I traded for a set and used them at my show Nov 1st.
I was using a Carvin 12 channel 1000watt powered head with the SP4s.
The sound was great but it shut off on saftey overload a couple times. The Carvin has 3 seperate amps, two for the mains(stereo) and one for the monitors. I was using two 12 inch monitors. I was not miking anything.
Any Idea what was wrong.

Hi Bill,
The peavey SP4 speakers are 4 ohm. If you were running them on one channel it would be equal to 2ohms or less. This could cause that carvin to thermal and shutdown.

| That is correct. Two four ohm speakers equal a 2 ohm load on the amp. The amp may be rated for a minimum 4 ohm load. |

I checked the back of the amp, it says 333 watts per per amp at 4 ohm. On the front it has a switch where you can send 1000 watts mono or 333 per amp as per three amps, one being for the monitors.

| What about your monitors? Were they 4 ohm in parallel? (2 ohm load)...or just maybe the total load from all four speakers was enough to overheat the amp....regardless of what the ratings were??? |

We played last nite. I backed the main output from 3/4 to 1/2 and turned the Channel Vol up and it worked fine. I don't understand it but it worked.
