Question about TOA Electronics A912MK2 Amplifier
Is it the amount of amps im getting it confused with?
It is load resistance. set the amplifier switch to the resistance ( X amount ohms) to match your speakers. Although running 4 ohm speakers at the 8 ohm setting is louder, it will hurt your amp
most home/semi pro speakers are 8 ohm, while car speakers are 4 ohm. If you are doing a multi speaker pa/intercom install use your formula to calculate total load is 2 8 ohm speakers in parallel are four ohms . express them as fractions and add the denominator ie:8/1 +8/1 = 8/2 or 4/1 or 4. now connect that in series (add the top numbers)with another 2 speakers in parallel and you get back to 8 ohm load. repeat the same process over and over and you can hook up to 32 speakers to the amp without needing the 70 volt tap. hope this helped.
