Description
Product descriptionThe integrated amplifier is equipped with a Dual Amp Class A with ZDR circuit that is a combination of a pure class A amplifier and a high power class AB amplifier (bootstrap amplifier). The slight distortion component generated at the output stage is also canceled by the ZDR circuit.Equipped with Yamahas original RICHNESS circuit.NS-2000 exclusive, NS-1000x/NS-1000M, and general-purpose 3 positions reinforce the low frequency f characteristic with the most audibly natural 1-octave width.For the capacitor in the power supply part, we have adopted an audio chemical condenser with a multi-divided foil multi-terminal structure from the standpoint of emphasizing sound quality. The current amplification stage has one channel of 55000?Fx2, and the voltage amplification stage has one channel of 4700?Fx2, with a total capacity of approximately 240,000?F.Furthermore, by using separate transformers for the preamplifier and power amplifier sections, stable power supply is possible even when there are dynamic load fluctuations.Furthermore, by using a non-current earth + one-point earth that does not supply power to the earth, modulation and fluctuations in the output signal are eliminated and amplification stability is maintained.For the volume, we use a precision 4-channel volume that narrows down before and after the flat amplifier, improving the actual S/N and suppressing noise even at low volumes.We have thoroughly improved the sound quality by introducing quality parts such as a copper-plated chassis, oxygen-free copper wire, and gold-plated pin jack terminals.The exterior features a solid aluminum machined volume knob, a knob inside the ceiling panel, and poly-coated real walnut side panels.?Main specificationsModel integrated amplifierRated output (20Hz to 20kHz) 150W+150W (6?, distortion 0.003%)130W+130W (8?, distortion 0.003%)Power band width 10Hz to 100000Hz (65W, 8?, distortion 0.02%)Damping factor 200 or more (1kHz, 8?)Input sensitivity/impedance Phono1 MC:100?V/100?, 1k?Phono1 MM:2.5mV/47k?(220pF, 330pF)100?Phono2 MM:2.5mV/47k? 220pFAUX:150mV/47k?Main In:1V/100k?Total harmonic distortion MC:0.004%AUX:0.003%Main In:0.002%RIAA deviation MM, MC: 20Hz to 20000Hz, ±0.2dBS/N ratio (IHF-A) MC:83dBMM:88dBRichness 1:+7.5dB, 30Hz2:+7.5dB, 40Hz3:+7.5dB, 50HzPower supply AC100V, 50/60HzPower consumption 420WExternal dimensions Width 473x Height 169x Depth 464mmWeight 26kg?The condition of the product is that it is a used product with no noticeable scratches.
