Noise Engineering Muta Jovis

Switchable quad mute with circular normalling

4 HP Eurorack module

Muta Jovis is a simple but powerful utility: four independent mute channels in just 4HP. Each channel has a toggle switch that either passes the input signal to the output or connects the output to ground. LEDs confirm which channels are active. The inputs are circularly normalled, meaning a single patched input cascades through all four channels — patch one source and mute it to up to four destinations. Designed primarily for gates and triggers, it works equally well with audio and CV. MJ functions as a passive module (no power required for muting), though the LEDs need power to illuminate.

Features

  • Four independent mute channels with toggle switches
  • Circular input normalling — one input feeds up to four outputs
  • LED indicators show active (unmuted) channels
  • Passive mode — functions without power (LEDs do not illuminate)
  • Unbuffered mult when all channels are open
  • Muted outputs connect to ground (not floating)
  • Input/output range: -10V to +10V
  • Only 4HP wide

Controls & Jacks (16)

  • Mute 1— Toggle switch for channel 1. Left position mutes the signal; right position passes the input to the output.
  • Mute 2— Toggle switch for channel 2. Left position mutes the signal; right position passes the input to the output.
  • Mute 3— Toggle switch for channel 3. Left position mutes the signal; right position passes the input to the output.
  • Mute 4— Toggle switch for channel 4. Left position mutes the signal; right position passes the input to the output.
  • LED 1— Indicates channel 1 is passing signal (unmuted).
  • LED 2— Indicates channel 2 is passing signal (unmuted).
  • LED 3— Indicates channel 3 is passing signal (unmuted).
  • LED 4— Indicates channel 4 is passing signal (unmuted).
  • In 1— Input for channel 1. Normalled to In 2 when nothing is patched to In 2 (circular normalling).
  • In 2— Input for channel 2. Normalled to In 3 when nothing is patched to In 3 (circular normalling).
  • In 3— Input for channel 3. Normalled to In 4 when nothing is patched to In 4 (circular normalling).
  • In 4— Input for channel 4. Normalled to In 1 when nothing is patched to In 1 (circular normalling).
  • Out 1— Output for channel 1. Outputs the signal from In 1 when unmuted, or connects to ground when muted.
  • Out 2— Output for channel 2. Outputs the signal from In 2 when unmuted, or connects to ground when muted.
  • Out 3— Output for channel 3. Outputs the signal from In 3 when unmuted, or connects to ground when muted.
  • Out 4— Output for channel 4. Outputs the signal from In 4 when unmuted, or connects to ground when muted.
