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.
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.
This amplifier has different loudspeakers outputs of 100V,70V and low impedance 4Ω/8Ω.
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,4Ω and 8Ω terminals must work with COM.
