AYRE DX-5DSD - Manual (Page 86)

Coaxial/Optical Output
Sets the output format for the (AES/EBU) Digital
Audio Output for use with Dolby Digital and
DTS-compatible surround-sound processors. The
options are:
• LPCM – Creates downmixed two-channel
digital audio output. However, no external
converter will outperform the one built into the
unit that drives the Analog Audio Outputs.
• Bitstream (default) – Passes audio as compressed
bitstream format to the receiver/amplifier.
Choose this setting if your receiver/amplifier is
capable of decoding Dolby Digital and/or DTS.
Certain audio discs will achieve higher sound
quality with this selection set to “Bitstream”. This
allows pre-emphasized CDs to be equalized with
the high-quality minimum-phase digital filter built
into the internal Ayre D/A converter and
connected to the Analog Audio Output.
You may also use this setting when connecting to
a very old surround-sound processor that does
not accept an HDMI audio connection. There is
no reason to ever select “LPCM”.
LPCM Rate Limit
Sets the maximum Linear PCM output frequency for
the AES/EBU Digital Audio Output. Higher
sample rate material will be down-sampled to stay
within the maximum rate. The player does not
up-sample audio to higher sample rates. The options
