Genuine EMS synthi filter. This legendary filter can be switched between pre1974 and post 1974 filter type and response. For the first time response can be voltage controlled which was designed on the circuit board but not available on the matrix. This module is made under license from EMS.
The only officially licensed remake of the EMS diode lowpass filter used in the VCS3 and AKS synths. It´s a faithful recreation of the original circuit, featuring some modifications that are also done on vintage EMS equipment, like a switchable faster CV response option for very quick modulations. Another switch determines if the filter has 18dB/oct slope as used by EMS pre-1974 or 24dB. The cutoff frequency and also the resonance are voltage controllable. Signal inputs and outputs have level controls.
