2HP VCM
A 2HP Eurorack module that functions as a passive, three-channel voltage-controlled mixer with a single CV input for simultaneous level control.
Overview
The 2HP VCM is a Eurorack module made by 2HP. It serves as a compact, passive mixer for combining multiple signals directly within a modular setup. The module features three input channels and one summed output, with a single CV input that controls the level of all three channels at once. It requires no power, making it a space- and resource-efficient solution for blending signals like LFOs, oscillators, noise, or envelope generators without占用 additional power headroom.

Design
The VCM uses a passive circuit topology consisting of three logarithmic potentiometers wired into a passive summing network. This minimal design eliminates the need for power while allowing direct, voltage-controlled blending of signals. Due to its passive nature, the module slightly attenuates the signal and may introduce high-frequency roll-off, especially with longer patch cables.
Reception
The 2HP VCM is valued for its simplicity and utility in patching scenarios where a full mixer would be overkill. It excels at blending control voltages—such as combining LFOs or envelopes—without requiring power or rack space. Users often describe it as a module that "disappears into your rack until you need it," then becomes indispensable. While it attenuates audio signals slightly, this trade-off is accepted for its convenience and efficiency in CV mixing applications.
