Behringer Ultrabass BB410 - Manual (Page 8)

8 ULTRABASS BB410 User Manual
If four or more speakers/cabinets need to be connected, this can be done using
a serial parallel connection. With four speakers with an impedance value of
4 Ohms each, the resulting overall impedance does not change.
◊ Whenever possible, try to use thick and short speaker cables to
minimize power loss. Don’t lay output cables near input cables.
Wiring options for loudspeakers are additionally explained in the following
illustrations and tables.
