Get a classic 73-style preamp and 81-style equalizer in one box with Heritage Audio's HA-81A, an all-discrete channel strip with no-compromise build quality.

Overview

Introducing Heritage Audio's HA-81A: a mix of 2 classic consoles. The HA-81A is a channel strip that combines an all discrete, Class-A 73-style mic preamp with the infamous 81-style equalizer -- arguably the most in-demand products for all recording engineers.

The mic preamp that meets the demands

The HA-81A's preamp section is an 80 dB, all discrete Class-A design with Carnhill and St. Ives input and output transformers. To put it simply, it's an exceptional Heritage Audio take on the infamous 73-style preamplifier.

The preamp features gain, output trim, -20db pad, polarity reverse, and +48v phantom power.

The best console equalizer ever made

The HA-81's equalizer section is an exceptionally musical 4 band, inductor-based equalizer with high and low pass filters. Where 3 band equalizers such as the typical 73-style exceed at musicality but may get short of features, the HA-81A EQ equally excels on both. Extreme control over Shelf or Bell response curves on the high and lows, dual Q on both mid bands, with dedicated high and low mid ones, and a range of 30 frequency selections to choose from.

Hybrid design. Heritage quality.

The Heritage HA-81A utilizes only rotary switches and precision, concentric potentiometers. And like all of the products in the Elite range, the HA-81A is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners - all at the Heritage headquarters in Spain.… read more
