Connecting low impedance loudspeakers

Connect low impedance loudspeakers to the 4 Ohm/0 terminals. This output can deliver the 

rated output power into an 4 Ohm load. Connect multiple loudspeakers in a series/parallel-

arrangement to make the combined impedance 4 Ohm or higher. Check the loudspeaker 

polarity for in-phase connection.
