Heritage Audio HA-73EQ Elite Series Microphone Preamplifier Equalizer
The Heritage Audio HA-73EQ Elite Series makes vintage audio quality accessible for modern studios. By combining efficient manufacturing with high-quality components, Heritage Audio delivers the rich, classic British sound without the high cost of vintage gear. It's an ideal choice for engineers seeking authentic analog character without relying on decades-old hardware or digital imitations.
Authentic Analog Character
The HA-73EQ's preamp breathes life into any microphone. Whether you're capturing delicate ribbon mics or driving dynamic ones, its fully discrete, Class A circuitry delivers the punch and clarity you expect from high-end gear. This preamp offers the thick, musical saturation plugins can't replicate, giving your tracks immediate weight and presence.
Class A Power: Boasts a fully discrete, 3-stage Class A mic preamp with up to 80dB of gain, ensuring you have plenty of clean, powerful headroom for any source.
Authentic Iron: Features industry-standard Carnhill transformers, hand-wound in St Ives, England, to deliver that unmistakable, weighty vintage tone associated with classic consoles.
Smart Input Options: Includes a dedicated line input on a separate XLR for adding warmth to pre-recorded tracks, plus a -20dB pad to tame hot signals without losing character.
Sculpting the Sound
This is a complete channel strip built to sculpt your sound with surgical precision and vintage warmth. The equalizer section faithfully recreates classic 73-style curves, utilizing authentic "Vinkor" pot core inductors to preserve the phase coherence and harmonic character of the original hardware. It’s designed to be effortlessly musical, making it nearly impossible to dial in a bad sound.
Versatile Mid-Range: Offers a mid-band boost/cut that is selectable between six different frequencies, allowing you to punch through a mix or scoop out mud with ease.
Smooth Shelving: Features a fixed high shelf at 12kHz for adding air and sheen, and a low shelf selectable between four frequencies to tighten up your bottom end.
Clean Up Your Signal: Equipped with an inductor-based High Pass Filter with four selectable frequencies, perfect for eliminating rumble and low-end noise before it hits your converters.
Professional Reliability and Build
From the rugged chassis to the high-quality JFET DI, every element is engineered for professional reliability. It’s a workhorse ready to sit in your rack for the long haul, providing consistent results session after session.
Direct Injection: Features an ultra-high impedance, JFET-based DI input on the front panel, perfect for capturing bass and guitars with rich, active-style clarity.
Impedance Matching: A LOZ switch changes the mic transformer input impedance from 1200 to 300 ohms, giving you tonal flexibility and better matching for vintage ribbon mics.
Global Power: Utilizes an external universal power supply, keeping noise away from your audio circuits while ensuring compatibility wherever your music takes you.
A Modern Classic for Every Studio
The Heritage Audio HA-73EQ Elite Series proves you don’t need a big budget to achieve legendary sound. Blending modern manufacturing with vintage audio character, it delivers a high-quality signal path that enhances your recordings from the very first take.
