Commentary
Pre-main amplifier equipped with D/A converter.
The D/A converter section uses a 4 x oversampling digital filter.
It also supports three different sampling frequencies, and the sampling frequency is changed automatically depending on the source.
The D/A converter block is housed in a shield case together with the circuit board to reduce the adverse effect of digital noise on the analog block.
The power amplifier section is equipped with a dynamic super A circuit that is resistant to the impedance fluctuation and back electromotive force of the speaker.
To prevent the sound quality from being adversely affected by the vibration generated from the power transformer, it is mounted on a plate with a W dimple structure with excellent vibration damping characteristics.
This plate is treated with copper plating to improve vibration control performance.
Equipped with a DAC direct switch that minimizes the routing of the input digital signal and reduces the number of contacts as much as possible.
When the analog source is played back, the digital clock operation is automatically completely stopped to eliminate the influence of digital noise.
It also has a CD direct switch that reduces the distance between analog signal lines and contact points.
Uses a 2-point support system volume with an excellent SN ratio.
Equipped with a sound selector that can select video and audio separately and allow cross-play.
The Route 3 input / output jacks are installed for visual source.
Wireless remote control is included.
