      ASUS HTPC Unique Features

      Absolute Pitch Hi-Fi

      Crystal-clear Audio with Reduced Electronic Noise

This effectively reduces electronic noise to ensure purer sound quality. Additionally, the gold-plated RCA stereo audio connectors are compatible with amplifiers without requiring additional connectors—making it simple to link PCs to home theater equipment.


      Tranquil Mode

      Super Silent for Multimedia Enjoyment
      The tranquil Mode can lower the noise from CPU and chassis fans instantly by up to 28%. Also, it dramatically boosts energy efficiency and cost-effectiveness. By lowering the noise generated by fans, users will be able to enjoy their movies and music in a more conducive environment.
