Description
Product descriptionStereo integrated amplifier that uses an ?-X balance circuit.?The ?-X balance circuit uses separate dedicated amplifiers for both the + and - sides of the signal to transmit and amplify it, and since it is separated from the ground, it is theoretically possible to avoid noise and distortion from the ground. prevents the effects ofIn addition, the power section input stage is a differentially balanced input using low-noise FETs, and the common mode rejection ratio (CMRR) on the + side and - side of the signal system is large, so common mode noise and distortion are eliminated from the circuit. itself has been cancelled.Furthermore, whereas conventional amplifiers drive between the amplifier output and ground, the ?-X balance circuit drives from both the + side and the - side, so power supply noise is not mixed in, and the output from the speakers is reduced. This prevents IHM (Interface Hum Modulation) from occurring due to back electromotive force.-The power supply section uses a unique balanced power supply that is independent from the ground and has a closed loop.The current is always equal on the + and - sides, which prevents the signal from being adversely affected by unbalanced power supplies, and is designed to be resistant to noise from the AC line and fluctuations in the power supply.In addition, it is equipped with a large-capacity transformer with excellent regulation, as well as a gold supply capacitor and fast recovery diode with fast charging and discharging speed.- In addition to the master regulator, a twin regulator system is used with a local regulator placed on the phono equalizer board and preamplifier board.Since it is a two-stage regulator, it is resistant to power fluctuations and load fluctuations, making it possible to provide a stable and clean power supply.- Equipped with an active tone control that can also be defeated.?The power section board uses a discrete board with excellent vibration damping properties.-The chassis uses a solid and anti-flux chassis designed to eliminate vibration and noise interference. Each stage is completely separated and shielded by a separator, and external vibrations are also prevented by five large insulators (CF5 insulators) with optimal load distribution.-Uses a phono equalizer with FET configuration.-Equipped with a source direct function that connects all input sources directly to the predrive stage, bypassing the subsonic filter, muting, and balance control accessory circuits.?Main specificationsModel ?-X Balanced Integrated AmplifierRated output(10Hz to 20kHz, both channels driven) 105W+105W(6?) 90W+90W(8?)Total harmonic distortion rate (at effective output) 0.003% or less (8?)Cross modulation distortion rate (at effective output) 0.003% or less (8?)Damping factor 150(8?)TIM distortion (SAWTOOTH) below measurement limit valueInput sensitivity/impedance(1kHz) Phono MM:2.5mV/47k?Phono MC:300?V/100?CD, Tuner, Line, Processor, Tape/DAT/Play1?2?3:150mV/47k?Phono maximum allowable input MM:210mV(THD 0.01%)MC:21mV(THD 0.1%)Frequency characteristics Phono MM:20Hz-20kHz ±0.2dBCD, Line, Tape/DAT/Play1?2?3:1Hz~300kHz +0 -3dBSN ratio Phono MM:88dB or morePhono MC:70dB or moreTuner, Line, CD, Tape/DAT/Play1?2?3: 110dB or moreTone control Bass maximum variation: ±5dB (50Hz)Treble maximum change: ±5dB (15kHz)Subsonic filter 16Hz(-3dB), 6dB/octLoudness 50Hz:+8dB10kHz:+6dBAudio muting -20dBRated power consumption 240WExternal dimensions Width 448x Height 160x Depth 441mmWeight 16.0kg?The condition of the product is slightly scratched and dirty.There is no volume noise, and the sound is still good.I have connected the tone control, speaker AB select, various input terminals, etc. to the best of my ability, and they are working without any problems. (There will be a slight rasping sound at the moment of switching the switch)I couldnt check the PHONO terminal because I didnt have a record player.For remote delivery areas, additional fees will be charged.
