QX300A 2X 150W 1RU -1/3 SPACE COMMERCIAL POWER AMPLIFIER AUTO LOAD SENSING: 4-16 OHM, 70V-100V LNE

DESCRIPTION

QUEST QX-300 SERIESCOMMERCIAL POWER AMPLIFIER

The QX-300 series amplifiers take commercial audio to a new level. The superior Class-D technology combined with small form factor make the QX-300 series the perfect solution for any commercial or industrial application. Wall and table mount options offer more flexibility, 10 units can be mounted in 3RU, achieving extremely high power to channel count for density.

UMAC™ Class-D technology delivers unequalled audiophile specifications, including the highest dynamic range and the lowest distortion performance of any comparable pro audio amplifier. This makes the QX-300 Series suitable for pro audio applications and for use in Hi-Fi and AV products.
