3 System Installation
CAUTION: Before installing your system, make sure that
you have read the Important Safety Precautions at the
beginning of this manual.
3.1. Hub Installation
The AmpLINC Hub is a UL 2043 plenum-rated unit which can be
safely installed in the plenum space. SP Controls recommends
that the unit is secured in some fashion to prevent movement of
the unit if one of the cables is pulled during installation of an am-
plifier node.
For full UL 2043 (Plenum) compliance, the external power supply
should be placed in an area other than a plenum space.
3.1.1 Input Connections
The AmpLINC Hub accepts an unbalanced stereo input using
either RCA or 3.5mm plugs. The standard wiring is shown below.

indicators on the top of the Pucks will turn off.
