Muta Jovis is a 4HP switchable quad mute. The inputs are circularly normalled so a single input can be sent (and muted) to up to four outputs. Switches and LEDs that indicate channels that are outputting signal leave no doubt about the state of each channel. MJ was designed with gates/triggers in mind.
