Redefining pro, the new ASTRO A40 TR headset and Mix Amp feature user customization to adapt to any environment. Ready for home use, LAN play, or the loudest pro tournament, you can transform the A40 TR from an open-back to a closed-back noise-canceling headset by swapping components like speaker tags, microphones, and ear cushions (sold separately in ASTRO Mod Kits). For serious live streamers, the Mix Amp Pro TR is re-engineered with all digital components for lag-free and interference-free operation. The included ASTRO Command Center software allows Pros and Live streamers to tune every input and output parameter of the Mix Amp Pro TR to precisely configure it for their specific setup.
