A few years ago, QSC introduced a new amplifier platform of four-channel DSP power amplifiers featuring Flexible Amplifier Summing Technology\u2122 (FAST). Today this technology can be found in PLD, CXD, CX-Q as well as DPA and DPA-Q Series.<\/p>\n\n\n\n<p>This ground breaking FAST (Flexible-Amplifier-Summing-Technology) allows QSC amplifiers to operate more efficiently across a wider range of loudspeaker loads than what is traditionally possible. By incorporating novel Class-D control circuitry, the user can combine multiple amplifier output channels to improve power transfer into virtually any load.<\/p>\n\n\n\n<p>Unlike traditional amplifiers which are designed to deliver the highest efficiency (and power) at a single load impedance (e.g. 4 ohms, or 8 ohms), QSC\u2019s amplifiers with FAST allow the user to select an output stage configuration that best matches the requirements of their specific load. By allowing the user the flexibility to combine amplifier output channels in various bridged, parallel, and bridge\/parallel modes, the amplifier can be optimized for high voltage or high current delivery. For example, bridging two channels will give you greater voltage swing optimized for higher impedances (8-16 ohms). Paralleling two channels will give you greater power optimized for lower impedances (2-4 ohms). And that\u2019s not all, QSC\u2019s FAST amplifiers also offer the ability to combine three (or even four) channels into parallel mode to achieve ridiculously high current at low impedances (1-2 ohms).&nbsp;Then, you could also bridge-parallel all four channels to achieve 8000 watts of dynamic power optimized for a 4-8 ohm load.<\/p>\n\n\n\n<p>Hope you got interested?
