Amplificador powersoft digam 15022 unidades conservados funcionando 100%Valor por unidade.The Powersoft D1502 is a professional power amplifier designed to meet the most stringent requirements of professional users in concert touring, sound reinforcement and professional fixed installations. Designed by Powersoft R&D team the D1502 is exclusively built in Italy with internal components selected for premium quality and proven durability. Each modular subassembly is pre-tested, and the assembled D1502 receives a rigorous 48 hours burn-in before through final check-out on precision test equipment for total quality control. The D1502 incorporates the legendary patented Powersoft universal switching mode power supply with Power Factor Correction providing users with worldwide AC acceptance and low consumption. Powersoft bridgeable switch mode fixed frequency class D patented outputs provide high quality sound, excellent damping factor and cooler circuits for stable performances over time and longer amplifier life. Optional sensing and communication board, on RS485 bus, provides full control and monitoring through proprietary software running on external PC, compatible with all other Powersoft D, Q, QTU and K Series amplifiers. The Powersoft D1502 is CE, UL, CCC and KETI approved. D1502 FEATURES• Powersoft legendary universal switch mode power supply with Power Factor Correction • Fixed frequency switch mode output • Patented output filter with ripple cancellation network • Comprehensive front panel indicators • Neutrik© Combo (XLR+Jack) balanced inputs and Speakon© outputs connectors • Selectable HP, LP, BP filters and gate • Fully protected circuit design with: ¾ AC protection: shut down power supply when AC mains voltage is outside operating range ¾ Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output ¾ DC protection: protects against infrasonic signal at the outputs ¾ VHF protections: protects the loudspeakers against non audible, strong, non musical very high frequency signals ¾ Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits ¾ Thermal protection: when output rails reach 75°C (167°F) amplifier shut down outputs, they will unmute automatically when temperature will reach 65°C (149°F) ¾ Long term limiter: protects the loudspeaker against steady long term rms (non audio) signals reducing maximum output • Temperature controlled continuous variable speed fan, front to back airflow • Recessed stepped attenuators • Detachable AC mains cable with IEC 16A socket • Modular construction • Full three years warranty
