Sound Blaster Audigy 2 ZS

Sound Blaster Audigy 2 ZS

The Sound Blaster Audigy 2 ZS (SB0350) improved upon the Audigy 2 by having a slightly improved signal-to-noise ratio (108 vs. 106 dB) and added built-in DTS-ES (Extended Surround) for improved DVD playback. The AC97 codec was removed from the ZS series entirely, using I²S on all outputs. The Audigy 2 ZS supports up to 7.1 speakers (although the 4.1 speaker configuration was still in reality only 4.0; a dedicated low-frequency-effects channel output was only available with 5.1 and higher, requiring the presence of a center speaker).
