8.3.1 Rules for connecting loudspeakers

The amplifier outputs can be connected to a different number of loudspeakers. Rules for connecting: Ensure the total minimum impedance 6 Ω for each channel by combination

of serial and parallel wiring of loudspeakers. Overall power of combination of speakers must be equal or greater than

amplifier maximum output power. When needed, whichever loudspeaker from the combination can be

substituted by resistor with the same impedance (resistance) and power. Keep the polarity of speakers, so that the output signal from all speakers is

kept in phase.

8.3.2 Wiring examples

Number of speakers and their layout must be determined by project designer.

Any of the speakers in parallel connection (if there is more than 1 speaker) can be in regards to spatial requirements substituted with a resistor with equal impedance and power as the substituted speaker.
