History:

PE1A  The First Tube-Tech Unit in Production.

"Tube-Tech program EQ is exactely the same as Pultec program EQ!"

This was our statement when promoting the very first Tube-Tech equalizer back in 1985.

The Tube-Tech PE1C program equalizer was originally made as a European exact equivalent of

the US Pultec program eq, that became very popular in the US during the eighties in recording studios in New York and LA. The smooth sound of the Pultecs made these eq''s very different and attractive. The challenge of this illusive sound motivated Tube Tech founder and designer John Petersen to design and manufacture something that sounded just as good.

The magic test was a Pultec EQ1P on the left and Tube Tech PE1A on the right and check the stereo image: It had to remain perfect on all settings!       

The PE1A was the first product carrying the name TUBE-TECH 25 years ago.

A vintage product still in production!

Today the Tube-Tech PE1C is still in production, with little changes in sound from its original design.

Sound:

The PE1C is the only program eq that does exactly the same thing as the original Pultecs did when new. We mean "did" because today the Pultecs often are more "grainy" sounding today due to age and very old components.

The high end boost of the PE1C is a one off a kind and nothing comes close.

Try it on dark sources like a Coles ribbon mike and hear how nice the top end gets opened up without harshness. 

The sound obtained with the PE1C is impossible to get with other standard active eq''s due to the filter types, the tube gain stages and transformers.

There''s a lot of creative possibilities and magic hidden in this seemingly simple eq. The low end section is a combination of two separate passive eq filters with a little different cut/boost frequencies,even  though the front panel shows the same frequencies for these functions.

In reality the boost frequencies are a little lower than the attenuation frequencies, something the original Pultecs did and the Tube Tech carries over..

"THE LOW END TRICK"   This feature results in special eq curves when the two sections are combined

"THE TOP END" A smooth top end on sources is the key to improved definition without getting "bright". This is very hard to accomplish with modern active eq's.

The PE1C features extended mid/hi boost ranging from 1 Khz to 16 Khz.

Overall this smooth passive eq is equally suited to many jobs in the studio, from opening up vocals and guitars to tuning bass drums in the most exciting way.

Important! 

This is NOT a dull and muddy sounding old school equalizer, and so wasn''t the Pultec.

Classic well built Tube gear always featured extended frequency response and open sound.

This is the backbone of the TUBE-TECH sound.

The sound samples on this player also covers the sound of the modular PE1C: EM1A, since the circuits and sound in the two units are exactely the the same.

""There are very few pieces of outboard gear that I depend on, and very few audio company's that I trust. However, anyone that's worked with me at Daptone Studios can testify that the dominant color of my humble outboard rack is Tube-Tech blue. I have grown to depend heavily on their PE1C and ME1B equalizers for their unique musicality. I am able to distinctly reshape drums, horns, vocals, orchestral tracks, or even entire mixes without making them sound effected or cappy.
I can honestly say that I depend more heavily on Tube-Tech than on any other outboard gear. I endorse their products with confidence."

The TUBE-TECH PE 1C is a passive tube based program equalizer designed to meet the exacting standards of even the most demanding studio engineers.

The TUBE-TECH PE 1C Program Equalizer contains a low frequency boost and attenuation section (shelving), and a high frequency boost section (peaking). The high frequency section has variable bandwidth as well as attenuation (shelving). The filter section is of the passive type followed by a tube based push-pull amplifier to restore the gain.

Input and output are balanced as well as fully floating. Input and output transformers come with a static screen between the primary and secondary wirings.
