AYRE DX-5DSD - Manual (Page 83)

Secondary Audio
Sets the Secondary Audio Program (SAP) mixing
option. Some Blu-ray discs contain a secondary
program, such as a director’s commentary or menu
sounds. This menu item allows you to mix the SAP
sounds into the primary audio. The options are:
• On – The Secondary Audio Program and menu
sounds are mixed into the primary audio. High
resolution primary audio will be converted to
normal resolution in order to mix with the
secondary audio.
• Off (default) – The Secondary Audio Program
and menu sounds are turned off. This setting
preserves the highest possible audio quality for
the primary audio.
It is recommended to turn the Secondary Audio
“Off”. This provides the highest sound quality for
the main soundtrack.
HDMI Audio
Selects digital audio output format from the HDMI
A/V Output. The options are:
• Auto – The audio format will be selected
automatically, based on communications with
the surround-sound processor.
• LPCM – Digital audio output will be Linear
PCM, and compressed audio bit streams will be
decoded by the player.
