Connection illustration:
This amplifier has different loudspeakers outputs of 100V,70V and low impedance 4-16Ω.It’s only possible to use one output at the same time,connecting more than one may damage internal parts of the amplifier.Each of 100V,70V,4-16Ω terminals must work with COM.
100V line output:
This system is most commonly used in for PA system. Only use 100 V line loudspeakers with transformers. All loudspeakers are wired in parallel and the sum of their power must not exceed the rated output power of the amplifier. It is advisable not to load the amplifier at more than 70% of its rated output power when using music sources.
70V line output:
This system is common in the USA,it operates on the same principles as 100 V line except that at rated output power the amplifier has 70V RMS on its output terminals.
4-16Ω low impedance output:
This output allows connection of low impedance loudspeakers without transformers,when two or more loudspeakers are used ensure that they are wired in such a way in Series,or in Parallel,or in Series & Parallel Combination that total load impedance remains between 4Ω and 16Ω.
