Radikal technologies

RT-451 is a double analog filter in Eurorack format, characterized by two independent analogue stages based on the circuit of the famous Spectralis by Radikal Technologies, can be used independently (therefore also to handle signals stereo) or combining them in series or parallel. Each of the two RT-451 stages includes various types of filters: highpass, bandpass, lowpass, which can be activated at the same time to create articulated combinations of filtering. RT-451 is extremely flexible: the controls on the resonance they allow you to recreate warm vintage sounds or modern sharp sounds; the Coupler knob allows to simultaneously control the frequency on both filters, whether used in series or parallel, with one single action. RT-451 is perfect for insertion inside a synth system in Eurorack format.
