2HP VCM
A 2HP Eurorack module that works as a passive, three-channel voltage-controlled mixer. One CV input controls the level of all three channels at once.
Overview
The 2HP VCM is a Eurorack module made by 2HP. It is a compact, passive mixer for combining multiple signals directly in a modular setup. It has three input channels and one summed output. A single CV input controls the level of all three channels at once. It needs no power, so it can blend LFOs, oscillators, noise or envelope generators without using up any additional power headroom.

Design
The VCM is a passive circuit: three logarithmic potentiometers wired into a passive summing network. With no active parts, it needs no power and still allows direct, voltage-controlled blending of signals. The price of being passive is that the module slightly attenuates the signal and may roll off high frequencies, especially with longer patch cables.
Reception
The 2HP VCM is valued for its simplicity in patches where a full mixer would be overkill. It does its best work blending control voltages, such as combining LFOs or envelopes, without needing power or much rack space. Users often describe it as a module that "disappears into your rack until you need it," then becomes indispensable. It attenuates audio signals slightly, and that trade-off is accepted for its convenience in CV mixing.
