The 411 is a quadruple linear VCA, mixer, and multiple for audio and CV. It consists of four linear VCAs with semi-normalled inputs and CV inputs, −6 dB attenuation switches, a mixed output, and an unpatched output. The 411’s architecture allows to use it in many ways, for example: processing four signals independently; modulating one signal with four CVS and sending it to four different destinations; mixing up to four signals and modulating them with the same CV; mixing two audio signals and modulating them with a modulated CV… Size 6 HP Depth 38 mm Current draw 35 mA @ +12 V 25 mA @ -12 V Recommended warmup time 30 min Audio Input impedance > 45 KΩ CV Input Impedance > 40 KΩ Output impedance ~ 100 Ω Global CV offset per section -20 to 20 mV Frequency response DC to 30 KHz Harmonic distortion (THD+N) < 0.1%
