Get The Sound of The Mixing Desk from 80’s

Everybody loves the sound of Valve Recording Equipment from 50’s and 60’s or the Vintage Transistor Mic Preamps from 70’s.

But what with the Signature Sound of 80’s? This decade has also place in the history of Music Production…

That was the time when the integrated circuits became quite popular. Silicon Opamps encapsulated in the metal cans replaced the discrete circuitry creating new type of sound featured in many Greatest Hits from 80’s!

The EQ5169 is the first EQ which uses Vintage NOS Integrated Circuits. The same integrated circuits which were used in late 70’s and early 80’s in the Studio Recording Equipment. Those Components created the characteristic sound of old consoles from 80’s due to the limited bandwidth and specific distortion performance. Those first Opamps were the essential ingredient of the 80’s Sound!

With The EQ5169 you can get the original Sound of 80’s in your Recording Studio!

User Review

A close up of my first EQ builds, inspired by the extremely musical Studer 169 console EQs. Just like the original Swiss made consoles built in the 80s, these are Baxandall EQs, which is a type of EQ great for sweetening and general tone shaping. Also like the originals, these use 1980s ICs (integrated circuits) that add an almost SSL like edge and punch to the sound... but unlike the consoles, these have custom transformer coupled inputs and outputs. The transformers in addition to the bax curves make it near impossible for these EQs to sound stringent like certain SSL EQs can when pushed too hard, and it sacrifices some of the surgical possibilities for a much smoother, richer, and fuller tonality. Absolutely beautiful sounding on lead vocals, guitars (my 2nd favorite application), drums (my favorite application), and keyboards/synths, these little guys can cover a lot of ground even with seemingly limited high and low shelf frequency options. The sweepable midrange adds tons of versatility though, and just like some of the best transformer coupled units, simply running signal through these equalizers, even with the EQ circuitry bypassed, adds some warmths and life to the track. If you go to barthrk.co.uk you can preorder either a DIY kit or preassembled unit from the next batch. Near unbelievable bang for your buck. - Michael Frasinelli ----------------------------------------------------- #nashvillemusic #diy #recordingstudio #musicstudio #equalizer #analog #gearhead #recording #mixing #mastering #master #studiolife #producerlife #audioengineer #audioengineering #musicproducer #eq #proaudio #drumkit #acoustic #acousticguitar #guitarplayer #indie #indierock #indiemusic #singersongwriter #popmusic #classicrock #rnbmusic #vintage

Coupled with Custom HRK Transformers

Input and Output of the EQ5169 are coupled with specially designed custom HRK Transformers.

Because of limited space in the 500 Unit, HRK Custom Transformers became smaller, still maintaining no-compromise performance.

All HRK transformers provides the sweet-spot sonic characteristic with pristine details reproduction.

The goal of the design process was to create the transformer which will deliver balance between the transparency and colouration typical for transformer stages.

The success was achieved by outside-the-box thinking during the design process and use of selected custom materials.

Musical EQ Inspired by Swiss Design

The EQ5169 3 band EQ with the quasi-parametric Mids Control was inspired by very popular classic Swiss console design.

Although the EQ5169 may look simple but it gives almost infinite creative possibilities thanks to the musical EQ curves and the intuitive controls.

The LOW and HIGH Bands have 3 frequency settings selectable by 3 position toggle switches.

The sweepable MID section covers the frequencies between 200Hz and 8kHz.

All 3 Bands have boost/cut range of +/- 15dB.

The EQ5169 is very easy to use even for beginners and it is valuable addition to your studio toolbox!
