DSD AND MQA OPERATION
DIRECT STREAM DIGITAL (DSD) PLAYBACK
AiOS is capable of playing native (not DoP) DSD files up to 512 via both wired Ethernet and wireless
Wi-Fi inputs as well as from the USB/SD inputs. You can also choose to access a computer that is
connected wirelessly to your network. If using Wi-Fi as your network connection, it is recommended
to use a 5 GHz router and have a very robust signal at AiOS' location.
However, this adds another potential interruption in the signal path when playing large files, such as
DSD, etc. For the fastest and most reliable playback, a wired Ethernet connection is recommended
to both AiOS as well as to your computer(s).
