Tổng quan

  • The electrostatic method is a playback method which involves the installation of drive electrodes on either side of a high-polymer film diaphragm with a thickness of only a few microns into each of which a plus signal and a minus signal are fed. This means that XLR connection with a pure balance output CD player makes it possible to listen to the original sound permitted by the balance system without a conversion circuit.
  • The output stage has been incorporated by newly developing a non-feedback (NON-NFB) large current emitter follower Class A amplification circuit. This makes it possible to achieve a much more vivid and dynamic sound quality.
  • The emitter follower at the output stage makes it possible to achieve lower impedance. A major expansion in dynamic range in the upper frequency has also been achieved.
  • DC amplifier configuration without the use of a coupling condenser.
  • A high sound quality, low noise FET is used at the input stage with a simple two-stage amplifying circuit. A natural and pure sound quality with high information quantity is realized.
  • When connecting your favorite attenuator or pre-amplifier, a direct switch that avoids duplication of the volume unit is included.
  • Careful selection of parts with high consideration on sound quality, performance, and the environment.
  • In order to avoid magnetic distortion, the chassis is made of aluminum materials, thereby contributing to purity of sound.
  • Amplification is set at a low level, thereby facilitating subtle adjustment of volume during XLR input and when using high-output CD players, etc.
  • Parallel output terminals (RCA) are included to enable the signal to pass through.
  • A new panel face has been designed with rounded corners and a silver brushed finish.
  • Earspeakers of PRO bias (5-pin) type can be used.
  • Control functions are restricted to the volume, and the input uses a single selecting system between RCA or XLR. This is a drive unit for exclusive use with earspeakers with emphasis placed first and foremost upon purity.
