I hope this is not off topic, and comes under the category: "usage of specific music software or hardware". I am new to this community but have used other communities before.
I am playing live at the weekend in a hall of small size, no more than 100 people. We will be using a mixer/amp combo, specifically the
Yamaha EMX512SC. We have at our disposal
x4 100w passive speakers which for the purpose of this question I am assuming they are all
I have researched that running speakers in series you half the impedance. With this in mind I am looking at the specifications for our mixer/amp combo and I am concerned that we are not safe to use it.
According to the
Yamaha EMX512SC specifications:
Maximum output power: @4ohms 500W/ch Maximum output power: @8ohms 370W/ch (100V model), 350W/ch (120V model), 320W/ch (220-240V model)
Yamaha EMX512SC has output 2 channels. Is it possible for me to safely run these x4 100w speakers, using series or parallel wiring?
Note: We only plan to use this equipment for vocals and keyboards only, as we plan to use our guitar/bass guitar amplifiers.
Update, after comments/answers.
Unfortunately I do not have exact model numbers for the speakers. Two of the speakers are carlsbro, they look exactly like the ones in this picture, but 100w not 150w.
End Result. We got to the venue and it was a lot smaller than what we had anticipated. After looking at both sets of speakers we found that one pair was actually 16ohms 100 watt. The other pair had no markings on at all except that they were 100w, so we still had mystery speakers in terms of ohms! These speakers however had accompanied the mixer/amp and they had been run together previously. We ending up going with just these speakers, each had their own channel.
