Algorithmix LPEQ Classic Blue

12-in-1 - The most complete collection of classic equalizers ever in one DirectX / VST plug-in: ten serial plus two parallel
MFR# LPEQ Classic Blue

Product Description

Precise emulation of legendary analog equalizers, extended by progressive, new models: standard / vintage / modern / experimental.  A sonic paradise for every recording and mixing engineer.

A few years ago we did not even think about spending our time to develop perhaps the 157th parametric equalizer on the market.  Why one more?  Is it possible to be noticed among all the other already established products?

It was you, our customers using our LinearPhase PEQ Red and Orange who asked Algorithmix to develop a classical recording/mixing equalizer but with its unparalleled purity and transparency.  The biggest problem we had in the beginning was the equalizer style, so we closely analyzed many of them.  To satisfy our customers as much as possible, we decided to implement not only one, but an entire collection of traditional (minimal-phase) equalizers.  Most of them emulate analog archetypes; some are based on new ideas.

We hope you enjoy the dozen shades of Blue and find that favorite sound you previously could get only from very expensive outboard gear.

Shelf and Cut Filter Library

In Classic PEQ Blue, not only are various bell filters used but also different kinds of shelving filters.  Nine of the serial equalizers use a new shelving filter generation characterized by cut-off frequency defined in the middle of the transition part.  We found these filter definitions more intuitive than the classical ‘– 3 dB below maximum’.  The old definition is only used in the Classic Asymmetrical type to conform to its original predecessor.  All 2nd order shelving filters have a Q adjustment to emulate vintage characteristics with their specific bumps at higher slopes. Also, the parallel equalizers are equipped with respective shelving filters shapes being typical for the old parallel PEQs and interacting with other bands as did their analog predecessors.

Every complex PEQ is equipped with cut filters. In Classic PEQ Blue, each of the 12 equalizers can assign 1st and 2nd order cut filters.  The 2nd order filters have a Q adjustment to create so-called resonant filters characteristics and very steep brickwall filters after cascading more of them (Butterworth, Bessel, Elliptic).

The best of the analog and digital world

Classic PEQ Blue is a creative equalizing tool combining the best of both the analog and digital worlds.  We modeled the most legendary analog equalizers including two parallel ones and added a few experimental characteristics only possible in digital domain.  To avoid bell filter asymmetry at high frequencies, typical for many digital equalizers, we have applied reference-quality upsampling techniques, automatically switchable if the sampling frequency of the input signal is 44.1 or 48 kHz.  By using proprietary filter algorithms, we have achieved a huge dynamic range, as well as extremely low noise and distortion level and thus unparalleled sound purity--impossible with any analog circuitry.  The whole equalizer collection works with sample rates up to 384 kHz and therefore is perfectly suitable for DSD post-processing.  Several instances can be opened simultaneously.  Complete setups can be easily exchanged between them.  The true frequency response display is zoomable and in the DirectX version the whole PlugIn can be enlarged to the full screen.

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!

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.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
