Description
Product descriptionStereo integrated amplifier that uses an ?-X balance circuit.The ?-X balance circuit is a method in which both the + and - sides of the signal are transmitted and amplified using separate dedicated amplifiers, and because they are separated from the ground, they can theoretically suppress the effects of noise and distortion from the ground. Masu.In addition, the power section input stage has a differential balanced input configuration using low-noise FETs, and the common mode rejection ratio (CMRR) on the + and - sides of the signal system is large, so common mode noise and distortion are eliminated. The circuit itself is canceling.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, the transformer is equipped with an ultra-large transformer that has enhanced vibration isolation and heat resistance with high-density filling material.In addition, a custom electrolytic capacitor specifically designed for audio with fast charge/discharge speed and a high current capacity fast recovery diode are used.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 five large insulators (CF5 insulators) with optimal load distribution are used.The volume uses a high-precision 6-unit detent type volume with little sound quality deterioration and small left/right interlocking error, and can be narrowed down to around -90dB, improving the S/N ratio on implementation.The equalizer section for analog discs uses a phono equalizer with a discrete configuration.It is equipped with a tone control with defeat.Equipped with a balanced input and power amplifier direct function that enables highly pure balanced transmission and amplification.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 (20Hz to 20kHz,both channels drive) 190W+190W(6?)160W+160W(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?)Frequency characteristics (1W) DC ~ 300kHz +0 -3dBInput sensitivity/impedance Balance, Normal: 1V/3k?(1kHz)SN ratio (A network) 120dB or moreTIM distortion (SAWTOOTH) below measurement limit valueSlew rate ±200V/?sec(6?)Rise time 0.5?secInput 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(THD 0.01%) MM:250mVMC:25mVFrequency characteristics Phono MM:20Hz~20kHz ±0.2dBCD, Line, Tape/DAT/Play1?2?3:DC~300kHz +0 -3dBSN ratio Phono MM:90dB or morePhono MC:75dB or moreTuner, Line, CD, Tape/DAT/Play1?2?3: 110dB or moreTone control Bass maximum variation: ±5dB (50Hz)Treble maximum change: ±5dB (15kHz)Turnover frequency: 75Hz, 150HzSubsonic filter 16Hz(-3dB), 6dB/octLoudness 50Hz:+6dB10kHz:+4dBRated power consumption 400WExternal dimensions Width 448x Height 160x Depth 441mmWeight 28.0kg?The condition of the product is slightly scratched and dirty.This is an individual with no particular problems.I dont have any records so I cant confirm.If you look closely at the photo, there is some dust.
