A mixture of hardware, software, and tuning, SonicMaster was developed with the clear goal of giving you the best notebook PC audio. A professional codec ensures precise sound performance; while an optimised amplifier, larger speakers and resonance chambers deliver powerful audio output and deeper bass. Additional signal processing helps fine tune the hardware, filtering noise and improving clarity so you can enjoy unrivalled audio on your X540. ASUS X540 features round speakers that maximise every cubic millimeter of available chassis space to give you better low frequency performance and reduced noise. The extra-large 19.4cc chamber provides superior bass and excellent sound clarity. To customise audio settings to suit your own preferences, ASUS AudioWizard has five selectable modes. Music mode brings your favorite songs to life, while Movie mode provides a true cinematic experience. Recording mode gives dynamic and crystal-clear recordings, and Gaming mode adds a new dimension of enjoyment to your favorite games. Finally, Speech mode makes voices clear and powerful. ASUS X540 has a solid and lightweight chassis that weighs just 1.9kg - ideal to take with you when you're out and about. Its premium brushed finish turns heads and makes sure that you stand out from the crowd. To ensure only the very best images, ASUS Splendid Technology has colour temperature correction to reproduce richer, deeper colours. It features four visuals modes which can be accessed with a single click. Vivid Mode optimises contrast for browsing photos or watching videos and movies; Eye Care Mode reduces blue light levels and is ideal when you're reading for long hours. Normal Mode has been tuned for daily tasks; while Manual Mode is for advanced colour adjustments.
