The IGS Audio Rubber Bands consists of two blocks: The first block is a classic passive filter known from the EQP-2 device. The second block is a specially designed two-stage tube amplifier called Organic Amp. Due to its construction, passive equalizers' culture is characterized by amazing sound.

The new design includes a bypass relay, which allows you to instantly compare the results of your work. The equalizer has been divided into 4 sections: 2 for bass and 2 for treble. Bands are selected with stepped switches. Boosting and cutting are controlled continuously. Manipulators featured are Bass Boost, Bass Cut, High Boost (with the choice of Q) and High Cut. Interactions of filters that allow simultaneous boosting and cutting of certain frequencies can produce amazing sound effects. Many performers believe that the passive equalizer is a cure for all digital evils. A distinctive characteristic of this IGS Audio Equalizer is its stereophonic structure, where the manual selecting of components with an accuracy of 0.2% allows for perfectly synchronous manipulation of both channels. The inputs and outputs are transformer balanced. Works with+4 dBu balanced signals.
