AYRE DX-5DSD - Manual (Page 89)

Do not ever change these settings, as
this will adversely affect the sound
from the HDMI Audio Output or if the
LFE Mixdown mode is engaged.
The operation “Reset Factory
Defaults” will automatically change
these settings, requiring you to reset
the “Speaker Configuration” settings
for proper operation of the HDMI
Audio Output and LFE Mixdown
mode.
Dynamic Range Control
Sets the audio Dynamic Range Control (DRC).
DRC tends to make all sounds play back at a similar
loudness. This is useful when listening while others
may be sleeping, as it prevents the loud sounds from
playing back at a high level and it becomes easier to
hear the dialog during quiet scenes. Otherwise the
DRC should be turned off to hear the sonic
dynamics present in the original recording. The
available options are:
• Auto – Play at the dynamic range specified by
the disc. This option applies to Blu-ray discs
only. For other disc types no dynamic range
compression is applied.
• On – Turn on dynamic range compression.
• Off (default) – Turn off dynamic range
compression.
