First, based on an amplifier circuit with excellent bare characteristics, TIM distortion is reduced by applying an appropriate amount of NFB, contributing to the reproduction of sound quality and atmosphere in the mid-high range. And in the DC servo, the problem of intermodulation distortion and DC drift caused by harmful ultra-low frequency components is solved, and at the same time, an excellent speaker braking effect is obtained.High-gain-ization of the equalizer is realized by the duo beta circuit, and not only the MM cartridge but also the MC cartridge can be directly connected to the equalizer.The circuit consists of a cascode differential input first-stage circuit with a bootstrap by low-noise FET and an output stage of class-A single-ended push-pull circuit adoption, and has excellent nakedness characteristics.Furthermore, since the gain of the equalizer itself is high, we have also succeeded in banishing the flat amplifier that causes sound quality deterioration.(Although the input sensitivity of the MC input terminal is 0.3mV and most MC cartridges can be connected, it is recommended to use a high impedance type as much as possible.) The output stage has a high ft (high cutoff frequency). , Cob (collector output capacity) and low large-sized power transistors are carefully selected and used, the speed of the driver circuit is also increased, and the switching distortion is banished.In addition, a newly developed loop-type heat pipe is used to enhance the heat dissipation effect.The line straight composition is adopted and faithful transmission is enabled by setting it as the composition which directly connected the MC equalizer part and the power amplifier part.LUX scheme NF type tone control is adopted as tone control.The turnover frequency can also be switched in two steps for each of high and low frequencies, and a complete bypass is also possible if the defeat position is used.The 10 element right-and-left independent type indicator which displays a peak power in real time is carried.The watt display which can read an output directly is adopted, and it is also possible to turn off with a switch when unnecessary.Two tapes monitors, a dubbing switch, a subsonic filter, and a high cut filter are carried.Model ratingModel integrated amplifierContinuous effective output 70W+70W (8, both channel operation, 20Hz-20kHz)Total harmonic distortion 0.03% (8, 70W, 20Hz-20kHz)intermodulation distortion 0.03% (8, 70W, 60Hz:7kHz=4:1)Frequency characteristic Phono MM, MC: 20Hz - 20kHz ±0.3dBTuner, AUX: 10Hz - 100kHz -1dBInput sensitivity/impedance Phono MM: 1.2mV/50kPhono MC: 0.3mV/100Tuner, AUX: 190mV/50kSN ratio (IHF-A) Phono man-month: 77dBPhono MC: 71dBTuner, AUX: 105dBsubsonic filter 15Hz, 30Hzhigh cut filter 9kHz, 15kHzAC outlet switched: 2 systemsunswitched: 1 systempower consumption 250WExternal dimensions Width 466x height 145x depth 333mmweight 12kg

Huollettu elokuussa 2023.100V laite ja muuntaja mukaan.CommentaryA stereo pre-main amplifier developed by inheriting the design philosophy of SA-9900.Like SA-9900, it adopts a side terminal system in which input / output terminals are arranged on the left and right panels.As a result, the input terminal is completely integrated with the equalizer board to prevent degradation of the high-frequency characteristics caused by the shielding wire.The power amplifier section uses a pure complimentary service OCL circuit directly connected to all stages. It consists of a single stage differential with ± 2 power supplies and a parallel push-pull configuration.By making the load of the pre-driver constant current, the bare gain is increased, and by applying the optimum NFB, the distortion is reduced over a wide band. By using the power supply before the output stage as a stabilizing power supply, the transient crossover distortion at minute outputs is eliminated. By using the parallel push-pull output stage, the linearity of current characteristics is improved and distortion is reduced.In addition, a differential amplifier and a bias compensation circuit are adopted to improve stability, so that fluctuation of offset voltage due to