he Q4audio DPF series is a new breed of advanced professional power amplifiers incorporating low weight and premium audio performance. The newest technology switching CLASS D output stage and high efficiency resonant power supply in an aluminium chassis optimise sonic performance, reliability and portability. Unlike many other lightweight amplifier designs, the DPF series has high energy reserves on both the primary and secondary side of the high frequency power transformer giving it massive low-end response.

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 PIM-SIM1 input module 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.

Minimum sample frequency selection. Protection against over-dissipation, open or short circuit and HF or DC at the output. The amplifier will remain in protect mode with the power supply shut off in case of undervoltage at the mains input. Outputs on touch proof Neutrik® Speakon connectors. The individual channel and bridge output connectors have integral sensing inputs for the EFL circuit. High efficiency ZCS/ZVS switchmode power supply for minimum weight and low electromagnetic emission. Extensive power line filtering for minimal interference. Provision for remote AC power control. 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.
