audio in DoP V1.1 is automatically detected on either Hilo TBT input 1 & 2 or the selected Digital In Source. If DSD
is detected on both of these sources, priority is given to TBT 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.
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.
4.5.6 Test Tone Function
Intended for system testing and calibration, Hilo’s 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.
Using the menu button on the Output side (here selected
as Line Out), choose the output to which you want to send
the test tone.
Use the On/Off button to engage/disengage the test tone.
The initial level is set at -40 dBu. The fader and front
panel rotary control allow you to adjust the level in 0.5 dB
increments.
Multiple outputs can receive the test tone simultaneously.
Inputs Meters are shown to allow monitoring of any
signal being received by the Hilo.
