The XFire 1024's references read like a "Who's Who" of 3D-sound standards: Via superior Sensaura technology the DMX XFire 1024 offers full support for A3D 1.0, DS3D, EAX 1.0 and EAX 2.0 bringing up to four speakers to life. Digital, whether in or out, with the DMX XFire 1024 you can do it. The S/PDIF digital out even guides AC3 streams through - courtesy of Dolby Digital. In addition the DLS 1.0 compliant wavetable synthesizer allows you to upload alternative sound sets, which can be used instead of the default 8MB sound set. Only the equalizer is capable of throwing the straight frequency paths off track before the end.
