What is HA-81A EQ?
HA-81A EQ is the plug-in version of Heritage Audio’s console-style channel strip “HA-81A EQ”. It combines the company’s 73-style preamp with a four-band EQ that uses inductors (coils) (per the manufacturer).
The license is iLok-based, and the manufacturer’s page offers a 14-day demo (per the manufacturer).
How it compares with similar products is summarized in EQ plug-ins compared.
Features
A classic console EQ: four inductor-based bands
HA-81A EQ is based on Heritage Audio’s award-winning hardware console EQ. The official page explains that its four inductor-based bands have become one of the standards of vintage EQ.
Tidy vocals, guitars and midrange instruments naturally
The official page explains that when you shape vocals, guitars and midrange instruments, the adjustments feel natural and expressive.
Also for drums, bass, piano and strings
The official page explains that the bass sounds rich and tight, the highs have fine sparkle, and the midrange pushes the sound forward (per the manufacturer).
A channel with the 73-style preamp
You can use it as a console channel that combines the company’s 73-style preamp with the inductor EQ.
For owners of the hardware, and the demo
The official page says that people who own the HA-81A EQ Elite Series or i73 PRO hardware can use the plug-in for free. A 14-day demo version is also available.
