Remove every BGM jumper found on the amplifier modules you wish to connect to this module.
Next, connect the BGMs to each section. For that purpose, connect the included cables marked on the printed circuit
board as WI102 and WI107 (Indication nr.2) to the two amplification modules you wish to use. Observe following figure:
The ground pins of WI102 and BGM OFF must be the same, so please follow the above diagram carefully. If you connect it
the other way round, the module would not work and possibly damage the selected BGM Input Module.
The connection of section B follows the same scheme. Connect WI107 of section B to BGM OFF on the chosen amplifier
module.
Following the next diagram, connect the volumes for each section. These are the included cables marked as WI103 and
WI109 for section A and B respectively. (Indication nr.3). Connect them to the corresponding amplifier modules.
If this cable is accidentally connected the other way round on the amplifier end, the filter of the MSB2 would work
inversely as marked on the printed circuit board: ON would be OFF and vice versa. The connection of section B follows the
same scheme. Connect WI109 of the MSB2 to the HPF of the corresponding amplifier module.
Connect the data bus (Flat 20-way cable) to the connectors marked with nr.4 in the next figure..
