The best of both worlds, the Heritage Audio's HA-81A is a new mix of 2 classic consoles.
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 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. 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.
