2.1 Speaker connection
GEO S12 and LS18 is connected with Speakon NL4FC plugs (not supplied). A wiring diagram is printed
on the connection panel located on the back of each cabinet. The 4 pins of the 2 Speakon sockets
identified in / out are connected in parallel within the enclosure.
Either connector can be used to connect amplifier or to link to an additional Geo S12 cabinet or to link to
an optional LS18 (if present). Therefore, a single 4-conductor cable can connect two amplifier channels
to various Geo S12 and/or Sub Bass.

2.1.3 Configuring Geo S12 for Passive or Active Mode
 Remove the six TORX screws that hold the connector panel (figure next page);
 Remove the connector panel so that filter WAGO connectors become accessible;
 In Passive Mode, connector A (from filter) should be inserted in connector B (PCB
“Passive In”), and Connector D (“Passive Out”) should be connected to speakers via
connector C.
 In Active Mode, WAGO Connector A (from filter) should be directly connected into
speakers via connector C (PCB connectors B & D are then unused).
