Analogue Systems RS-400 Phaser


Classic phase shifter with four stages

Available on back-order

SKU: ANALRS400 Category: Brand:


Classic phase shifter with voltage control and an integrated LFO which you can tap. The phaser has four stages resulting in two notches in the frequency range only but a distinct sound.

The frequency control sets the position of the two notches; in minimal setting they are at 20Hz and 120Hz, in maximal setting at 7.5kHz and 45kHz. the frequency can be modulated by two CV inputs and an integrated LFO. Emphasis parameter is a positive feedback, epmhasizing the peeks between the notches and it reaches short of self-oscillation.

The LFO can be used for modulating other parameters as it can be tapped at a socket. A triangle wave is produced and the LFO´s frequency range is roughly between 0.2Hz and 10Hz.
