DOEPFER A-121-3 is functionally nearly identical to module A-121-2. Only the distances between the controls and sockets are smaller and rubberized, small rotary knobs are used. Therefore the front panel width is only 4HP compared to 8HP of the A-121-2. In the first place it is planned for applications where only limited space is available. The only functional difference compared to the A-121-2 is the missing attenuator for the resonance CV input CQ.  

Key Features:

• Compact multimode filter with robust performance
• Simultaneous LP, HP, BP, and Notch filter outputs
• Smooth 12dB per octave filter slope
• 2 CV inputs for controlling filter cutoff
• 1 CV input for controlling resonance
• 4HP Eurorack module
