The QSC K10 speakers generate up to a 1000 watts of power with a built-in Class D amp that’s perfectly matched for the best clarity. These speakers also Feature a built-in 2 channel mixer, so you can plug almost anything indirectly and mix your inputs with a minimum of fuss. So for simple gigs, you don’t even need a separate mixer. If additional inputs are required for more complex gigs, any mixer can be added; although the Touchmix 8 or 16 have been designed to work seamlessly with the system.
