The FM input is typically connected to the output of the associated envelope generator (e.g. A-141-4). The envelope amount for all four filters is controlled by the FM knob and the CVFM input by means of four built-in VCAs, which are controlled by the FM control and CVFM input. This allows also voltage control of the envelope amounts. \u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\u003eIn addition common frequency modulation for all filters is possible (e.g. by an LFO). For this the CVF input with attenuator can be used. \u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan\u003eThe range of the audio input level control (L) allows also clipping\/distortion with typical A-100 audio levels (e.g. from A-111-4) at the filter inputs.
