## Long description

The Warm Audio WA273 is a dual-channel '73-style microphone preamplifier designed to reproduce the classic British preamp tone used on countless pop and rock records. Built as part of the WA73 Family, the WA273 combines a fully discrete Carnhill Transformer balanced signal path with up to 80 dB of gain, a frequency response useful for recording (20–20,000 Hz), and an input impedance of 1200 Ω. The unit is hand-wired and hand-assembled and is suited for both studio and live applications where a musical, vintage-style coloration is required.
Advantages
The WA273 uses custom UK Carnhill transformers chosen to reproduce the early, highly sought-after '73-style tonal character: smooth saturation when pushed and a musical midrange presence. Its signal path employs tantalum and polystyrene capacitors and a selected output transistor to retain a smoother high‑gain response consistent with early British designs. Hand wiring and hand assembly maintain build integrity and contribute to the unit’s classic sound while offering up to 80 dB of clean gain for a wide range of sources.
Suitable for
Recording vocals with vintage-style warm coloration
Tracking acoustic and electric guitars
Amplifying bass, drums and percussion
Recording orchestral and keyboard sources
Using as a tone-shaping insert for mixes or submixes

How to use
Connect your microphone to the WA273 input and route the balanced output to your interface or mixing console. Set the gain to achieve the desired level without clipping, using the unit’s high gain range for low-output microphones or to add harmonic saturation. For cleaner tracking, keep gain moderate; to impart vintage coloration or gentle saturation, increase gain while monitoring levels. Use the unit as an insert on mix buses to add coloration to submixes or final mixes as needed.
Usage recommendations
For a classic '73-style sound, pair the WA273 with condenser or ribbon microphones for vocals and acoustic instruments, and with dynamic mics on louder sources; experiment with gain to taste—lower settings for transparency, higher settings for musical saturation.
