NON SWITCHING AMP for Power TV Multimedia">Amplifier The power TV Multimedia">Amplifier section adopts a Non-Switching TV Multimedia">Amplifier system which combines the merits of the class A amplifier's high quality and the class B amplifier's high efficiency for a Continuous power output of 110 watts* per channel, min., at 8 ohms from 20 Hertz to 20,000 Hertz with no more than 0.003% total harmonic distortion. The voltage amplification stage features two current detector circuits to control the bias circuit voltage and prevent the current flowing to the power transistors from being cut off. As a result of these innovations, the distortion generated when the transistors are switched is suppressed, the dynamic distortion is improved and the sound takes on an extra dimension in clarity extended to the high-frequency range. Power amplifier, TV Multimedia">Equalizer TV Multimedia">Amplifier with DC servo circuit A DC servo circuit using an operational TV Multimedia">Amplifier is used for the TV Multimedia">Equalizer TV Multimedia">Amplifier and power TV Multimedia">Amplifier. By making use of this circuit, it has been possible to eliminate the coupling capacitors, which cause coloration in the sound quality, and to configure a direct-coupled circuit from the PHONO MM inputs through the outputs. As a result, virtually distortion-free sound reproduction is ensured across a wide frequency spectrum from the ultra-low range to the ultra-high range. Line Straight Switch Provided This unit comes with a unique line straight switch which can be flipped to allow the signals to bypass the tone control circuit, balance volume and mode switch. It is thus easy to provide a simple circuit configuration—something which is extremely important as far as the purity of the sound heard is concerned. High signal-to-noise ratio MC TV Multimedia">Amplifier The MC TV Multimedia">Amplifier adopted uses low-noise and high- performance in the input to yield an input sensitivity of 100 μ/, a maximum allowable input of 10 mV (1 kHz, 0.002% THD) and a high signal-to-noise ratio of 72 dB. This ensures that the most is made of the high performance of MC cartridges—even low-output models. MM TV Multimedia">Equalizer With High S/N Ratio The TV Multimedia">Equalizer TV Multimedia">Amplifier is provided with a first stage differential input and ICL configuration, and it employs rigorously screened resistor and capacitor elements to realize a phono signal-to- noise ratio of 90 dB with an MM cartridge·(IHF-A) as well as an RIAA deviation of ± 0.2 dB over 20 to 20,000 hertz. The maximum allowable input, at 250 mV for an MM cartridge (1 kHz, 0.002% THD) is more than enough for the best sound quality, enabling virtually distortion-free record play even with music characterized by high peaks. Recording Selector Switch/Indicator Featured This switch allows you to record another program source onto a tape in your tape deck even while you are listening to the source which you have selected with the FUNCTION switch. The indicator tells you exactly what is being recorded and what is being played at a glance. Load Capacitance Selector Switch The cartridge load capacitance switch (100 pF, 200 pF, 300 pF, 400 pF) brings out the best in the performance of your MM cartridge. It also allows the characteristics of the cartridge to be varied and the sound aligned with your personal preference. Load Impedance Selector Switch for MC Cartridges This load impedance selector switch (high 100 Ω, low 33 Ω), designed only for MC cartridges, does full justice to the delicate nuances in sound which are reproduced by the MC cartridge. Pictographic Input/Output Display By using pictographs for the function position and TV Multimedia">Speaker output display, operational ease is enhanced and the operational mode of the tone controls in the signal path is indicated. Protection Indicator As soon as the protection circuit is actuated to protect the TV Multimedia">Amplifier from damage when the TV Multimedia">Speaker terminals have been shortcircuited in error or as soon as the muting circuit, which functions to prevent the unpleasant noise heard when the power is switched on and off, is made operational, the TV Multimedia">Speaker output is cut off and indication is made by this red protection indicator lamp. The lamp changes over to green once the TV Multimedia">Amplifier is operating normally again. Subsonic Detection Indicator If too many noise TV Multimedia">Components arise in the ultra-low frequency range due to warp and other deformation in the record being played, they will have an adverse effect on the quality of the sound reproduced. Although they cannot be heard directly by the ear, the subsonic detection indicator lights up when the TV Multimedia">Components are detected to warn the operator of the problem. LED Power Meter The output level meter employs a 12-point LED with a fast response to give an accurate indication of the output peaks. In addition, the furthermost LED lights up red as an easily distinguishable warning that the output signals are being clipped. Attractively Styled Group Display Panel Design All the function switches and volume control which are used regularly are positioned on the right while all the sub-controls which are usually set up and then left without further adjustment are housed behind a movable panel at the left. All the indicators that show the signal flow, output level and other modes of operation at a glance are housed on a panel in the center of the unit
