9i-908 2X250W Dual-channel power amplifier
The 9i-908 2X250W power amplifier is a music amplifier designed by cen.grand. The sound style is a smooth and gentle type, which is good at expressing the emotions of music, and has enough dynamic and driving force.
The 9i-908 is designed for high bias current class AB. The transformer uses a Plitron ring transformer from Canada. The voltage regulation is less than 3% at full load. The filter capacitor uses Nichicon's flagship capacitor “Super through”, which is one of the world's top audio capacitors. The coupling capacitor is US RELCAP. The fine-grained devices lay the foundation for performance, and the outstanding design achieves outstanding performance.
The circuit of the post-stage power amplifier is fully symmetrical, and the front stage is a differential amplifying circuit with a constant current source. The circuits are all traditional designs and have been greatly optimized in power supply design. The volume is controlled to the HiFi class PGA2310.
The design of the power amplifier is different from other audio equipment. The adjustment process is more important than the test process, which determines the connotation of the amplifier. After two years of careful debugging, the 9i-908 is a musical amplifier with outstanding music.
The structure of the 9i-908 is 450mm wide, 460mm deep, 160mm high and 28Kg.
The 9i series of amplifiers have passed the national 3C compulsory certification.
