Precise & All stepped controll
IGS IQ Equalizer is a modern application of the noble sound of analog equalizers. This very precise, parametric equalizer works great on every stage of production. It can add marvelous color to the signal, while maintaining the whole character of the original sound. This is a unique phenomenon possible only with analog processing. As opposed to digital eq it maintains neutrality and clarity on every setting. The simultaneous boosting and cutting of similar frequencies are the core secret of this device.
This is the typical effect of analog filters in the audio path. Most of the sound correction is in micro-manipulation. The frequency range is divided into 4 bands: Sub, Bass, Mid, High. In every band the frequency and boost/cut level can be set.
Great, here s your stereo unit
Many sound engineers believe that the passive equalizer is a cure for all digital evils. A distinctive characteristic of the IGS Audio Rubber Bands Equalizer is its stereophonic structure, where the manual selecting of components with an accuracy of 1% allows for perfectly synchronous manipulation of both channels. The inputs and outputs are transformer balanced.
The Rubber Bands EQ consists of two blocks: The first block is a classic passive filter well known from the EQP-1 Pultec equalizer. The second block is a specially designed two-stage tube amplifier called Organic Amp.
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. Frequencies are being 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.
RB 500 ME
RB500ME is a stereo passive equalizer packed into a double 500-series module. This beast is equipped with transformer balanced inputs (Carnhill) and outputs (Edcor) as well as a class-A driver circuit. Of course the entire filtering section is passive and it mirrors analogue equalizers from the 60s. There is separate frequency selector for low cut and boost sections. Top quality potentiometers and ELMA switches were used to achieve outstanding performance.
Pulteq Style EQ
Rubber Bands 500 is a passive equalizer absurdly reduced in size. This tiny module is equipped with transformer balancing on input and output (Carnhill) as well as a discrete driver circuit. Of course the entire filtering section is passive and mirrors analogue equalizers from the 60s. There is separate frequency selector for low boost/cut sections. And you get the true bypass switch as a bonus!
