Product Features:
■ High Power (160W)
High power digital amplifier IC "TDA7498E" provides a maximum output of 160W + 160W.
- Coupling capacitorless design with active DC servo circuit.
Active DC servo circuitry allows input couplingless
Eliminates the influence of sound change caused by coupling condensers on the audio signal line, resulting in a pure, straighter sound quality that is close to the original sound.
In addition, after generating positive and negative power supply, the power regulator stabilizes both of ± power supplies, and the noise floor is extremely attenuated.
■ Adopts a small and high current compatible inductor for digital amplifiers.
The output filter on the main amplifier IC side of the rear stage uses a magnetic inductor that supports small and high current.
This inductor has a much smaller volume compared to those used in conventional products, but it uses flat wire type copper wire, so it can handle large currents.
The inductor is designed for audio applications with reduced line impedance for less surface area.
This greatly improves the distortion of the sound and the values measured by audio analyzers, but it has achieved a high sound quality that you can see on your hearing.
■Dedicated to major film capacitors
The film capacitors have a major impact on sound quality as well as adopting a highly popular capacitor for audio.
All are adopted by highly rated manufacturers and series model numbers for Hi-Fi audio.
Some of the same manufacturer have changed the sound quality of the current product, and we have selected them totally using vintage (NOS) products, including those around them.
- Speaker protection circuit included
The coupling condenserless design ensures that there is no condenser to protect in the event of a DC leak, but the built-in circuit protects the speaker from accidental DC leaks.
