The BKM-48X is not equipped with decoders, but if

signals input to the BKM-48X.
Expansion of analog component inputs is also
possible.
Analog Input and Output Signal
Connectors
The BKM-48X is equipped with six input and six
output connectors. You can input two Y/R–Y/B–Y,

to the input connectors. The types of analog
composite signals that may be input vary depending
on the input adaptors installed in other input option
slots (see page 4(E)).
Floating System
Each input connector can be selected to either
floating or grounded mode by the switches on the
board (SW1 to SW6, shown in the figure on the right
