Blood Cells Audio MUM Eurorack VCA & Mute Module

We say...

Cool combo of preamp, VCA and performance-friendly mute button in a compact 4HP package.

Manufacturer's description

Make-Up and Manipulate (MUM) is a combination of quality variable-gain preamp, clipping circuit, a VCA, and a momentary Pulse button for manually gating the signal on and off (with no clicks). Use it to amplify, attenuate, and gate anything from modular AC/DC signals, to contact mics and guitar, to the grimy voltage-starved output of a BCA Passive Mangle module - all in 4HP.

The Pulse button is fast-acting and performable: When the channel is latched into Off Mode, Pulse acts as a push-to-talk button, allowing your input signal to pass while the button is held. Conversely, when the channel is latched into On Mode, Pulse acts as a push-to-mute, killing all signal while held. A Pulse output jack mirrors the Pulse button's action, so you can simultaneously send 5V gates to other modules in the system, even as you tweak your signal within MUM.

Use the CV Input/Level section to control the channel level as you would with a standard VCA, or combine it with manual gates from the Pulse button.

The preamp's max gain is switchable between +10dB and +40dB, and has a 3-color LED for level-setting. The preamp’s high input impedance means it won’t steal the low-end from your contact mics and make them harsh, and is equally suitable for guitar.

There is also a switchable Clip circuit that is a combo of hard and soft clipping, as well as an option to flip between AC and DC-coupling from the front panel, avoiding a pesky jumper on the backside.
