PSG Audio K12A 1000 Watt Replacement Amplifier Module for the QSC K12

Onboard mixer with two combo XLR and ¼ inputs, and stereo RCA inputs, (three audio input sources); two direct channel outputs and single summed balanced output
Extensive DSP enhances system performance
DMT (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural dead or hot frequency zones.
Intrinsic Correction, first featured in our high-end line-array products maps 6575 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat band pass target. The result is a speaker that behaves equally well across the entire sound field.
DEEP and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
GuardRail protection protects both the amplifier module and your performance from unnatural and destructive clipping.
