Các bác ơi, cho mình hỏi về con Amp PMA-500 với, con này giá xuất xưởng 75.000 yên năm 1973, mình hỏi định đánh với Onkyo D500II Liverpool, thấy bảo đánh hợp với thằng này, nó có gì đặc biệt không ạ. Bác nào biết về con PMA-500 này chỉ giáo em với, cháu nó đây: Link tham khảo khảo đây: http://translate.google.com/translate?u ... en&ie=UTF8 Rating of type Type All silicon transistor stereo pre- main amplifier <Power> Music output 100W Rated output At the time of one ch drive: 42W×2 (8Ω and THD 0.1%) Both ch drive time: 40W+40W (8Ω and THD 0.5%) 37W+37W (8Ω and THD 0.1%) Harmonic distortion factor 0.03% or less (- at the time of 3dB rated output) Cross modulation distortion factor (60Hz: 7kHz=4: 1) 0.06% or less (- at the time of 3dB rated output) Output bandwidth 5Hz~35kHz +0 -1dB (THD 0.1%) Below ~75kHz 5Hz +0 -3dB (THD 0.5%) Frequency characteristic (output Po=10Wconst.) 10Hz~100kHz +0 -1dB Input impedance 80kΩ±20% (above ~20kHz below 5Hz) Input sensitivity 1Vrms/100kΩ Residual noise Below 0.01μW (input terminal short circuit) SIGNAL-TO-NOISE RATIO ratio Above 95dB Damping factor 50 or more (below ~10kHz 5Hz) Output impedance Below 0.16Ω (at below 1kHz pure resistance) <Pre> Rated output 1.0Vrms Installed capacity 5.0Vrms Harmonic distortion factor Installed capacity time: 0.1% or less (100Hz, 1kHz and 10kHz) At the time of rated output: 0.05% or less (100Hz, 1kHz and 10kHz) Cross modulation distortion factor 0.1% or less (at the time of rated output) Frequency characteristic (Tone defeat) 10Hz~40kHz +0 -1dB Input sensitivity/impedance Phono1, 2: 2mVrms/60kΩ±20% MIC: 1mVrms/100kΩ±20% Tuner and AUX1, 2: 100mVrms/60kΩ±20% Tape PB: 500mVrms/100kΩ±20% Maximum permissible input (THD 1% or less) Phono1, 2: 200mVrms (1kHz) MIC L/R: 80mVrms RIAA deviation 30Hz~15kHz ±0.5dB SIGNAL-TO-NOISE RATIO ratio (input terminal short circuit) Phono1, 2: Above 65dB MIC: Above 55dB Tuner and AUX1, 2, Tape: Above 75dB Audio muting 0, - 10dB, - 20dB Tone control Bass: +10dB~-10.5dB (80Hz) Treble: +10dB~-9dB (12kHz) High Filter 9kHz and 12dB/oct Low Filter 40Hz and 12dB/oct Output level/impedance Tape rec (DIN): Below 100mVrms/1kΩ (40mVrms/80kΩ) <Synthesis> Use semiconductor Transistor: 39 FET: 2 Diode: 10 Barrister: 2 AC outlet switched: 2 systems, 250W unswitched: 1 systems, 150W Power supply voltage AC100V/120V/200V/220V/240V and 50Hz/60Hz Electric power consumption (electric supplies control method) 56W External size Width 430× height 140× depth 350mm Weight 12.5kg Giá 2M có được không các bác, các bác chỉ dẫn giúp nhé để thứ 2 này mình còn liệu, thanks
