The GATE (left side) is an enhanced redesign of the classic Serge Gates which can be used as a linear or exponential VCA or ring modulator or some interesting combinations of these. The VCFX 2023 is a newly designed Serge filter that is essentially a Bandpass, but also offers a Lowpass output. Features. Combined multimode VCA and band pass / low pass filter Left side VCA module with three CV control modes DC/Linear mode: initial level set with Gain control, Linear CV control with attenuverter, 0-5V output AC/Logarithmic mode: initial Gain control and Logarithmic CV control with attenuator, AC-coupled output Mod mode: enables ring modulation of input signal with signal at Mod input White jacks are DC coupled (suitable for audio or CV), Black jacks are AC coupled Lin, Log, and Mod inputs can be used simultaneously to affect output VCFX 2023 band pass filter with low pass output, 2-pole 12dB slope CV and manual control over filter resonance and frequency with attenuverters Filter input Gain control Video: https://youtu.be/7zQrAru9w9MProduct Specs Item Number: 36986 Make: Serge Modular Model: VCFX Condition: Brand New Finish: Silver Categories: keyboards-and-synths ⇒ eurorack Function: CV Modulation Filter Low Pass Gate Ring Modulator VCA Made In: Germany MPN: SM-VCFX Modular Grid: Eurorack ⓘ + Dimensions*: 18 HP 25 mm deep Power*: 24 mA +12V 24 mA -12V ? mA 5V * User contributed details
