Series/Parallel - It is possible to utilize various series/parallel'hook-up' topologies to increase the number of loudspeaker$ ----~--
driven on an amplifier. See diag. 4 for one example of a series/parallel hook-up topology. . _J_
Note: Mis-matching the speaker impedance such that it is below the minimum impedance rating of an amplifier channel can
damage the amplifier and degrade performance. If the application requires more than 2 speakers per amplifier channel ---+-
wired in parallel, a distributed line system should be considered. Also check your amplifier's manual for cautions and
recommendations.
Importance of Correct Polarity ("In-Phase/Out-of-Phase")- When two loudspeakers are wired with opposite polarity
("out-of-phase") relative to each other, the low frequencies of the loudspeakers cancel each other, even though the speak-
ers are "working hard." Trying to correct the lack of bass with an equalizer can damage your loudspeakers-- equalization
cannot correct polarity errors . Always make sure multiple speakers are connected in proper polarity . (See "Poor Low
Frequency Output" in the Troubleshooting section for instructions about how to detect and correct polarity problems.)
