Heritage Audio HA-81a Microphone Preamp/EQ

Mic pre/EQ combining an all-discrete, Class A 73-style mic preamp with the famous 81-style equalizer

MFR# HA81a

Product Description

Introducing the Heritage Audio HA-81A - a new mix of two 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, -20 dB 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 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.

FEATURES:

  • Classic European console preamp and equalizer; a hybrid design based on two of the best designs ever made
  • Full-featured 71-style mic preamp
  • Full-featured 81-style equalizer
  • Built at Heritage headquarters in Spain

Great Pre and EQ. Sounds great on many sources, specially drums and guitars! The HP and LP filters are great for adjusting mic tone during recording. Build quality is excellent. Nothing more to say.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
