Návod k použití QSC AUDIO MX 700

[. . . ] [. . . ] MXa rear panels feature our exclusive Level 1 Open Input Architecture, which allows the addition of input transformers, crossovers, power limiters, precision attenuators, and other signal processing accessories. An extensive set of protection features assure stable operation and reliability, even under the harshest conditions. MX Series Features · High-efficiency stepped linear outputs reduce amplifier cooling requirements and AC current draw by greater than 40%* · Independent power supplies on each channel for greater reliability (dual monaural on MX 2000a & MX 3000a, split secondary on MX 700 & MX 1500a) thermal performance · Power transistors direct­mounted metal-to-metal to heatsink for superior · Level 1 Open Input Architecture for cost­and space­saving signal processing accessories* · Independent DC, subsonic, ultrasonic , and thermal overload protection on each channel automatically protect amplifier and speakers · Patented Output Averaging short circuit protection · Automatic two-speed fan matches cooling capacity to thermal requirements. Rear-to-front air flow prevents rack overheating.
