## Long description

The Warm Audio WA273-EQ audio preamplifier Black 20-20000 Hz 1200 Ω is a dual-channel '73-style mic preamp with onboard equalization, designed to reproduce classic British preamp character for studio and live applications. Covering a frequency range of 20–20,000 Hz and offering an input impedance of 1200 ohms, the WA273-EQ provides up to 80 dB of gain through a fully discrete, transformer-balanced signal path. The unit is hand-wired and hand-assembled, uses custom UK Carnhill transformers and high-quality capacitors, and accepts mains power at 115/230 V.
Advantages
The WA273-EQ combines vintage '73-style tonal character with modern build reliability. Custom Carnhill transformers deliver a smooth, musical saturation when pushed while preserving clarity at lower levels. Tantalum and polystyrene capacitors in the signal path and a carefully selected output transistor contribute to stable high-gain behaviour and refined top-end response. UK-made Blore Edwards dual-concentric switch potentiometers ensure accurate and durable EQ control. Hand-wired construction supports consistent signal integrity and serviceability.
Suitable for
 Recording vocals with classic British preamp colouration
 Tracking acoustic and electric guitars
 Reamping or tone-shaping mixes and instruments
 Capturing drums, percussion and bass sources
 Use in live sound rigs and project studio setups

How to use
Connect microphones or line-level sources to the appropriate inputs and route outputs to your interface, mixer or console. Set input gain using the preamp gain control while monitoring signal level to avoid clipping; the WA273-EQ provides up to 80 dB of gain for low-output mics such as ribbons. Use the onboard EQ to shape tone—apply gentle boosts or cuts and listen for interaction between bands. When pushing the preamp for harmonic saturation, raise the gain and adjust output or pad as needed to maintain optimal levels in the downstream chain. Switch mains voltage as required for your region and ensure proper grounding.
Usage recommendations
For a classic '73-style character, combine the WA273-EQ with condenser, dynamic, or ribbon microphones and use moderate gain to capture warmth and presence. Use the EQ conservatively to preserve natural timbre: small adjustments often produce musical results. For more saturated tones, drive the input harder and compensate output level downstream; when tracking ensembles, set conservative gain staging and fine-tune EQ for separation. Regularly check wiring and pots for maintenance due to the hand-wired design.
