Heritage Audio HA73EQ Elite Microphone Preamp/EQ

Fully discrete, 3-stage Class A mic preamp/EQ with correct “Vinkor” type pot core inductors - zero compromise, high-quality design
MFR# HA73EQ

Product Description

The Heritage Audio HA73EQ Elite is made to the same specifications as the acclaimed 73JR and DMA73 Heritage Audio models. Leveraging time-consuming hand-soldered series, Heritage Audio is able to offer a zero compromise, high-quality, yet very affordable alternative to the growing entry-level brands.

Manufactured in the same Spanish facilities as the rest of the Heritage Audio line of products, the rack-mountable HA73EQ Elite presents the classic sounding recording preamp that, for generations, has been regarded for its rich, musical qualities and its ability to dramatically improve the sound of almost any source. Further, it includes the same exact great sounding JFET DI circuit found in the 73JR as well as a fully discrete Class A high-pass filter.

No 73-style equalizer will present the correct equalization curves without high-quality capacitors and, most importantly, correct “Vinkor” type pot core inductors. More than often this type of product employs generic ferrite core ones or, worse, the mid band dual inductor replaced with a single one. This is never the case with Heritage Audio products! The impact replacing these has on the EQ curves is dramatic, leading to incorrect curve shapes and high-frequency phase distortion which in no way honor the original design.

The HA73EQ Elite employs WIMA 5% capacitors in the EQ section as well as 3 correct vintage type “Vinkor“ pot core inductors so the EQ curves are virtually undistinguishable from the handmade equalizers in the Heritage Audio line. Customers can expect the same sonic quality and feel they have come to appreciate from Heritage Audio.

The HA73EQ’s preamp section features gain, output trim, -20 db pad, polarity reverse, a high-pass filter, and +48 V phantom power. The HA73EQ’s EQ section features a high shelving EQ, midrange EQ, low shelving EQ, a variable high pass filter, and EQ Bypass, The HA73EQ comes housed in a rugged 1RU British steel and aluminum chassis and utilizes an external power supply for low noise operation.

The key components to obtain that true vintage sound are maintained, like the industry standard Carnhill transformers, hand-wound in St. Ives, England.

The unit sounds great. Very very close to a real 1073. The unit sounds better with eq engaged even if your not using the eq. Just having it engaged does something that I like. Overall a great unit!

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.
Michael D.
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.
