Shaped Dual EnvVCA features: Versatile linear, exponential, and logarithmic envelope generator/LFO Low-noise, low-distortion, DC-coupled linear VCAs 100% analog Shape Slider, CV Jack and Attenuverters for fading between Exponential, Linear and Logarithmic envelope shapes without changing the envelope timing Sliders and Range switches control Rise and Fall times from ~2ms to > 2 min. Time CV jack extends time range: ~400µs (2.5kHz) to ~1 hour Independent attenuverters for Rise and Fall time Blue/Red LEDs indicate strength and polarity Cycle buttons for looping envelopes (LFO) Trigger input jack and switch for toggling between AR, ASR, and Cycle modes of triggering EOR/F (End of Rise/Fall) gate outputs can be used to chain and sequence events Env Level and Offset knobs scale and shift Env Out without changing VCA volume Audio In and Out jacks for passing audio or CV through the VCA VCA CV inputs to use VCAs independently from the envelopes: VCA gain internally connected to envelope output when VCA CV jack is left unpatched Follow input jacks allow for slew limiting, ADSRs, and exotic filtering effects Re-trig jumpers allow for re-triggering during rise phase Shaped Dual EnvVCA 20HP Eurorack format module 0.95” (24mm) maximum depth (includes power cable) 10-pin Eurorack power header Power consumption +12V: 255mA -12V: 230mA Audio/VCA 100k input impedance, 1k output impedance, DC-coupled VCA gain range: -90dB to +2.0dB, linear response to CV from 0V to 5V VCA unity gain: 4.4V CV DC to 20kHz, +/-0.1dB Envelope Times Minimum rise or fall time: ~200us per segment (2.5kHz max frequency) Maximum rise time: >20 minutes (typically > 40 minutes) Maximum fall time: >12 minutes (typically > 20 minutes) Jacks: Env jack: Min = -10.2V, Max = +10.1V , maximum amplitude 9.3Vpp Trigger jack: rising edge threshold = 1.25V Follow jack: active range = 0V to +5V EO* jacks: EOR (channel A): 4.50V high gate output EOF (channel B): 4.95V high gate output Minimum stable pulse width: 1ms. Shorter than this may produce extra 50µs pulses Audio In/Out jacks: -10V to +10V maximum range without clipping
