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 a slope of -24dB as used after 1974.
The cutoff frequency and also the resonance are voltage controllable. Signal inputs and outputs have level controls.
The Dual Bus version of the RS-500e features two power connectors, meaning it can be directly connected to either an Analog Systems or a Doepfer modular system. – Adapters are no longer necessary.
Because of the different position of the mounting holes there will be a gap of 0.5HP (= 2.5 mm) when mounting an Analogue Systems module next to a Eurorack module. Take this into consideration when planning your system. Gaps can be covered with 1.5HP wide blank panels by Doepfer.
