Detalii
Crowns XTi models of amplifiers defines the standard for portable PA systems with unmatched performance, technology and power-to-the-people affordability that delivers the goods night after night without even breaking a sweat.
Innovations like integrated DSP that allows you to quickly and easily configure crossovers, EQ, limiting and delay, along with tools like a pink noise generator, subharmonic synthesizer, and universal tracking switch-mode power supply, which reduces power draw and waste heat. And as the first Crown amps to use Icepak thermal modeling software, they are at the top of their class when it comes to thermal efficiency and lightweight portability.
