The PEQ-1A is a 2U-high mono tube unit based on the Pultec EQP-1A. This is however not a faithful copy of the original, but rather an improved version which, besides increased abilities, preserves the sonic quality of incoming signal.
The lineage of the 5500 circuit can be traced back to the original 550 equalizer designed by Saul Walker, the founder of Automated Processes Inc. and like all API products, the 5500 contains no integrated circuits in its signal path.
The AD2077 mastering equalizer is an ultraistic design optimizing absolute signal integrity. Design features include 100% discrete pure class A signal amplifiers, state-of-the-art passive and active filter topologies and a DC coupled minimalist signal path.
We wanted to build an audio equalizer with the sound of real passive resonant circuits (chokes and capacitors) but without sacrificing the adjustability and flexibility demanded by recording and mastering engineers.

Brought to you from the man who invented the very concept of Parametric Equalization, the 8200 has been an industry standard for over twenty years, and can be found on virtually every major recording studio’s stereo bus.
Craig 'HUTCH' Hutchison designed these monsters... The MASSIVE PASSIVE is a two channel, four band equalizer, with additional high pass and low pass filters. "Passive" refers to the tone shaping part of this clever new EQ design not using any active...
The new RETRO 2A3 is designed as an ultra High-Fidelity Program Equalizer whose sonic benefits go beyond the equalization process. Accurate to the industry-standard Pultec EQ performance, the RETRO 2A3...
The EQF-100 uses both solid state and tube technologies to produce the warm sounds associated with tubes, while providing the reliability of solid state devices.
The Summit Audio EQP-200B is a full range two channel passive equalizer that utilizes vacuum tube technology to overcome any gain loss. Based on the original Pultec program equalizer design, the EQP-200B uses a tried-and-true design with some added Summit magic....
For the first time, Weiss Engineering brings an exciting new feature to its EQ palette: dynamic control in the frequency domain. You adjust the EQ to a nominal setting. The input signal is then analyzed to determine exactly how much equalization need actually...
The EQ1 is available in four different configurations. All of them work at 24/96. The basic model is the EQ1-MK2, the linear phase model is the EQ1-LP, the dynamic model the EQ1-DYN. The EQ1-DYN-LP incorporates both LP and DYN versions in one unit. The mode of...