external temperature change is minimized.The equalizer is equipped with a differential amplifier using a low-noise transistor can-shielded at the first stage to stabilize the output mid-point and improve the SN ratio. In addition, 100% DC NFB is applied to reduce distortion and improve stability.In addition, the final stage SEPP operates in class A operation until large amplitude, enabling high output voltage to be extracted at a low distortion rate.In addition, carefully selected high-precision elements are used to improve sound quality.There are two Phono inputs, one of which is capable of level adjustment up to -12dB and 4-point switching of input impedance.For level adjustment, NFB changes up to -6dB, and output volume changes from -6dB to -12dB.The tone circuit is a 2-stage direct-coupled circuit. By using FET in the first stage, noise variation due to volume position is minimized. In addition, NFB is applied to the 2-stage direct-coupled circuit in both AC and DC, and is sent to the tone circuit in the next stage with low impedance, making it an ideal condition for tone circuit operation.In addition, the voltage at the midpoint is stabilized by two power supply systems, plus and minus 24 v (total 48 v).The volume uses a full-scale attenuator type volume with 22 contacts, and the use of high-precision printing resistors reduces gang errors.It also has a 3-step lever type attenuator.NFB type tone control is adopted, and 3-step turnover frequency switching is adopted to expand the control range.It is also equipped with a tone on/off switch.It is equipped with a duplicate switch that can dub tapes 1 to 2 and 2 to 1.The power supply section is equipped with two large electrolytic capacitors of 18,000 F.Equipped with low filter / high filter.A protective circuit with a built-in relay is mounted to suppress noise when power is turned on/off.The actual measurement data of each product is attached.Model RatingType Stereo pre-main amplifierPower Amplifier UnitCircuit system Differential 1-stage all stages directly connected parallel PP pure complimentary service OCLEffective output (both channels driven, 20 Hz to 20 kHz) 100W + 100W (4 )80W + 80W (8 )Harmonic distortion factor (20 Hz to 20 kHz) 0.1% or Less (Effective Output)0.05% or Less (8 at 40W Output)0.05% or Less (8 at 1W output)Cross modulation distortion factor 0.1% or Less (Effective Output)0.05% or Less (8 at 40W Output)0.05% or Less (8 at 1W output)Output Bandwidth (IHF, both channel drives) 5 Hz ~ 40 kHz (Distortion Factor 0.1%)Frequency characteristic 10 Hz to 80 kHz + 0 -1dBInput Sensitivity / Impedance Power amp in : 1V/50k Output terminal Speaker A / B : 4 ~ 16 Speaker A + B : 8 ~ 16 Headphone : 4 ~ 16 Damping factor (20 Hz to 20 kHz) 30 or moreS/N 100 dB or more (IHF, A-network, short circuit)Preamplifier SectionCircuit system Equalizer amplifier : A class SEPP with 2 positive and negative power supplies, one stage differential and three stage direct connectionControl amplifier : Positive and negative 2 power supply, first stage FETInput Sensitivity / Impedance Phono1 : 2.5mV/50k Phono2 : 2.5 to 10mV/35k , 50k , 70k , 100k Tuner, Aux1, 2, Tape PB1, 2 : 150mV/50k Phono maximum allowable input(Harmonic distortion rate 0.1%, 1 kHz) Phono1:250mVPhono2 : 250 mV to 500 mVOutput Level / Impedance Tape Rec1, 2 : 150 mvPre-out : 2V/1k Harmonic distortion factor (20 Hz to 20 kHz) Not more than 0.05%Frequency characteristic Phono (RIAA deviation) : 30 Hz to 15 kHz ± 0.2 dBTuner, Aux, Tape PB : 7 7 hz to 40 khz + 0 to 1 dbTone control Bass: ± 10 dB (25Hz/50Hz/100Hz)Turnover Frequency : 100Hz/200Hz/400HzTreble: ± 10 db (8kHz/16kHz/32kHz)Turnover Frequency : 2kHz/4kHz/8kHzFilter Low : 15 Hz, 30 Hz, 12dB/oct.High : 8 kHz, 12 kHz, 12dB/oct.Muting 0, -15dB, -30dBS/N (IHF, A-networkShort circuit) Phono : 70 dB or moreTuner, Aux, Tape PB : 90 dB or higherSemiconductor used Transistor : 54FET : 2Diode, etc. : 26 pcsAC outlet Power switch interlock : 2 systemsPower switch not linked : 1 systemPower supply voltage 100 VAC, 50Hz/60HzPower consumption 190W (rated)530W maximumExternal dimensions Width 420x Height 165x Depth 403 mmWeight 17.2kg
