Iconic 73-Style Sound in a Modern Package

Heritage Audio has faithfully recreated the classic sonic behavior of the original design while incorporating modern manufacturing techniques for a more affordable, accessible version.

Carnhill Transformers for Rich, Vintage Tone
At the core of the HA73EQX2 ELITE are industry-standard Carnhill transformers, handwound in St. Ives, England. These custom transformers are integral to the preamp's warm, full-bodied sound, adding richness and authority to your recordings. Whether you're recording a mic, line-level track, or DI instrument, these transformers impart that signature vintage sound. With the ability to drive the input for additional saturation, you can achieve a classic "vintage console" sound without overloading the output stage. The high-headroom, Class A circuitry ensures clarity and definition while maintaining the classic, rich tonal coloration that Carnhill transformers are known for.

Versatile 3-Band EQ for Precision Tone Shaping
The 73EQX2 ELITE features a fully discrete, 3-band equalizer that adheres to the classic 73-style EQ design. The high-frequency shelf operates at 12kHz, with a ±16dB range, adding a touch of shimmer to your tracks. The mid-frequency band is peaking with a selectable frequency range, offering six different center frequencies (360Hz, 700Hz, 1.6kHz, 3.2kHz, 4.8kHz, and 7.2kHz) to target specific tonal areas. The low-frequency shelf operates with selectable frequencies at 35Hz, 60Hz, 110Hz, and 220Hz, allowing you to tighten the bass or add warmth to lower-end instruments. The EQ section is ideal for broad tone shaping, offering plenty of flexibility to dial in the perfect sound without the need for excessive EQ adjustments.

Highpass Filter and DI Input for Added Flexibility
In addition to the EQ, the HA73EQX2 ELITE also features a frequency-selectable highpass filter. With four selectable frequencies (50Hz, 80Hz, 160Hz, and 300Hz), this filter allows you to clean up your signals by cutting unwanted low-end rumble, making it an invaluable tool for tight and focused mixes. The ultra-high-impedance JFET-based DI input is perfect for recording DI bass or other instruments with clarity and richness. By placing the DI circuit ahead of the mic input transformer, you can add some "hair" to your instrument signals, making them sound more vibrant and full, just like classic recordings from the ‘70s.

Built for Professional Studios and Reliable Performance
The HA73EQX2 ELITE is constructed with professional-grade components and built to last, offering the durability and reliability that’s expected from any high-quality studio gear. The 1RU chassis is military-spec and features a rugged, RAF-gray faceplate, making it a durable and sleek addition to any rack system. The module comes with an external universal power supply, making it suitable for use worldwide. Whether you're in a home studio or a commercial facility, this preamp/EQ module is built to deliver consistent, world-class performance every time you use it.
