Super Sound
• High-End 108dB HD Audio
* Product features may vary by model.

As the HD multimedia revolution continues to gain momentum, so too must hardware standards in audio quality. All GIGABYTE Super4™ motherboards offer excellent 7.1 surround sound audio backed by a proprietary converter that is able to achieve 108dB noise ratio (SNR) playback quality. This means that users will enjoy a better audio experience with lower levels of noise and hiss when enjoying the latest HD content.

108dB Signal-to-Noise ratio playback
All of GIGABYTE’s 2011 motherboards feature the Realtek ALC889 audio codec, or better audio solution to deliver high-performance, multi-channel HD audio. The ALC889 incorporates Realtek’s proprietary converter technology which is able to achieve 108dB Signal-to-Noise ratio (SNR) playback quality. SNR is a comparison of the amount of signal to the amount of noise, such as hiss, present in the signal (expressed in Decibels). A higher SNR equals a better audio experience. For example, 108dB, is a high audio specification, as this means the audio signal is 108dB higher than the level of the noise.
