Kratak opis

With innovations designed to simplify your life and rock their world. 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.

HiQnet USB Connector: Type B, connects to a HiQnet network.

Protection

XTi-Series amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature; chain destruction phenomena; excessive output current, input overload damage; and high-frequency blowups. They also protect loudspeakers from input/output DC, large or dangerous DC offsets and turn-on/turn-off transients.
