Heritage Audio has expanded its software lineup with a digital version of the HA-81A EQ, one of its most popular hardware products. The plugin replicates the original four-band equalizer design, which pairs the manufacturer's preamp technology with an inductor-based equalization circuit modeled after classic 1073-style gear.
The software provides versatile tonal shaping capabilities across multiple frequency ranges. Users can configure the low and high frequency sections to function as either shelving or peaking filters, while two midrange sections offer fixed peaking with an optional High Q mode. Additional filtering options include separate controls for removing unwanted low-end and high-end frequencies. Heritage Audio says the plugin works well across various applications such as vocal processing, instrument balancing and rhythm section refinement.
The HA-81A EQ plugin costs 99 euros and supports VST3, AU and AAX formats on Windows 10 or later and macOS 10.15.7 or newer systems. Customers who purchased the physical hardware unit or the company's i73 PRO interface can obtain the software without charge through a redemption process available on the manufacturer's website.
