Description

The AR-314 is a basic 12db-per octave low pass filter with voltage controllable cut-of frequency and variable resonance (Q). This filter modifies the harmonic content, or spectrum, of an incoming signal by damping all frequency components of the waveform above a certain cut-off point. The resonance control boosts the amplitude of the frequency, or harmonic of the incoming wave, closest to the cut-off frequency, by a variable amount according to the manual setting. The control input varies the cut-off frequency at 1 octave per volt of input signal: positive voltage will raise the cut-off and negative voltage will lower it.
