Audio Director
Allows you to define how sound is directed to devices. There are two
modes to select: Classic and Multi-Stream.
■ Classic mode - Emulates the behavior of Microsoft Windows XP, where
sound is heard either on the speakers or on the headphones, but not
both at the same time. To select Classic mode, click on the
corresponding icon.
■ Multi-Stream - Different sounds can be played on speakers and
headphones simultaneously. To select Multi-Stream mode, click on the
corresponding icon.
Two “Play” buttons allow you to play separate sounds in both modes:
■ When the red Play button is pressed, a sample sound is played on the
headphones.
■ When the blue Play button is pressed, a different sample sound is
played on the speakers.
In Classic mode, if the headphones are plugged in, both red and blue
sounds are heard from the headphones and if they are unplugged, both red
and blue sounds are heard from the speakers.
In Multi-Stream mode, the red sound is only played on the headphones
and the blue sound is only played on the speakers.
SmartEQ and 3D setting
On this page allow you to customize your listening experience by selecting
different profiles for headphones and speakers.
The smart equalizer (EQ) has five presets that automatically enhance the
sound quality of music or voice communications. The preset options
include: Jazz, Dance, Concert, Classical, and Voice. Each preset has been
optimized for the fullest sound experience. For example, the Classical
preset emphasizes the middle range of notes while the Dance preset
emphasizes the bass end of notes. Selected devices and profiles are
denoted by highlighted icons.
