Fredenstein ARTISTIC EQ Overview

Outfitted with switchable harmonic coloration for sonically enhancing tracks, the Fredenstein Artistic EQ is a 500 Series 3-band equalizer offering high-quality tone shaping in a highly accessible price class for producers, musicians, and engineers. The discrete signal path features an American-made output transformer as well as Fredenstein's specially designed OPA2 opamp, allowing it to impart a smooth sonic signature along with high-performance noise and distortion specs. A simple press of the Color button adds harmonics based on tube-type circuits, a great way to liven the sound of your source in a hurry.

Each of the three EQ bands provides up to 14 dB of boost or cut and variable frequency control—30 to 300 Hz for the low band, 300 Hz to 3 kHz for the mid band, and 2 to 20 kHz for the high band. Additionally, the low and high bands have independent switches to select bell or shelf for the filter characteristic. The face of the Artistic EQ has power and clip indicators at the top and a bypass switch at the bottom.

Discrete Amplifier Circuit
The centerpiece of the Artistic EQ is the OPA2 discrete audio operational amplifier. As in all Fredenstein products, the OPA2 is not a copy of an older design, but is a completely new design manufactured in SMT technology with matched and integrated dual input transistors to guarantee vastly improved specifications compared to older designs. The OPA2, in the tradition of similar modules, is socketed and can be exchanged without tools.
Output Transformer
The sound is further defined by the American-made, steel-core output transformer, which is known for its smooth, vintage sound without being dark or mushy.
Harmonic Coloration
The Artistic EQ features a flip switch for its Color mode, a circuit that introduces harmonic coloration based on tube amp characteristics.
3-Band EQ
The high band covers 2 to 20 kHz, the mid band offers frequencies between 300 Hz and 3 kHz, and the low band is adjustable from 30 to 300 Hz. The high and low bands can be set to bell or shelf filters, and each band provides up to 14 dB of boost or cut.
Extra Features
The Artistic EQ also features a power indicator, a clip LED that lights when the signal level is over +24 dBm, and a bypass switch.
