Heritage Audio HA81A ELITE
L’HA-81A Elite è un channel strip che combina un preamplificatore microfonico in classe A 73 completamente discreto con un equalizzatore in stile console estremamente versatile e musicale, probabilmente il trucco per ottenere un suono classico istantaneo per tutti i tecnici del suono.
HA81A ELITE
ALL CLASS A CONSOLE MIC/AMP EQUALIZER
The best of both worlds.
Introducing Heritage Audio’s HA-81A: a new mix of 2 classic console´s circuits.
The HA-81A Elite is a channel strip that combines an all discrete, Class-A 73-style mic preamp with an extremely versatile and musical console style equalizer — arguably the trick for obtaining instant classic sound 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/St. Ives input and output transformers, exactly the same one found in the other Elite Series modules.
The preamp features gain, output trim, -20db pad, polarity reverse, and +48v phantom power.
The best console´s style 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 40 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
