he Q4audio DPI series is a new breed of advanced professional power amplifiers incorporating our latest technology CLASS D output stage for premium audio performance. The rugged steel chassis and conventional power supply based on a low flux toroïdal transformer make it a perfect match for applications where portability is not a premium requirement.

Features Switching class D output stage. Fully symmetrical and balanced modulator for unsurpassed accuracy and cross channel separation. Open input architecture for future expansion. The standard input module PIM-SIM1 provides: Inputs on Neutrik® Combo connectors or Phoenix screw terminals. Parallel link outputs on XLR-3M for easy routing of multiple amplifiers. Selectable high pass filters with 30 and 50Hz second order high pass filter characteristic. Instant recovery circuit eliminates stitching of the output when recovering from clipping or overload. EFL® (Extended Feedback Loop) technology makes it possible to take the feedback for the amplifier right from the loudspeaker terminals, offering unprecedented control of the loudspeaker, independent on loudspeaker cable length. The amplifier can be used as a normal amplifier without any inconveniences simply by not connecting the EFL sense inputs. Selectable clip limiter with selectable response time. Minimum sample frequency selection. Protection against over-dissipation, open or short circuit and HF or DC at the output. Outputs on touch proof Neutrik® Speakon connectors and high current Phoenix screw terminals. The Speakon output connectors have integral sensing inputs for the EFL circuit. Low flux toroïdal power transformer with thermal sensing. Output power of the amplifiers will be reduced in case of overheating. Overheating of the transformer is unlikely to occur, even with highly compressed music. Extensive power line filtering for minimal interference. Soft start minimises current surge on power-on enabling multiple amplifiers to be switched on simultaneously from the same wall socket. High efficiency cooling system. The power transistors are directly mounted onto individual heatsinks, eliminating the high thermal resistance of electrical insulators. This reduces component temperatures and extends the life of the power components. Two temperature-proportional speed fans for quiet operation.
