Coax Input
Connect a coax digital signal to the yellow phono socket. Select the coax input indicated by the red
source light.
Optical Input
Connect an optical digital signal to the TOSLink socket. Select the optical input indicated by the
green source light.
SD USB Input
The standard definition (SD) USB input allows for music playback up to 16 bit 48Khz. This input
does not require any drivers and will be compatible with nearly all mobile phones / tablets and other
source components with USB connection. ( USB drives and USB memory sticks / cards are not
supported ).
Using an OTG (on the go) USB cable or the AppleTM Camera Connection Kit Hugo can be
connected directly to a phone or tablet.
Select the SD USB input indicated by the yellow source light.
HD USB Input
The high definition (HD) USB input is the highest quality method of digital playback. This input is
asynchronous and uses Hugo’s own highly accurate clock circuit. This input will support 384Khz
PCM/DXD and also DSD64 and DSD128 in DoP format. No drivers are required for AppleTM and
AndroidTM devices but for Mirosoft WindowsTM you must firstly load the drivers on the supplied CD
or download them from our website.
Using an OTG (on the go) USB cable or the AppleTM Camera Connection Kit Hugo can be
connected directly to a phone or tablet.
Select the HD USB input indicated by the white source light.
Headphones
Up to 3 sets of headphones can be connected at the same time to share the listening experience.
There is one larger 6.35mm jack socket and two smaller 3.5mm sockets. The high current output
stage will work with headphone impedances as low as 4 ohms or up to several hundred ohms so
there are no restrictions on headphone type or choice.
Charging
Plug in the supplied wall power adapter to charge Hugo. The bright white charge light will
illuminate through the lens. When fully charged (approx 5 hours) the charge light will switch off. It
is safe to leave the power adapter connected continuously to charge and power Hugo. The charge
status is indicated by a colour changing light under the lens. Blue is fully charged and this will
change through green to red as the batteries discharge. When there is no power left the light will
flash red and the output will mute. Please recharge when this happens.
Sample Frequency Lights
Each digital sample frequency received will cause Hugo to illuminate different colours to indicate
correct operation. The sequence is as follows:-
Red –44KHz, Orange –48Khz, Yellow –88KHz, Green –96KHz, Light Blue –176Khz, Dark Blue
–192KHz, Light Purple –352Khz(DXD), Purple –384KHz(DXD).
White indicates DSD operation at either DSD64 or DSD128.
Crossfeed
There are 3 crossfeed modes that enhance the listening experience to give a more spatial ‘out of the
head’ stereo sound field. Using advanced filtering and delay the normal headphone stereo image is
