Phoenix Audio Quattro3 USB and Smart Interface MT303 - Manual (Page 6)

Plastic arch is installed
The Quattro3 was designed to conceal any cable connection below the unit. When connecting
the Q3, you can choose to run its cables discretely through an opening in your table or more
traditionally, on the table itself.
The Q3 arrives from the factory with its wiring slot sealed by a plastic cover. This should be
used for running the wires discretely under the table.
To run the wires on top of the table, unsnap the plastic cover and install the plastic arch
that is included with the unit. Make sure you slide the arch from below the hole and push its
sides in until you feel a click.
