Heritage Audio HA-81A Channel Strip
The Heritage Audio HA-81A Channel Strip 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 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 responsecurves 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 our 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.
