Analogue Systems RS-400 Phaser


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


Usage with Eurorack:
Analogue Systems' modules are designed solely for use in cases and cabinets made by Analogue Systems. Through the use of adaptors or adaptor cables, however, it is possible to connect them to Eurorack cases.
Should you chose to use an Analogue Systems module in an Eurorack case, please note that the warranties are thus void and the use occurs at your own risk! If the module is plugged in incorrectly and therefore damaged the customer has to bear any costs for repair and shipping!

Because of the different position of the mounting holes there will be a gap of 0.5HP (= 2.5 mm) when mounting an Analogue Systems module next to a Eurorack module. Take this into consideration when planning your system. Gaps can be covered with 1.5HP wide blank panels by Doepfer.


Audio: signal in and out
CV: two inputs for controlling frequency, one with and one without attenuator. LFO output.
