The 2.0m A40 Inline Mute Cable, otherwise known as the Console Cable or Mute Cable, allows one to mute outgoing voice communication to the A40 headset.
The cable has 2 different size ends, a 4 pole and a 5 pole. The pole connection goes into the headset, and the 4 pole connection goes into the MixAmp Pro or the PC Splitter.
Works with A40s Gen 2 and beyond.
