It’s the perfect blend of vintage character and contemporary design for today’s studios.

Classic British Console Sound with Modern Efficiency
At the heart of the HA73 Elite is a fully discrete, 3-stage Class A design that provides up to 80dB of gain, making it perfect for any microphone type, from condenser to ribbon to dynamic mics. Inspired by the iconic vintage consoles that shaped the sound of countless classic recordings, this preamp injects your recordings with vibrant clarity and punch. The gain structure allows for a wide range of tonal possibilities, from clean and transparent to rich, saturated tones that emulate the vibe of a classic British console. The HA73 Elite ensures you can drive your sound with the depth and warmth that made vintage preamps so revered.

Carnhill Transformers for Warmth and Authority
The HA73 Elite is equipped with genuine Carnhill input and output transformers, hand-wound in St. Ives, England. These transformers add warmth, girth, and authority to any sound source, whether it’s vocals, instruments, or line-level tracks. The transformers are the key to getting that unmistakable vintage character that so many engineers and producers crave. Whether you're recording through a mic or processing a line input, the Carnhill transformers give your sound the richness and fullness that’s hard to achieve with cheaper, mass-produced components.

Versatile Controls for Tailored Sound
Heritage Audio has designed the HA73 Elite with a focus on flexibility and ease of use. The preamp features separate input and output gain controls, allowing you to drive the input hard to achieve transformer saturation without overloading the output stage. This is especially useful when you want to add color and character to your sound without introducing distortion or clipping. Additionally, the mic input is equipped with a 20dB pad to prevent overloading the transformer, giving you even more control over your signal. The LOZ switch allows you to adjust the input impedance of the mic transformer from 1200 ohms to 300 ohms, giving you further tonal flexibility for different mics and sources.

Powerful DI Input and Highpass Filter for Cleaner Recordings
The HA73 Elite is equipped with an ultra-high-impedance JFET-based DI input, allowing you to easily record instruments like bass, guitar, and keyboards directly into the preamp with minimal signal loss or coloration. This feature makes it a perfect choice for adding warmth and presence to your direct inputs, especially when recording bass. The 80Hz highpass filter helps eliminate unwanted low-end rumble, providing cleaner recordings and preventing your tracks from becoming too muddy. Whether you're tracking or mixing, the DI and highpass filter work together to give you greater control over your sound.

Rugged Build and Universal Power Supply for Reliable Performance
Designed to withstand the demands of professional studios, the HA73 Elite comes in a rugged 19" 1RU format chassis, making it easy to integrate into any standard rack setup. The external universal power supply ensures that the preamp can be used worldwide, offering flexibility for any studio setup. Heritage Audio’s commitment to quality craftsmanship means that the HA73 Elite is built to last, providing reliable performance and world-class sound for years to come.
