4ms VCA Matrix
4x4 voltage-controlled matrix mixer with per-crosspoint CV and mute
26 HP Eurorack module
The 4ms VCA Matrix is a 4-input, 4-output voltage-controlled matrix mixer. Each of the 16 crosspoints has its own VCA with a manual level knob, a CV input jack, and a mute button. Any combination of the four inputs (A, B, C, D) can be routed to any combination of the four outputs (1, 2, 3, 4) with independent level control. This makes it ideal for complex signal routing, quadraphonic panning, feedback patching, and dynamic mixing where every path can be voltage-controlled independently.
Features
- 16 independent VCAs in a 4x4 matrix configuration
- Per-crosspoint CV inputs for full voltage control of every routing path
- Individual mute buttons with LED indicators for each of the 16 crosspoints
- Manual level knobs for each crosspoint with unity gain at full CW
- Handles audio and CV signals equally well
- DC-coupled for processing control voltages and audio
