Onboard audio
Once again the Realtek ALC1200 is used for this board. The usual combination of 5x AUX + 1x Toslink / Optical S/PDIF provides sufficient sound. It offers a maximum of ten DAC channels supporting simultaneous 7.1-channel playback, as well as two independent stereo output channels (multiple streaming) via the front-panel stereo output (HD audio) with up to 110 dB signal-to-noise ratio (SNR). Two stereo ADCs are also integrated, realizing multiple analog audio inputs including a 102 dB SNR stereo line-in and a microphone input including microphone arrays with Acoustic Echo Cancellation (AEC), Beam Forming (BF), Noise Suppression (NS) and Far Field Voice Pick up (FFP) software functions.
For a detailed breakdown of the ALC1200, it’s worth checking out Igor’s basics article:
If you prefer audio-visual irradiation to reading texts, you can also watch the matching video:
The ALC is better than its reputation, but it also has some distinct disadvantages. The codec itself is absolutely fine, and a blind test will initially reveal a slightly higher noise floor at most, but this also depends heavily on the external circuitry and the selected gain. It is definitely a modern chip, although it is of course exactly one price and performance class below the ALC1220. The latter can handle higher impedance headphones, at least on the front audio, which definitely doesn’t work with the ALC1200.
