrid mix setup or serves as the main tracking path, it slots in effortlessly.

Who the WA273-EQ Is For

The WA273-EQ is built for engineers who want to commit to finished, console-shaped tones as they record, across two channels at once. Vocalists gain a present, polished sound with high-shelf air and midrange focus dialed in on the way in. Drum overheads, room mics, and stereo instruments benefit from identical EQ across a matched pair, while bass and guitar DIs get the weight and grit only analog shaping provides. It is the natural choice for a producer building a boutique hybrid studio or a professional room wanting classic console color without a full desk. From tracking dates to mix-bus coloration, it delivers a sound that has anchored hit records for generations. It is a channel strip you will keep patched in for years.
