QRumble
QRumble is a powerful low frequency enhancement algorithm that helps to compensate for loss
of bass that may result from compressed digital media such as MP3’s or WMA formats.
QRumble responds in real time to the varying nature of the input signal, automatically adjusting
itself accordingly. This is very different from the Equalizer, which is a static frequency processor.
The Equalizer does not monitor the input signal or perform self-adjustment.
The label QRumble Active appears in illuminated text when QRumble is enabled, and
QRumble Off when disabled.
Normalization
Normalization automatically adjusts the volume variations in various audio files or streams.
Quieter signals are amplified to match the level of louder ones, so that the listening volume
maintains a consistent level. This means that when playing files with various output levels, the
need to constantly adjust your speaker volume is minimized.
The label Normalization Active appears in illuminated text when Normalization is enabled, and
Normalization Off when disabled.
NOTE: If the pre-recorded volume of the source is too high, the playback might sounds ‘wavy’.
This is ‘as designed’ and can be minimized by turning off the Normalization for that particular
song.
UltraBass
UltraBass is a bass-enhancement system, which uses the way humans perceived sound and
signal processing to enhance bass quality of small loudspeakers.
3D Effects
Three separate 3D audio enhancement algorithms are provided to maximize the spatial
experience no matter what the combination of signal type and output hardware.
When 3D Effects are enabled, the audio processor will automatically choose the appropriate
algorithm (3D mode) according to your output configuration and the type of input signal. The 3D
Effects indicator LED’s on front panel and the indicators on the Effects Tab illuminate to show
which algorithm is active at any given time.
QXpander optimizes stereo input played over 2 speakers or headphones. When QXpander is
active it provides a wider sound field far exceeding physical position of the speakers.
QSurround optimizes a multi-channel source (e.g. a 5.1 channel DVD) to create “virtual”
speakers and immerse the listener in surround sound.
NOTE: The source must be a multi-channel in order for this feature to be activated (e.g. on 5.1
DVD playback, please make sure the software-DVD player is set to 6-channel output).
