Overview
Product description
The Warm Audio WA73-EQ is a single-channel, Class-A microphone preamplifier with an integrated 3-band equalizer , designed as a homage to the classic British "73-style" lineage (à la Neve 1073). It offers up to 80 dB of gain , transformer-balanced signal paths, and careful component choices to evoke that warm, musical analog coloration while adding flexibility via its onboard EQ section. Warm Audio positions it as a "modern, more affordable but sonically serious" take on the legendary British consoles - giving engineers and studios a tool that blends character and utility. Key Features & Specs Here are the standout features and technical specs: Feature Details Gain / Topology Up to 80 dB of gain (stepped resistor gain knob) Circuit Style Discrete Class-A design, fully discrete signal path, transformer-balanced Transformers Custom-made Carnhill transformers (UK) for input and output EQ Section 3-band inductor-based equalizer (low, mid, high) LF (Low Frequency) Boost/cut at selectable points: 35, 60, 110, 220 Hz Mid Frequency Boost/cut at: 360, 700, 1.6k, 3.2k, 4.8k, 7.2k Hz HF (High Frequency) Shelving options at 10, 12, 16 kHz High-Pass Filter 4-position HPF: Off, 50, 80, 160, or 300 Hz Additional Controls • Tone switch: changes input transformer impedance (e.g. to add "air" or match different mic types) • Polarity (phase) invert switch • Phantom power (48V) • Ground lift • Insert send/return (TS jacks) for external processing Inputs / Outputs • Mic input (XLR) • Line input (TRS) • Instrument (front TS) • Insert send/return (TS) • Line outputs (XLR, TRS) Metering / Output Control Output level knob; 5-segment LED meter for level monitoring Rack / Form Factor 1U, 19" rack-mountable unit Power / Build IEC input, switchable 115/230V, rugged steel chassis, hand-wired and hand-assembled Frequency Response / Noise ~20 Hz to 20 kHz with tight tolerances; very low noise floor (specs in manual)
