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 dierent frequency bands in the audio spectrum. The default

pre-set is a at (ideal) frequency response. There are many other pre-sets for various music genres. Or the user can

dene 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 eects. These are

psychoacoustic eects produced by digital signal processing. These eects can be enabled/disabled with the checkbox

next to “Audio Enhancement.” These eects can be adjusted separately for three modes: Music, Voice, and Movie. These

eects apply to the internal speakers, headphones, and line-out.

Descriptions of the DTS Studio Sound eects are as follows:

Bass

Increasing this value will provide a greater TruBass eect (more low frequency information). Decreasing this value will

provide less of an eect. This is a psychoacoustic eect (not the same as increasing the gain of the low frequency bands

in the graphic equalizer).

Denition (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 aects 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 aects the apparent width of the stereo image. The higher the value of this control, the louder the stereo space

eect.

Focus

Focus aects 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.

HP recommends Windows.
