Product descriptionThe integrated amplifier which adopted the ?-X balance circuit and the NEW diamond differential circuit.*It uses an ?-X balance circuit, and the circuit configuration uses a balanced amplification method that inevitably cancels noise. This differs from normal amplifier circuits in that not only the signal amplification but also the power supply is not referenced to earth.Furthermore, the AU-?607Extra uses a NEW diamond differential circuit and lowers the impedance of the entire circuit to further improve quality.In addition, the speaker drive is not the conventional method of driving between the amplifier output and ground, but a double push-pull method that drives the speaker from both directions, with the + side of the speaker equally as the - side. This corresponds to impedance changes and phase changes.*Uses a NEW diamond differential circuit in which the FETs used in the first stage are connected in cascade.This reduces the influence on sound quality from connected equipment due to differences in output impedance when using power amplifier direct.*The power supply section uses Sansuis proprietary balanced power supply that is independent from the ground and has a closed loop.Since the current is always equal on the + and - sides, the negative effects on the music signal caused by unbalanced power supplies are eliminated.The parts used include a large power transformer and a custom electrolytic capacitor developed for audio use.*The amplifier uses twin monaural construction.This is done by placing the power supply section in the center and symmetrically separating the power amplifier section mounted on a large heat sinker, which provides a sense of stability and eliminates the difference in signal levels between the L/R units. Compatible with crosstalk, power system vibration, and music signal interference.*Equipped with a power amplifier direct switch and two normal input systems.*Uses a unique direct access rotary switch that selects the input source from inside the rear terminal.

Product descriptionAn integrated amplifier created by pouring Sansuis technology into a simple body.*The amplifiers amplification circuit is separated from the ground circuit, and a revolutionary advanced ?-X balance circuit equipped with NM-LAPT is adopted.This circuit transmits and amplifies signals simultaneously, and has a balanced configuration that does not receive external noise or common mode distortion. The push-pull system with four amplifiers on the + and - sides of the output drives the speakers from both + and - sides under the same conditions.In addition, NM-LAPT, developed specifically for audio, lowers the impedance of the circuit and improves dynamic frequency characteristics.*A stable power supply is achieved by using the NEW ?-X balanced power supply with a closed-loop configuration packed with high-quality sound components such as custom-made electrolytic capacitors and power transformers.*Vibrations in the power supply system and signal system are effectively controlled by reinforced twin monaural construction with optimal weight balance, and vibration transmission paths such as between the volume and chassis, where all music signals pass, are Isolated mechanical feedback is introduced, and vibration damping is performed using pure copper isolation parts.*We thoroughly pursue the quality of each part, including the part through which the music signal passes directly, as well as the insulator with vibration dispersion and non-resonance design. *Equipped with a power amplifier direct that allows audio signals to be input directly to the power amplifier section.*By setting the CD player to power amplifier direct, you can back-record CDs and other sources while listening. For example, while playing the source in Normal 1, it is possible to back-record the source such as a CD input in Normal 2.*Equipped with a 6-unit detent volume, gold-plated input terminal, large speaker terminal, and polarity display power cord/AC outlet.?Main specificationsModel integrated amplifierEffective output (10Hz to 20kHz, both channels working simultaneously) 6?: 105W+105W 8?: 90W+90WTotal harmonic distortion rate (at effective output) 0.003% or less (8?)Frequency characteristics (1W) DC ~ 300kHz, +0 -3dBCross modulation distortion rate 0.003% or less (8?)Damping factor 150(8?)Input sensitivity/impedance (1kHz) 1V/5k?SN ratio (A network) 120dB or moreDynamic power 2?:280W 4?:220W 6?:155WTIM distortion (SAWTOOTH) below measurement limit valueSlew rate 180V/?secRise time 0.6?secInput sensitivity/impedance (1kHz) Phono MM: 2.5mV/47k?
