The A-123 is a voltage controlled (VCF) with a cut-off slope of -24 dB/octave. The cut-off frequency determines the point at which filtering takes effect and can be controlled manually, or by voltage control (filter modulation, for instance by an LFO). Two CV inputs are available. Resonance (Emphasis or Q ) can be adjusted manually, or by voltage control (VCQ), right up to self-oscillation, in which case it will behave like a sine wave oscillator.[1]
The A-123 has been discontinued as the CEM3320 IC used in this module is no longer available.[1]
