4. INSTALLATION
4.1 Speaker connector
When combining several speakers/cabinets, you should bear
in mind the resulting overall impedance. Here are some brief
explanations about different kinds of connections:
Serial connection: The individual impedance values of the
connected speakers are added up. If two 4-Ohm speakers are
connected to one another, there is an overall impedance value of
8 Ohms.
Parallel connection: If speaker/cabinets with identical
impedance values are connected in parallel, the overall nominal
impedance is reversely proportional to the number of speakers,
e.g. if you connect two speakers/cabinets, the nominal impedance
is halved; if you connect three speakers/cabinets, the nominal
impedance is one third of the individual speakers impedance;
with four speakers, its one quarter, and so on. For example, this
way you can turn two 8-Ohm systems into one 4-Ohm system.
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. Dont lay output cables
near input cables.
Wiring options for loudspeakers are additionally explained in
the following illustrations and tables.

BA and BB series bass cabinets only support parallel
connections.
