Warm Audio WA73-EQ Microphone Preamp with EQ - Secondhand

Full Description

Classic British console sound

The WA73-EQ is modelled after one of the most legendary British console preamps, responsible for shaping the sound of countless classic recordings. It captures the warmth, depth, and harmonic saturation that made the original a studio favourite. With a fully discrete signal path, it delivers a true analogue character, making vocals, instruments, and mixes sound fuller and more polished.

Built around custom-designed Carnhill transformers, the WA73-EQ ensures authentic signal colouration, adding musical richness to any source. This makes it ideal for those who want to bring a professional analogue touch to their recordings.

Versatile 3-band EQ

The WA73-EQ’s console-grade EQ section allows for detailed frequency sculpting, making it easier to shape and refine your sound. The 3-band design includes low (35-220 Hz), mid (360 Hz - 7200 kHz), and high (10-16 kHz) controls, giving you precision over key tonal areas.

Using UK-made Blore Edwards potentiometers, the EQ provides smooth and accurate adjustments. Perfect for enhancing vocals, adding weight to instruments, or fine-tuning a mix; the WA73-EQ delivers professional-grade control over your sound.

High-gain preamp with flexible connectivity

With 80 dB of gain, the WA73-EQ can easily handle low-output microphones, including ribbon mics, without the need for additional boosting. This makes it an excellent choice for capturing everything from quiet acoustic performances to loud rock vocals with clarity and power.

The unit features multiple input and output options, including XLR, TRS, instrument, and line-level inputs. A switchable insert send/return allows external processing, such as compressors or additional EQs, before hitting the output transformer. This flexibility ensures seamless integration into any recording setup.

Built for professional use

The WA73-EQ is constructed using high-quality components and a hand-wired design, ensuring long-lasting durability and consistent performance. Each unit undergoes meticulous hand-testing and inspection by professional engineers and musicians at Warm Audio’s headquarters.

Designed for serious recording applications, this preamp offers a complete feature set, including 48V phantom power, polarity inversion, and a high-pass filter to remove unwanted low frequencies. Whether used in a home studio or a professional environment, the WA73-EQ delivers reliable, studio-quality results.
