With the Dolby Digital 5.1 Decoder and the BlasterX Acoustic Engine, Katana delivers an impressive audio experience for games and films. This audio system combines our most powerful 24-bit D/A converter with a highly advanced 5-driver system. Thanks to the Tri-Amplification design, where each of the 5 drivers is powered by DSP-controlled amplifiers, Katana provides extremely precise sound across all frequency ranges.
