Avrei dato qualsiasi cosa per farci io il sound check!

The subwoofers are powered by an integrated 8500 watt amplifier. With 110 subs that is nearly 1 million watts of potential power on tap just for the subs.
The amplifiers for the mid/high speakers, add another 30000 watts per amp, for a total of another 3 million watts of potential power.
We powered this test with a 1 MegaW generator so the system is capped by that. But a rough estimate is the test set-up was using between 40-60% of the generator capacity to power the set-up for the qual level testing. Everything in the system is horn loaded which allows for greater efficiency at higher levels.”
