Description
Product descriptionStereo integrated amplifier with built-in D/A converter equipped with advanced digital direct control.In order to reproduce digital sources in high quality, it is equipped with an advanced digital direct function that improves the SN at the actual volume level of around -22dB that is normally listened to.In order to reproduce digital sources in high quality, it is equipped with an advanced digital direct function that improves the SN at the actual volume level of around -22dB that is normally listened to.The active volume by the combination of a variable resistor and a linear amplifier is adopted as a volume controller.The D/A converter section is equipped with Yamahas high bit system (8fsx18bit digital filter, 18bit operation twin D/A converter). The power amplifier section uses Yamahas original HCA circuit.This eliminates discontinuities in stiffness characteristics by converting the input signal into positive and negative hyperbolic characteristics, guaranteeing Class A operation for all power and all loads.In order to prevent deterioration of sound quality due to unnecessary radiation from the digital section, a 2BOX construction is used in which the digital section and preamplifier section are each made independent.The input/reckout is a semiconductor selector that uses FET with low distortion and low leakage specifications, and is switched close to the rear input/output terminal.The power supply section is equipped with a 420VA power transformer in a shielded case and a 27,000?Fx2 large capacity aluminum electrolytic capacitor for audio.It is equipped with a digital input terminal in addition to an analog input terminal for 4 inputs: CD, DAT1, DAT2, and VDP/DBS.Furthermore, DAT1 and DAT2 are equipped with digital record output terminals.Equipped with 3 video inputs.Equipped with 3-band tone control with tone jump, balance control, stereo/mono mode switching, subsonic filter, headphone terminal, accessory terminal, etc.Comes with a remote control that allows you to switch inputs and control volume.?Main specificationsRated output (20Hz to 20kHz) 190W+190W (4?, 0.005%)150W+150W(6?, 0.003%)130W+130W(8?, 0.003%)Dynamic power 600W+600W(1?)500W+500W(2?)240W+240W(6?)Damping factor (1kHz, 8?) 200Input sensitivity/impedance Line In:150mV/47k?Output voltage/impedance Rec Out:150mV/680?Practical SN ratio (Vol -22.5dB, IHF-A) Normal: 116dB (2V input)Digital direct: 128dB (7.5V input)Residual noise (IHF-A) Normal: 23?VDigital direct: 7?VChannel separation (1kHz, Vol -22.5dB)Normal: 80dB (5.1k? termination)Digital direct: 100dBTone control Bass: 20Hz, ±10dB (turnover frequency: 350Hz)Treble: 20kHz, ±10dB (turnover frequency: 3.5kHz)Mid: 1kHz, ±10dB (center frequency: 1kHz)Subsonic filter 15Hz, -6dB/octAudio mute -20dBInput sensitivity/impedance MC:100?V/100?MM:2.5?V/47k?Maximum allowable input (1kHz, 0.01%) MC:6mVMM:140mVSN ratio MC:83dB (250?V, input short)MM:90dB(2.5mV, input short)RIAA deviation MC, MM: ±0.2dBHarmonic distortion rate (20Hz to 20kHz, at 3V output) MC, MM: 0.003%Channel separation (1kHz, input short) MC, MM: 80dBOutput voltage (0dB signal input) Normal, Rec Out output: 2VDigital direct output: 7.5VHarmonic distortion rate (EIAJ) 0.002% or lessDynamic range (EIAJ) 100dB or moreSN ratio (EIAJ) 118dBChannel separation (1kHz) 100dBPower supply voltage AC100V, 50Hz/60HzPower consumption 350WExternal dimensions Width 473x Height 170x Depth 475mmWeight 28kg?The condition of the product is that there are no noticeable scratches or stains.I was able to confirm the power supply.
