Description
Product descriptionAn integrated amplifier that enhances cost performance while inheriting the technology of A-D5.Direct energy MOS-FET is adopted as the output stage.This element has extremely low on-resistance, which allows it to achieve excellent power linearity and has high low-load drive capability.A wide range linear circuit is adopted as the circuit configuration.This circuit has a simple structure in which the necessary gain is obtained by one-stage amplification using a current feedback circuit, and has excellent current linearity, flat output impedance, and stable drive from low to high frequencies.By combining Direct Energy MOS-FET and wide range linear circuit, source resistance and speaker output terminal choke coils are eliminated, resulting in simplicity, low heat generation, and miniaturization.A complementary capacity pair is adopted as the smoothing capacitor of the power supply section.In this capacitor, the magnetic fields generated on the positive and negative sides cancel each other out.It uses parts that emphasize sound quality, such as non-magnetic resistors and audio capacitors that were originally reserved for high-end models.The internal layout is symmetrical, ensuring the shortest signal path possible.In addition, each Direct Energy MOS-FET uses an independent heat sink made of thick aluminum extrusion, eliminating the need for insulation between the power element and the heat sink, which could not be eliminated with conventional amplifiers. Moreover, mutual interference between direct energy MOS-FETs in the output stage is eliminated.The front panel and aluminum volume knob are made of extruded aluminum.Equipped with a direct button that passes the balance circuit and tone circuit.Equipped with a local circuit off function that cuts off the power to the circuit when not in use.?Main specificationsModel integrated amplifierPractical maximum output 100W+100W (EIAJ, 4?)Rated output (both channels driven) 70W+70W (4?, 20Hz to 20kHz, 0.2%)45W+45W(8?, 20Hz~20kHz, 0.1%)Input sensitivity/impedance Phono MM:2.8mV/50k?CD, Tuner, Line, Tape1/MD, Tape2/monitor:200mV/50k?Phono maximum allowable input Phono MM: 150mV (1kHz, 0.1%)Output level/impedance Tape1/MD, Tape2/Monitor:200mV/1k?Tape rec:200mV/1k?Frequency characteristics Phono MM:20Hz~20kHz ±0.3dBCD, Tuner, Line, Tape1/MD, Tape2/Monitor: 5Hz - 100kHz +0 -2dBTone control Bass:±8dB(100Hz)Treble:±8dB(10kHz)Loudness contour (Vol -30dB) +5dB (100Hz), +3dB (10kHz)S/N ratio(IHF, A network, short circuit) Phono MM:85dB(at 5mV)CD, Tuner, Line, Tape1/MD, Tape2/Monitor: 108dBSpeaker load impedance A, B: 4? to 16?A+B:8??32?AC outlet power switch interlocking: 2 systems (100W)Power switch non-interlocking: 1 system (100W)Power supply voltage AC100V, 50Hz/60HzPower consumption 110W (Electrical Appliance and Material Control Law)External dimensions Width 420x Height 114x Depth 307mmWeight 5.9kg?The condition of the product is that it is a used item, so there may be signs of use or deterioration over time (scratches, dirt, etc.) that do not affect use.The product in the image is a sample image.
