Note: Do not turn on the unit until all connections have been made.
You can use either the unbalanced (RCA/Phono) or balanced (XLR) outputs of the DacMagic.
The XLR output is preferable for long connections if your amplifier features balanced XLR inputs. It can better reject noise and interference in the cable. It is possible to use the RCA phono connections and the XLR balanced connections at the same time, e.g. for connecting to different amplifiers or multi-room operations.
