Audio Note DAC4.1x Balanced Owner's Information page 9

Special Note – Make sure that all connections are tight and clean. For
best results use good quality audio interconnects. Although it is
perfectly acceptable to use cables manufactured by other companies,
for best results and performance, we recommend our own Audio Note
(UK) range of interconnects and loudspeaker cables. For further
information, please consult your nearest Audio Note (UK) dealer, or
alternatively please feel free to contact us directly.
Inputs The DAC4.1x Balanced is equipped with two digital inputs, consisting
of one single ended RCA socket, and one balanced XLR socket. Only
connect one input, as it is not possible to use both inputs
simultaneously.
Mains The DAC4.1x Balanced utilizes an IEC 320 mains inlet socket. Use the
supplied mains cable to connect the unit to the local mains supply.
The mains fuse is located in a separate fuse holder, situated below
the mains inlet socket.
Ground Post A ground post is provided for connection to the ground terminal
located on the following pre amplifier, or the preceding CD Transport.
If, after all connections have been made, you experience any ʻhumʼ
problems, experiment with linking the ground posts / terminals with a
short length of wire.

of two pairs of colour coded RCA / Single Ended sockets.
