The QSC DPA 4.2 from the renowned QSC DPA series of power amplifiers represents best in class advancement in amplifier design and construction. QSC DPA amplifiers provide incredibly efficient and extraordinarily powerful amplification to drive multiple audio channels. These power amplifiers from QSC have advanced digital processing capabilities inbuilt and deliver optimal sound power while being rack space efficient.
The QSC DPA 4.2 is a four-channel amplifier, delivering 400 watts to each channel at 8Ohms.With its onboard DSP, allowing us to combine amplifier channels in different, technically desirable ways to drive huge range of speaker systems. These power amplifiers are highly efficient ensuring electricity costs are kept to a minimum while providing incredible power and processing to drive high end QSC loudspeaker systems.
The proprietary Flexible Amplifier Summing Technology™ (FAST) combines and distributes the available amplifier power in different permutations and combinations across one, two, three or all four channels. This feature enables QSC DPA Series power amplifiers to drive and bi-amp (for example) two numbers of SC 423 passive screen channel QSC cinema system or a single SC 423 along with a QSC cinema subwoofer; or two QSC SB 5218 or equivalent QSC subwoofers with ease.
DPA amplifiers are built around various energy efficiency and conservation strategies. One such example is the useful multi-stage sleep mode which ensures energy optimization without degradation of amplifier performance.
The QSC DPA 4.2 is much more than just a QSC power amplifier. It is a powerhouse with ultimate Digital signal processing capabilities. Housing DSP and amplification unit in the same box ensures dynamics processing and protection circuitry to be incredibly coherent and superior.
The onboard DSP has four channels of intrinsic correction, crossover settings, parametric equalization and dynamics processing – All parameters required to fine tune a cinema speaker system.
With an intuitive user interface in the front, Programming the QSC DPA 4.2 amplifier is an easy task. There is also the additional option of using “Amplifier navigator” software from QSC to programme and optimize the amplifier using USB connectivity.
