INVENTORY #58509

BRAND: Blue Lantern

MODEL: Diode VCF Rev 4

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for a Blue Lantern Diode VCF Rev 4 Eurorack Synthesizer Module. The Blue Lantern Diode VCF Rev 4 is an analog Eurorack filter module based on a 10-stage diode ladder core, heavily influenced by the classic Steiner-Parker filter design. It is known for its aggressive, "drippy," and "screeching" resonance, making it a popular choice for acid-style patches and harsh, metallic textures.

SPECS:

• 10-Stage Diode Core: Provides a distinct analog character with high-gain potential.
• Simultaneous Multimode Inputs: Features dedicated, mixable inputs for Low Pass, Band Pass, and High Pass filtering, allowing you to blend different VCO signals through different filter states simultaneously.
• Ping Circuit: Includes a "Ping" input that allows a trigger signal to "pluck" the filter, ideal for creating percussive sounds without an external envelope.
• Integrated VCA: Modern versions often include an onboard VCA, making it a compact "voice" module when paired with an oscillator.
• Control Refinements: Precision trimmers for cutoff and resonance calibration, along with DC cutoff on the resonance circuit, help stabilize the module compared to older revisions. 
• Width: 10HP.
• Depth: Approximately 32mm.
• Current Draw: Typically around +16mA and -15mA.
• Inputs: (1) FM bi-polar input, (1) Direct CV input, (1) Ping input, and (3) mixable audio inputs (LP, BP, HP).
