Creative Labs Sound Blaster X4 7.1 channels USB

Sporting a fresh new look, the Sound Blaster X4 supports up to 7.1 discrete
and virtual surround with three different surround delivery options—
Super X-Fi Headphone Holography, Sound Blaster Acoustic Engine’s
Surround Virtualization, and Dolby Digital Live Encoding.
It’s also extremely versatile, featuring seven I/O connectors that works across
different platforms, from external microphones and headsets to PC, Mac,
gaming consoles, and even AV receivers.
This audio card not only features convenient direct controls on the device
itself, but also smarter ways to communicate online using our SmartComms
Kit, a suite of smart communication features—VoiceDetect and NoiseClean—
designed to simplify the way Windows 10 users take online work calls, or for
any in-game chat.
Plus, you are free to personalize your audio settings, including EQ
adjustments, microphone settings, and Acoustic Engine effects like Bass for
bigger audio punch and Crystalizer that helps improve the dynamic range of
your audio.
