Listening experience
The DTS Studio Sound UI contains many controls for optimizing the audio experience on the Z1 G2. These controls have
been pre-set to sound best for a wide range of audio content. However, depending on the audio content or personal
preference, adjustment may be desired. After the controls are adjusted, it is always possible to return to the original
settings: use the Reset button found in the Advanced Settings tab.
There are two portions of controls in the Listening Experience tab: the Graphic Equalizer and DTS Studio Sound Audio
Enhancements. The Graphic Equalizer adjusts the gain of different frequency bands in the audio spectrum. The default
pre-set is a flat (ideal) frequency response. There are many other pre-sets for various music genres. Or the user can
define a custom Graphic EQ pre-set.

The Graphic EQ should not be considered as a volume control. The result of pushing all the sliders to maximum gain
could be increased audio distortion. This is especially true for the low frequency bands (125Hz and lower). If extra bass
is desired, either use the Bass slider in Audio Enhancements or connect an external subwoofer (to the orange jack in the
rear I/O panel). The Z1 G2 is acoustically tuned to be used with the HP Pulse Subwoofer.
The Audio Enhancement portion of Listening Experience tab controls the DTS Studio Sound effects. These are
psychoacoustic effects produced by digital signal processing. These effects can be enabled/disabled with the checkbox
next to "Audio Enhancement." These effects can be adjusted separately for three modes: Music, Voice, and Movie. These
effects apply to the internal speakers, headphones, and line-out.
Descriptions of the DTS Studio Sound effects are as follows:
Bass
Increasing this value will provide a greater TruBass effect (more low frequency information). Decreasing this value will
provide less of an effect. This is a psychoacoustic effect (not the same as increasing the gain of the low frequency bands
in the graphic equalizer).
Definition (Treble)
Increase the value of this control if the perception of clarity and acoustic space needs improvement. Decrease the value if
the high frequencies are too sharp.
Center
Center affects the volume of the center channel. Increasing this control will result in a louder center channel image.
Decreasing it will lower the center volume.
Space
Space affects the apparent width of the stereo image. The higher the value of this control, the louder the stereo space
effect.
Focus
Focus affects the apparent vertical position of the sound. Increasing this control will raise the elevation of the
soundstage. Decreasing this control will lower the elevation down to the physical level of the speakers.
