Description
Product descriptionThis integrated amplifier is the highest grade model of Sansuis PB series and is an upgraded version of the AU-777D.Aiming for more faithful sound reproduction, it was developed through extensive hearing tests.The main amplifier section employs a two-stage differential amplification circuit and a complete direct connection system with two plus and minus power supplies without an output capacitor. This makes the NFB uniform from the ultra-high range to the ultra-low range, improving various characteristics.The equalizer stage employs a 3-stage E-E NF type PNP silicon transistor with little noise, and has obtained low noise, low distortion, wide dynamic range, and high stability.A direct connection circuit is used as much as possible for the amplifier circuit, Mylar capacitors are used as much as possible for the necessary parts of the coupling capacitors, and electrolytic capacitors with large phase distortion in the high region and poor transmission characteristics are banished.The tone control section uses Sansuis original triple tone control, which allows adjustment of not only Bass and Treble but also Midrange.The tone selector allows defeat and rise/fall points to be switched to 2 frequencies, and a click step type with 2dB low/treble and 1dB midrange steps for accurate adjustment is adopted.The pre-main section can be separated and used alone.Two tape decks can be used simultaneously and a TapetoTape reprint switch is installed.Also equipped with a stereo balance check circuit, level adjuster, NF type low/high filter, tuner selector, microphone input jack, muting switch, program indicator, headphone jack, DIN connector, etc.Wood case was sold separately.?Main specificationsModel Integrated Amplifier Headphone AmplifierEffective output 70W/70W(4?)80W/80W(8?)Music power (IHF) 180W (4?)140W(8?)Total harmonic distortion rate 0.4%Cross modulation distortion rate 0.4%Power band width (IHF) 10Hz to 30kHzFrequency characteristics 5Hz~100kHzStereo separation 50dBHum and noise 100dBInput sensitivity/impedance 1V/40k?Load impedance 4? to 16?Damping factor 45(8?)Rated output 1VTotal harmonic distortion rate 0.1%Frequency characteristics 15Hz to 70kHzHum and noise (IHF) Phono1, 2:80dBMic:80dBTuner, Aux:85dBInput sensitivity Phono1, 2:2mVMic:3mVTuner, Aux, Tape mon(Pin/Din):200mVRecording output Tape rec(Pin):200mVTape rec(Din):30mVTone control Bass:+12dB~-8dB(20Hz)Midrange: ±5dB (1kHz, 2kHz)Treble:+12dB~-8dB(20kHz)Tone selector Bass: Defeat, 200Hz, 400HzMidrange: Defeat, 1kHz, 2kHzTreble: Defeat, 6kHz, 3kHzLow filter -20dB(20Hz)High filter -18dB(20kHz)Muting -20dBPower consumption 370WExternal dimensions Width 461.5x Height 155x Depth 316mmWeight 17.5kg?The condition of the product is B RANK, used for daily use and has some scratches and stains.For remote delivery areas, additional fees will be chargeThese charges are normally collected by the delivering freight(shipping) company or when you pick the item up. -do not confuse them for additional shipping charges.
