Description

The 4ms VCAM: VCA Matrix is a powerhouse module for any Eurorack enthusiast looking to expand their creative potential. This playable 4x4 matrix of 16 VCAs offers unparalleled flexibility, allowing you to route four CV/audio inputs to four outputs in any configuration you desire. Each VCA features its own gain control and illuminated mute button, empowering you to sculpt complex soundscapes with ease. The module's soft limit circuitry ensures you can push your sonic boundaries without fear of clipping, while the exponential and pseudo-log response curves provide nuanced control over your dynamics.

Whether you're using it as a mixer, splitter, or dynamic signal router, the VCA Matrix's intuitive design encourages hands-on experimentation. The module's expandability means you can link multiple units to create even larger matrices, making it a versatile tool for any modular setup. With its high-quality SSM chips, the VCA Matrix not only delivers pristine audio fidelity but also offers robust control and precision for all your synthesizing needs.

Key Features:

  • 16 VCAs with independent gain control and illuminated mute buttons
  • 4 CV/audio inputs and 4 buffered, dc-coupled outputs
  • Frequency range: 0Hz - 20kHz
  • Soft limit circuitry to prevent clipping
  • Exponential VCA response in low control voltage range, pseudo-log response at higher ranges
  • Expandable matrix configuration for larger setups
  • Attenuation/gain range from -100dB to +20dB
  • Playable surface with latching Mute LED buttons
  • Suitable as a mixer, splitter, dynamic signal router, and more
