DMT™ (Directivity-Matched Transition) ensures smooth coverage across the entire listening area. Advanced on-board DSP provides Intrinsic Correction™ voicing and advanced system management to further optimize performance.

Description

The K.2 Series can function as either the Main PA or as a Floor Monitor. Each model can also be flown, wall- or truss-mounted or placed on a speaker pole, either straight-firing or with 7.5 degree down-tilt. This flexibility makes it a smart choice for a wide range of live sound applications.

Two inputs (A and B) feature combo XLR-1/4″ connectors with input A offering a Mic/Line selection and input B offering Mic/Hi-Z selection, which is designed for connecting high-impedance signals such as guitars and other instruments. Additionally, channel 3 provides a 3.5mm TRS auxiliary input for connecting portable audio devices. With independent mic and line inputs, the K12.2 is a great choice for any singer/songwriter or solo performer with an instrument. You have independent control over mic and instrument levels, while the aux input provides backing tracks or incidental music between sets.

The highly efficient 2000W Class-D amplifier powers the 12″ woofer and 1.4″ titanium compression driver, which provide full-range audio (50 Hz to 20 kHz) with a sound pressure level powerful enough to ensure the entire audience can hear your performance. QSC’s Directivity Matched Transition (DMT) matches the coverage angle of the woofer at the crossover frequency with the horn pattern to ensure a uniform response across the coverage area (75° axisymetric). The Intrinsic Correction techniques ensure a smooth power response resulting in accurate performance in a wide range of acoustic spaces with little or no EQ. The K12.2 includes a power cord.
