Speaker wiring




						Part Number or description

LCD Monitors


	Wiring Speakers in Series Speakers in series double the nominal speaker impedance, ie. two 8 ohm speakers become 16 ohm . Typically used in band PA speaker boxes, nightclub speaker systems, DJ's systems and car audio systems.

	Wiring speakers in parallel Speakers in parallel halve the norminal speaker impedance, ie. two 8 ohm speakers become 4 ohm. Typically used in band PA speaker boxes, nightclub speaker systems, DJ's systems and car audio systems.


	Wiring speakers in series parallel Speakers wired in series parallel are used to maintain the same impedance as a single driver. ie. four 8 ohm speakers wired in this configeration represents an 8 ohm load to the amplifier. This arrangment substantially increases the total SPL of the system compaed to one single driver.

Wiring speakers in parallel for 100V line
Where several speakers are to be used at one time, on one circuit, it becomes necessary to use speakers fitted with line matching transformers. This is to overcome the effects of connecting speakers in pararllel and cable losses. The amplifier system generaly has an output voltage of 100 volts. This is then applied to the speaker transformers.

In this configuration the total wattage load on the amplifier is derived from adding all the line transformer primary tap ratings together. For examplem, 70 one watt speakers will have a total speaker load of 70 watts. Or alternatively, it is conceivable to connect 100 one watt speakers to a 100 watt, 100 volt line amplifier.
