Equipped with STMicroelectronics' TDA7498E chip, high power MAX 160W + 160W
By providing a gain setting DIP switch on the back of the unit, the gain setting can be easily changed.
The coupling-less design using a DC servo circuit achieves a faithful and straightforward sound quality.
By incorporating a speaker protection circuit, the speaker is protected from accidental DC leakage.
AC adapter required (sold separately) DC 19-32V/2A DC jack 5.5mm x 2.5mm (center positive)
[Product Features]
■High power (160W)
The high-power digital amplifier IC "TDA7498E" enables a maximum output of 160W + 160W.
■ Capacitor-free design using active DC servo circuit
The active DC servo circuit eliminates the need for input couplings.
By eliminating the influence of coupling capacitors in the audio signal line on sound quality changes, it achieves a purer, more direct sound quality that is closer to the original sound.
Furthermore, after generating the positive and negative power supplies, a power regulator stabilizes both the positive and negative power supplies, minimizing the noise floor.
■A small, high-current inductor specifically designed for digital amplifiers.
A small, high-current-capable magnetically shielded inductor is in the output filter section of the main amplifier IC, which is positioned later in the circuit.
This inductor has a significantly smaller volume compared to conventional products, but because it uses flat copper wire, it can handle high currents.
Because it has a larger surface area, the line impedance can be kept low, making it an inductor designed for audio applications.
This significantly improved sound distortion, resulting in a noticeable improvement in sound quality, not only in the numerical values measured by audio analyzers but also in the audible sense.
■ Our commitment to key film capacitors
Similarly, for the film capacitors, which also significantly affect sound quality, we've capacitors that have a solid reputation for audio applications.
All of these are from manufacturers and series models that are highly regarded for Hi-Fi audio.
Even within the same series from the same manufacturer, the sound quality can vary between current models. We take these factors into consideration when making our selections, utilizing vintage (NOS) items as well.
■ Equipped with speaker protection circuit
The coupling capacitor-less design means there is no capacitor to protect against DC leakage, but a protection circuit is included to protect the speaker from any accidental DC leakage.
