Features

The integrated amplifier achieves incredibly clear and dynamic sound quality
The JENO Engine transmits and processes audio signals in full digital with minimal jitter from the input stage to the power stage. The LAPC enables an ideal impulse response for any type of speaker. Moreover, the Advanced Speed Silent Power Supply achieves both high-speed switching and low noise. With these features, the amplifier realizes excellent drive capability and dynamic sound full of energy as well as full digital, clear sound.

Maximally reduces noise and vibrations to achieve dynamic sound reproduction with the build quality appealing to listeners’ sensibilities The interior of this unit is divided into three independent sections by inner chassis to create the power supply section as a source of noises, power amplifier section handling high currents, and terminal section handling fine signals. In addition to this three-section construction that eliminates mutual noise effects, the Double Steel Plate Chassis consists of a high-rigidity inner chassis and the bottom chassis with 2 mm steel plate is provided to maximally reduce noise and vibrations.
The large twin peak power meter on the front panel vividly displays the dynamics of the sound. The volume knob with circular finish uses pure solid aluminum for a superior operational feeling. The excellent build quality appeals to listeners’ sensibilities.

Supports from analog to digital sound sources with various high-quality sound technologies

Compatible with MM/MC cartridge, and equipped with various high-quality sound technologies, such
as low-noise PHONO circuit to realise record reproduction with a better S/N ratio, high-quality ruby mica condenser for USB input, Digital Noise Isolation Architecture with power conditioner by non-magnetism carbon film resistance, and Optimally Activated Circuit System to minimise inner noise by partially stopping unnecessary circuit blocks.

Test tone emitted during measurement To ensure the measurement accuracy, the speakers output a test tone at regular intervals. (For approximately 3 minutes) It is not possible to change the volume of the audio being output while the measurement is in progress.

1. Press [AMP ] to turn this unit on.

2. Press and hold [LAPC] until “Please Wait” is displayed.
   “LAPC Measuring” is displayed and this unit will start measuring the output signal of the amplifier. Check that a test tone is output from both the left and right speakers. When the measurement is complete, amplifier output correction will be automatically turned on.

   • The amplifier signal measurement is cancelled in the following condition.
   • Pressing [MUTE]/[LAPC]
   • Switching the input source
   • I f you connect headphones during amplifier signal measurement or amplifier output correction, it will be cancelled.

Turning on/off the output correction function
