Detail Nakamichi M7 Power Amplifier Multiple Channel M-7
Features: 1) This machine is a high-fidelity amplifier designed for 7.1 home theater 2) The circuit adopts analog AB type circuit, and the maximum power amplifier efficiency is 78.5%. 3) 7 channels output, using the ring transformer, made from high purity oxygen free copper enameled wire winding, improve the conversion rate of amplifying circuit, the distortion of power resistance constant reduced the power supply, so that the horn of the constant damping coefficient, make the borne power amplifier more resilient to the load changes, and different speaker with different caliber and brand can handle with ease and excellent performance 4) Effectively avoid the phenomenon of power grab between channels when the signal is large dynamic input 5) It has functions of output overheat, over current, midpoint voltage offset, switching machine protection against shock, soft start protection circuit of power supply, and protect power amplifier and speaker effectively 6) With function of stand-by and soft switch. 7) Power filter uses audio dedicated large capacity electrolytic capacitor to achieve smaller power distortion and lower internal resistance. 8) Pure copper high-grade terminal is adopted for output wiring to minimize wiring resistance and ensure sound quality and non-destructive butt joint. The input stage adopts differential balanced input to effectively reduce the common mode noise caused by connecting wires 9) Low distortion, high SNR, high separation design standard 10) Rated power of each channel 250W RMS @ 8 OHM, maximum rated power of whole machine 1300W
