Analogue Systems

Notes: Genuine EMS synthi filter, with redesigned faceplate!

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.

Notes: The RS-650 Echo / Reverb is a combination of the RS-310 and RS-440 which are based on the same circuit.

It offers both delay (echo) and reverb settings in one module. It is based on a bucket brigade device (BBD) with six parallel delay taps. Those six delay times have no relationship to each other and their outputs have different levels. You have to consider the reverb effect as a mixture of six different short delays what results in a dense sound. The clock frequency which scans the bucket brigade is audible and you'll have to use a low pass filter in order to eliminate or minimize it. In Reverb mode the delay time can be set between 2.5ms and 150ms and in Echo mode it spans from 75ms to 200ms.

All modules by Analogue Systems come ready to use with five years warranty mounted in the by the customer preferred rack or cabinet.
