Description
Product descriptionAn improved model of AU-?607NRA. *In order to eliminate interference between the power supply windings that occur within the transformer, an EI core transformer dedicated to the speaker drive is installed in the final stage in an independent left and right power supply system, and a toroidal transformer is installed in the power supply of the pre-drive stage. The circuit configuration is such that the power supply to the final stage is made independent.In addition, a ripple filter circuit is adopted for the power supply in the pre-drive stage, making it a more stable power supply.The toroidal transformer is completely shielded with pure copper material, Teflon sheet, and special rubber, and is attached to the back of the front panel in a floating state.*Uses Sansuis original Ultimate ?-X balance circuit.By doubling the current margin of the driver stage compared to conventional models and achieving A-class operation, we have achieved an excellent operating environment in the transmission and amplification process from the input to the output of the first stage, driver stage, and final stage.In addition, a balanced amplifier has a balanced configuration in which all stages do not depend on the ground circuit, and dedicated amplifiers are placed on both sides of the L/R +-, and the push-pull method uses a total of 4 amplifiers to drive the speakers under the same conditions. Unlike conventional ground amplifiers, the sound quality is not impaired by hum or noise components flowing through the ground, and the distortion mechanism caused by the speaker drive is removed, improving sound quality.*The pre-drive stage is equipped with a NEW diamond differential circuit that can output +- without phase inversion.As a result, it has excellent responsiveness to input signals that change momentarily, can supply a stable large current, and suppresses the occurrence of TIM distortion to a very low level.*NM-LAPT (Nonmagnetic Linear Amplification Power Transistor) is used as the power device.*Twin monaural construction is used, with the transformer and electrolytic capacitor placed in the center of the chassis, and the L/R power units arranged symmetrically.This prevents L/R interference and structurally controls vibrations generated in the power supply system and vibration system.*2 Adopts a NEW ?-X balanced power supply that is further advanced with a transformer power supply circuit.The final stage is a left and right independent balanced closed type, the predrive stage is a vertically symmetrical balanced type low current power supply, and the power supply for the predrive stage and final stage is completely separated from the transformer to form a completely independent closed loop configuration.Furthermore, the electrolytic capacitor in the power supply section for the final stage uses an original block capacitor that includes a separator and plain foil in addition to low-magnification sound quality foil.*Reinforced twin monaural construction and isolated mechanical feedback. A mechanical floating system is used for the power transformer.The transformer is installed in a state where it flows from the chassis, structurally blocking interference with sound quality due to vibrations in the power supply system.*A new shape heatsink is used to suppress vibration and resonance of the heatsink to which the power transistor is attached.*Uses an oval insulator made of special materials and structure.*The volume uses a 6-unit detent volume.*Uses a power cord with polarity display.?Main specificationsModel integrated amplifierEffective output (10Hz to 20kHz,Both channels operate simultaneously) 100W+100W (6?)80W+80W(8?)Total harmonic distortion rate (at effective output) 0.003% or less (8?)Cross modulation distortion rate 0.003% or less (8?)Damping factor 150(8?)Frequency characteristics (1W) DC~300kHz+0 -3dBInput sensitivity/impedance 1V/10k?(1kHz)SN ratio (A network) 120dB or moreDynamic power 310W(2?) 210W(4?) 150W(6?)TIM distortion (SAWTOOTH) below measurement limit valueSlew rate 150V/?secRise time 0.6?secInput sensitivity/impedance (1kHz) Phono MM: 2.5mV/47k?

Depending on how you press the speaker changeover switch, sound may come out, but we cannot determine the cause.The color of the top plate is uneven.The rubber part was removed due to deterioration of the feet. Since the plastic surface is exposed, there is a risk of scratches where it is placed.A power cable is not included, so please check for scratches on the knobs.This is a junk item that cannot be returned or exchanged.For remote delivery areas, additional fees will be charged. Import duties,taxes and charges are not included in the item price or shipping charges. These charges are the buyers responsibility. These 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.
