Description
Product descriptionAn integrated amplifier created to commemorate the 15th anniversary of the 607 series.?The power stage uses a pair of 2SK405/2SJ115 MOS FETs capable of high-speed amplification, and the advanced ?-X balance circuit brings out the capabilities of the elements to achieve high stability and delicate expressive power. .The advanced ?-X balance circuit has a structure in which dedicated amplifiers are installed on the + and - sides of the output, and the push-pull method uses a total of four amplifiers to drive the speakers from both directions, making the circuit itself immune to external noise. Common mode distortion is canceled. Furthermore, by combining it with a NEW diamond differential circuit that can instantaneously supply large currents, it achieves low impedance, clean, and excellent operating characteristics.?The power supply section uses a newly developed power transformer and electrolytic capacitor, and has a closed-loop configuration in which the power supply section is completely independent and separated from the ground, so that music signals generated from power imbalance etc. Reduces the negative impact on-The chassis uses reinforced twin monaural construction.In this structure, the power supply section consisting of a power transformer and an electrolytic capacitor is placed in the center, and the power units are arranged symmetrically. This achieves an ideal weight balance and effectively prevents sound quality deterioration due to the amplifiers natural vibrations generated from the power supply system and signal system.-Introduced isolated mechanical feedback to analyze and effectively control vibration transmission paths and magnetostriction sources.This method uses a large amount of pure copper isolation parts, which have high internal loss and excellent vibration absorption ability, and is used for power and signal systems such as between the transformer and chassis, the MOS FET mounting area, and the master volume fixing area. Vibration, resonance, and magnetostriction are thoroughly eliminated in all parts including the beginning.?The quality of the parts has been carefully considered, and we have adopted parts that are non-magnetic, vibration-proof, low impedance, and high-speed, such as specially designed power transformers and electrolytic capacitors. . -Equipped with a power amplifier direct function that inputs high-output digital music signals directly to the power amplifier section.Additionally, in order to achieve high-purity transmission and amplification, it is equipped with a balanced input terminal in addition to the normal input terminal.Equipped with source power direct, all line input signals can be transmitted to the power amplifier with one touch without passing through any accessory functions.Equipped with a recording selector function, even if you connect a CD player directly to the power amplifier, you can back-record other sources while listening. For example, while listening to the input source in Normal 1, you can record another source such as a CD in Normal 2.- Equipped with a phono equalizer for MC/MM cartridges.- There are 11 input terminals, all of which use gold-plated terminals.- A 6-unit detent volume is used for the volume, and the volume knob is machined from aluminum.-Equipped with real side wood.?The power cable uses a power cord with polarity indication.- Equipped with an AC outlet.-There were two color variations: gold and black.?Main specificationsModel integrated amplifierEffective output (10Hz to 20kHz,Both channels operate simultaneously) 55W+55W(6?) 45W+45W(8?)Total harmonic distortion rate (at effective output) 0.008% or less (8?)Cross modulation distortion rate 0.008% or less (8?)Damping factor 150(8?)Frequency characteristics (1W) DC ~ 300kHz +0dB, -3dBInput sensitivity/impedance 1V/5k?(1kHz)SN ratio (A network) 120dB or moreDynamic power 70W (6?) 85W (4?) 90W (2?)TIM 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/DAT-1, 2, 3: 150mV/20k?Phono maximum allowable input MM (THD 0.01%): 210mV MC (THD 0.1%): 21mVFrequency characteristics (1W) Phono MM:20Hz~20kHz ±0.2dBCD, Tuner, Line, Tape/DAT-1, 2, 3: DC ~ 200kHz +0dB, -3dBSN ratio (A network) Phono MM:88dB or morePhono MC:70dB or moreCD, Tuner, Line, Tape/DAT-1, 2, 3: 110dB or moreTone control Bass maximum variation: ±6dB (50Hz)Treble maximum change: ±6dB (15kHz)Subsonic filter 16Hz(-3dB), 6dB/octLoudness +4dB(50Hz), +4dB(10kHz)Rated power consumption 160WExternal dimensions Width 460x Height 159x Depth 446mmWeight 18.8kg?The condition of the product is that there are no noticeable scratches or stains.For remote delivery areas, additional fees will be charged.
