1:The DRV6805 voltage amplifier module adopts a single-pole lead-lag feedback topology that delivers minimal transient distortion. Equipped with high-precision constant-current biasing, the DRV6805 operates stably across an ultra-wide voltage range from ±5V to ±60V with exceptional working stability.
Simply connect a Darlington current stage to the DRV6805 to build a complete power amplifier. It integrates multiple strengths including optimized circuit topology, discrete-integrated hybrid design, high precision and outstanding reliability.
2:It adopts Motorola ON Semiconductor MJE15030/15031 driver transistors, the universal choice for high-end power amplifiers worldwide, delivering outstanding performance.
For power transistors, it features NJW21193/21194 paired power transistors, renowned globally for ultra-low distortion.These power transistors achieve a distortion figure as low as 0.8% without any feedback control, boasting exceptional performance.With a power handling capacity of 200W, they deliver robust driving force.Most notably, they produce refined, spacious and natural sound quality.
3:The M9300SE is equipped with a powerful power system that effortlessly drives all types of loudspeakers.
Premium components are adopted for the power supply section: it features a massive 220V–230V toroidal transformer.The rectifier is a 25A square bridge rectifier mounted on the base plate for auxiliary heat dissipation.For filtering, two gold-labeled Musecon audio-grade electrolytic capacitors are deployed, each boasting a high capacitance of 15,000 microfarads.
Musecon professional audio filter capacitors are audiophile-grade components built with unique cotton pulp electrolytic paper, delivering mellow, transparent sound.
Separate dedicated windings supply power to the preamplifier, digital circuits and protection circuits of the M9300.Full isolation between all circuit sections eliminates mutual electromagnetic interference.
4:The M9300SE utilizes TI (BB)’s premium digital volume control chip PGA2311 for volume adjustment.Outperforming the classic CS3310, this chip delivers a 120dB dynamic range and ultra-low distortion of only 0.0002%, fully meeting Hi-End audio standards.
Four compact relays are adopted for the M9300SE’s 4-channel input selection, minimizing signal loss and enabling signal transmission via the shortest signal path. 5: It packs all premium design concepts and high-grade components into a compact chassis.Adopting a neat dual-mono structure, the toroidal transformer is kept far away from the input circuits.This design delivers not only superior technical specifications but also unexpectedly stunning sound quality and powerful driving performance.
