Description
Product descriptionA preamplifier born from uncompromising traditional craftsmanship.The speaker connection terminal on the rear panel provides a 12W+12W output, and when used in conjunction with the input selector switch, it is also possible to drive an Xtend speaker system.In addition, the headphone terminal on the front can be driven by dynamic type or condenser type, and is equipped with a dedicated volume.FETs are used for all input selector switches.The FET is turned on and off with a minute DC voltage, suppressing switching element noise without affecting frequency characteristics.Equipped with a 5-band program equalizer defeat switch.Adjustment of ±12dB is possible around each frequency of 30Hz, 150Hz, 500Hz, 1500Hz, and 10000Hz.Equipped with independent playback-only and recording-only selector switches, it is also possible to record FM broadcasts while playing records, and to monitor each independently.Equipped with a logarithm expander circuit, the dynamic range is expanded and corrected logarithmically, and at the same time, noises such as hum, hiss, and scratches are reduced.Functions are displayed using red LEDs, and the operating status of each push button switch on the front panel is displayed.The power sensitive outlet circuit (adopts SCR) automatically turns on the preamplifier when the player operates. Also, when the player is turned off, the power is also turned off. amplifierIt is also possible to turn off this feature.The power transformer is triple-shielded with a copper plate, a silicon steel plate, and a metal case to eliminate hum and improve the signal-to-noise ratio.The 24V output voltage is rectified and supplied to the monitor amplifier.In addition, 18V is divided from the output voltage and supplied to the constant voltage circuit and OP amplifier circuit through the IC voltage control circuit.The Phono equalizer amplifier uses four low-impedance, low-noise transistors.In order to demonstrate this low noise effect, a 68? feedback circuit is adopted.The loudness circuit, equalizer, and bandpass filter are all composed of ion-coupled electrolytic differential amplifiers (OP amplifiers).Equipped with a special relay to eliminate transient phenomena caused by turning the power switch ON/OFF.This relay is operated by a transistor switch and sends the output of the preamplifier to the output terminal.A transistor switch incorporates a capacitor with a long time constant and a capacitor with a short time constant.The former capacitor turns on the signal approximately 2 seconds after the power is turned on, and the latter capacitor turns the signal on shortly before the power is turned off. The relay is controlled so that the signal turns OFF.?Main specificationsModel stereo preamplifierFrequency characteristics 20Hz~20kHz +0 -0.5dB10Hz to 100kHz +0 -0.5dB (when equalizer OFF)Distortion rate 0.05% or less (20Hz to 20kHz, at rated output)Input sensitivity/impedance Phono1, 2:2mV/47k?(65pF)AUX, Tuner, Tape 1, 2, 3: 250mV/50k?Hum and noise AUX, Tuner, Tape 1, 2, 3: IHF 100dB, 90dB (no auditory correction)Phono1, 2: IHF 90dB, 80dB (no hearing correction)Output level/impedance Main output: 2.5V/5k?
