Description
Product descriptionAn integrated amplifier that is a high-power model of the SQ505X.The main amplifier section employs an all-stage direct connection circuit from which the output capacitor is removed using a ±2 power supply. Moreover, the pure complementary system which combined the power transistor of a PNP/NPN type is adopted as the output stage, and the crossover distortion is removed.The front stage consists of a two-stage differential amplification circuit to ensure stable operation.The equalizer stage of the preamplifier section employs a new three-stage direct connection circuit composed of PNP-NPN-PNP type transistors with high power utilization. Furthermore, an emitter follower circuit is provided behind this stage to keep the input impedance of the Aux terminal high.In addition, as a noise countermeasure, carefully selected ultra-low noise transistors are used in all stages of the preamplifier section to reduce noise. And a tantalum type or mylar type with low leakage current is used for the coupling capacitor between stages to suppress shock noise at the time of switching.The input impedance of the Phono1 terminal can be changed to 3 levels.In addition, the Aux terminal is equipped with a level set.Equipped with a low booster, high/low filter, and attenuator that enhances the bass range.The tone control has a curved point switch.?Main specificationsContinuous output 50W+50W (8?, when both channels are operating)60W/60W (8?, when operating one channel)Total harmonic distortion rate 0.04% or less (8?, 50W)Cross-modulation distortion rate 0.04% or less (8?, 50W, 70:7kHz=4:1)Output bandwidth 5Hz~50kHz -3dB(0.04%)Frequency characteristics 10Hz to 60kHz (within -1dB)Input sensitivity 580mV (8?, 50W)Input impedance 50k?Damping factor 40(8?)80(16?)Residual noise 1mV or lessFrequency characteristics 10Hz~50kHz -3dB(Aux1)Total harmonic distortion rate 0.05% or less (1kHz, 1V, Aux1)Input sensitivity Phono1, 2:2mVAux1: 90mV or more (adjustable)Aux2, 3:80mVInput impedance Phono1: 30k?, 50k?, 100k?Phono2: 50k?Aux1:50k?Aux2, 3: 200k?SN ratio Phono1, 2:63dB or moreAux1, 2, 3: 80dB or moreMaximum allowable input (1kHz) Phono:300mVTone control LUX method NF type with curved point switchingLow frequency curvature point: defeat, 150Hz, 300Hz, 600HzHigh frequency curvature point: defeat, 6kHz, 3kHz, 1.5kHzResidual noise 25?V or lessCrosstalk (1kHz) Phono: -60dB or lessAux: -65dB or lessFilter low cut: 70Hz (-6dB/oct)High cut: 6kHz (-6dB/oct)Low booster 100Hz(6dB/oct)Power consumption 200W (at maximum output, 8? simultaneous load)External dimensions Width 450x Height 160x Depth 268mmWeight 11kg?The condition of the product is that it has signs of use such as scratches and dirt, but is in good condition for normal use.Contractor maintenance completed (signal line connector correction, switch/volume contact correction, power lamp replacement, etc.)For remote delivery areas, additional fees will be charged.
