PA setup help...speakers & ohms

[baba]

Looking at Yamaha's EMX5000-12 powered mixer.

Scenario:

Provides 500W @4ohms mono out of left jack
Provides 500W @4ohms mono out of right jack

I want to daisy chain two of the Yamaha S115V (8ohms) speakers out of left jack. Does this equal a 4 ohm load, hence 500W @4ohms over the two speakers?

I want to daisy chain two OR three SM15V (8ohms) monitors out of right jack. With two am I at a 4 ohm load, hence 500W @4ohms over the two monitors? Can I add a third monitor to the daisy chain or will this drop it past 4 ohms and trash my powered mixer?

Thansk for any wisdom.

yeah you can only daisy chain 2 8 ohm cabinets per side with that amp (that will give a 4 ohm load per side BTW)
running three 8 ohm cabs will give you a net impedance of 2.67 ohms and will most likley fry the amp and void your warranty.

That's what I needed to know. Thanks.
