BLACKBOX-01 is a limited-edition, handmade product limited to 1000 units. Each unit comes with it's own unique number identifier, printed on the top of the box.

Blast Guard lets you

Control the cues

Gunshots and explosions in CS2 can bury the quieter cues that tell you what happens next.

Blast Guard uses selective compression to give you control over the relationship between those loud effects and the subtle information underneath them, so you can hear everything in-game.

  • Lower the Loud reduces gunshots and explosions while leaving footsteps and other subtle cues untouched, decreasing brain fatigue over long sessions. 
  • Footstep Enhancer raises footsteps and subtle cues without changing the intensity of gunshots and explosions - if you never want to miss a sound cue again.

AceZone’s audio approach and design philosophy always grew from the demands of professional esports. Our A-Live stage headset has been used at events run by organisers including PGL, ESL and BLAST, where only the best noise-cancelling and mic-technology is acceptable.

BLACKBOX-01 extends that esports focus to a dedicated sound card. Portable, proven hardware, onboard settings and a visible Tournament Mode give players practical control over their audio as they move between LANs, bootcamps, and their home setup
