QSC K12.2 Powered 12" PA Loud Speaker

The 2000 Watt power module delivers ample burst and  continuous power for the loudspeaker’s premium drivers. It has been designed with very low-noise fan cooling, enabling the enclosures to be used in settings where background noise must be kept to a minimum. Carefully tailored, subtle and sophisticated dynamics processing is used to protect the drivers from damage and the performance from distortion.

A pair of balanced combo XLR/F plus 1/4-inch TRS connectors with independent gain control are provided. The first is equipped with selectable MIC/LINE (Microphone or Line) level input while the second offers selectable HI-Z/LINE (High Impedance or Line) level input, specifically for musical instruments. Both inputs are connected directly to a pair of XLR/M throughput connectors so that the signals may be “daisy-chained” to another audio device. A 3.5 mm TRS input jack with independent gain control is also provided  for connection of sources such as smart phones, computers, and MP3 players.

In addition to the two throughput XLRs, a line-level output with the mixed signal from all inputs is also provided. (An optional security cover (K-LOC) may be installed to prevent unauthorized tampering of settings)
