Listening Mode Settings - Extron electronics SSP 7.1 User Manual

Listening Mode Settings

The SSP 7.1 provides a range of settings that refine the sound distribution for each listening
mode, depending on the decoding mode that has been selected.
Dolby Pro Logic II or IIx Music
Dimension control — This feature alters the ratio of L+R to L-R for two-channel input signals,
which adjusts the sound field towards the front or towards the back. The available settings are
Front
Center width control — Pro Logic decoding produces a single center signal that comes from
the center speaker. If there is no center speaker, a "phantom" center image is produced that is
split between the right and left speakers.
If right, left, and center speakers are present, center width control allows variable adjustment
of the center image so that is heard only from the center speaker, only from the right and left
speakers, or from all three speakers in varying degrees.
There are up to eight different settings, with each corresponding to a specific calculation
angle (F). When the setting is
, the sound is from the L/R speakers. The default setting is
7
NOTE:
Table 3.
Panorama control — This feature extends the center width control, so that all or part of the
center image can be heard from the surround speakers for a "wraparound" effect. The feature
may be
DTS Neo:6 Music or Cinema
Center image control — The center image control varies the amount of attenuation applied
to the left and right channel information of the input source that is used for creating the output
center channel effects. When it is set to
creating the center output channel of the DTS Neo:6 listening modes, is filtered back to the front
left and right output channels. This creates the effect of spreading the centralized audio signal
across all three front output channels. When this control is set to
intended for the center output channel effects is fully attenuated, allowing the center channel to
create a more centralized effect from the front channels.
