A transistor-ladder-style filter, the A-103 is perfectly suited for crafting the signature sound of Acid House, applying the subtle crunch and harmonics that is synonymous with the genre.
Jam-packed into an 8HP module, the Doepfer A-103 includes three CV inputs, with CV1 utilising 1V/Oct standard. Driving the resonance to the maximum into self-oscillation, this control allows you to patch pitch signals in and use the A-103 as its own dedicated sine wave generator. Ideal for live performers, the Doepfer A-103 boasts a smooth frequency cut-off which subtly rounds out the low-end of your signal to maintain the punch even under extreme resonance.
From squelching bass to dynamic drum sweeps, the A-103 is the ultimate companion for the modern producer or live performer seeking to recreate the classic sound of the mid to late '80s.
