Description
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. The contacts of the rotary switch are gold plated to ensure high quality.* Equipped with a source direct switch, it is possible to play without going through attached circuits such as balanced volume, muting, and subsonic filter.?Main specificationsModel ?-X Balanced Integrated AmplifierEffective output (10Hz to 20kHz, both channels driven) 6?:105W+105W8?: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 1V(Normal)SN ratio (A network) 120dB or moreTIM distortion (SAWTOOTH) below measurement limit valueSlew rate ±180V/?secRise time 0.6?secInput sensitivity/impedance (1kHz) Phono MM:2.5mV/47k?Phono MC:300?V/100?CD, Tuner, Line, Tape Play1?2?3:150mV/20k?Phono maximum allowable input MM(THD 0.01%):210mVMC(THD 0.1%):21mVFrequency characteristics Phono MM: 20Hz to 20000Hz, ±0.2dBCD, Line: DC ~ 300kHz, +0 -3dBTape Play-1, 2, 3: 1Hz ~ 300kHz +0 -3dBSN ratio Phono MM:88dB or morePhono MC:70dB or moreCD, Tuner, Line, Tape Play-1?2?3: 110dB or moreTone control maximum variation BASS: ±6dB (50Hz)TREBLE:±6dB(15kHz)Subsonic filter 16Hz(-3dB), 6dB/octLoudness 50Hz:+8dB10kHz:+6dB Audio muting -20dBRated power consumption (Electrical Appliance and Material Control Law) 250WExternal dimensions Width 430x Height 160x Depth 450mmWeight 18.0kg?The condition of the product is Rank B/There are some signs of use such as scratches and dirt, but it is in good condition for normal use.For remote delivery areas, additional fees will be charged.
