The SF1 is a dual voltage controlled filter (VCF) module designed to be used either as a pair of identical, but separate VCFs, or as a stereo filter. 9 possible output responses are available from the 2 concurrent outputs for each filter/channel. "Link" mode is ideally suited for stereo applications and allows both filter's cutoff, resonance, and cutoff/resonance CV to be simultaneously using the left-hand controls/inputs. The outputs are routed to a CV-controlled panner/crossfader, allowing modulation of the spacial location of each filter. Features Dual/Stereo VCA module Offers both vintage transistor and modern chip-based VCAs per channel Input with up to +6dB input gain Bias controls CV attenuators with up to 2x gain Optional stereo link feature Overdrive on/off switch Optional zero-crossing detection circuit to reduce clicks from snappy envelopes Specs 18HP module size, 25mm Deep Power: 120mA +12V / 120mA -12V Video: https://youtu.be/H6GdoDR4gZMProduct Specs Item Number: 36893 Make: Weston Precision Audio Model: SV1 Condition: Brand New Finish: Black Categories: keyboards-and-synths ⇒ eurorack Function: Distortion Dual/Stereo Mixer VCA Made In: United States MPN: WPA-10194 Modular Grid: Eurorack ⓘ + Dimensions: 12 HP 33 mm deep Power: 70 mA +12V 70 mA -12V 0 mA 5V
