•
If audio is present on the 5.1 input, the Aux input is overridden.
•
If only L/R is present on the 5.1 input and audio is present on the Aux, the L/R is
overridden.
•
If there is no audio present on C/LFE, Ls/Rs, or Aux inputs, source from L/R.

Overview
The FS1 and XD1 offers four channels of DTS Neural Loudness Control—a loudness leveling device that
uses advanced psycho-acoustic and signal processing techniques to accurately detect and regulate the
perceived loudness of stereo and 5.1 sources. Using this feature, you can regulate audio without
creating the perception of being "squished" or compressed.
One of the important aspects of loudness control is
frequency compensation
, also known as loudness
shaping. Loudness studies dating back to Fletcher /Munson in the 1930s found that the human ear is
more sensitive to different frequencies at different loudness levels. The
Loudness Shaping
(
Frequency
Compensation
) parameter preserves the same perceptual frequency balance as the input signal, while
correcting the loudness to match a desired
Target Level.
