	Figure 6.5 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.
