BGM inputs

The voice alarm controller has 2 BGM inputs (see figure
3.3 and table 3.3). Each BGM input has a double cinch
socket. To these cinch outputs, a background music
source can be connected (e.g. a PLN-DVDT Plena
DVD Tuner). The signals connected to the L (left) and R
(right) cinch sockets are mixed to form a single input
signal.
