Lynx Studio Hilo Version 5 Firmware - Manual (Page 8)

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.
When switching into DSD Mode to “Auto”, if Hilo is in
16-channel LT-USB mode, then a warning screen will
appear. As DSD requires a sample rate of 176.4kHz
available only in USB 8-channel mode, this screen will
prompt you to switch to 8-channel LT-USB mode.
Tap Yes and Hilo will automatically reset to LT-USB 8-
channel mode and be ready for DSD playback.
While DSD is playing, any page that has level meters will
show a DSD logo instead of the meters. As soon as DSD
playback is stopped, the level meter page will return.
1.3.3 Test Tone function
Intended for system testing and calibration, Hilo’s new Test Tone provides a 1 kHz audio signal which can be sent to
any output or combination of outputs. The tone level can be controlled in 0.5 dB increments from a new dedicated
screen. For reference, the same screen also shows the input levels coming into Hilo.
