Studio quality, road rugged, simple, reliable
We have been using these and the lower-watt models in 8 different portable PAs for 7 years now with ZERO problems. We rent audio systems (and lights) for music venues, corporate speaking events, NASCAR, political fundraisers... you name it. Our equipment must be bullet-proof, idiot friendly and great sounding.
The core of all our systems are QSC amps. There are other good amps out there. I have nothing against Crest or Crown... both great companies. Nothing compares to the sound-quality, superb flatness, high power with low weight like these.
>Pro-Connections for all types of speakers are clearly labeled.
>Circuit board face-down design has prevented numerous failures because of spilled liquids.
>Overload protection with LED displays provide obvious signs before danger.
>Best rack-mounting system
>Super strong but lightweight chassis
Our high-end line-array systems have all the modern gizmos and speaker compensation, but our daily bread & butter comes from smaller simpler systems.
Since most of our users are NOT tech-friendly, we make the simplest PAs possible with Mackie boards, QSC amps and Yamaha speakers. Zero failures in 7 years after hundreds of gigs, usually with renters who know nothing about audio equipment.
You can get fancier, but not better.
