DSD Mode

DSD support was added with Hilo Firmware revision 5.
This allows Hilo to play DSD audio files received via USB, AES-3 or S/PDIF. Hilo supports the recently adopted DoP V1.1 standard
which is a method for transferring DSD audio over PCM frames. Playback of DSD using this method is provided by a growing
number of software vendors including Channel D and Audirvana for Macintosh, and JRiver Media Player for Windows.
Using the DSD application of your choice, connect your computer using the USB or Digital Input (AES IN; S/PDIF COAX IN or
S/PDIF OPT IN). Before playing, make sure the DSD Mode button is set to Auto. In this mode DSD audio in DoP V1.1 is
automatically detected on either USB input 1 & 2 or the selected Digital In Source. If DSD is detected on both of these sources,
priority is given to USB input 1 & 2.
NOTE: When the DSD Mode is set to Off, incoming data will be processed as standard linear PCM data always. If DSD audio is
received in this mode, low volume noise will be played.
DSD Routing: Upon detection of incoming DSD audio, the signal is automatically routed to the Line Outputs, Monitor Outputs, and
Headphone Output. Routing to the remaining outputs of Hilo is not affected.
The LT-USB that comes with Hilo has two modes of operation:
•
16 Channel operation – 16 input and 16 output channels at sample rates to 96 kHz.
•
8 Channel operation – 8 input and 8 output channels at sample rates to 192 kHz.
8 channel operation is the default.
Clicking on the button will toggle Hilo between 16 channel (96 kHz
maximum) and 8 channel (192 kHz) modes. You should not change this
mode while an audio application is utilizing Hilo. This control resets the
LT-USB and all audio will stop. When you press the button, you'll see
this warning screen:
Once your audio application is closed, you may press the Yes button and
the channel mode will change. You will now see the appropriate number
of record and play devices in your audio applications and operating
system.
Note: if the LT-USB card is removed, then the LT-USB Mode button will
no longer appear.
