D – One fainarudyibaisu is switching speed fast for 3 MOS – FET parallel powered, high output and heavy sound and style. D – Four fainarudyibaisu is a sound quality that is currently on, and bipolar transistors to 3P Plug A push-pull class AB is adopted to deliver natural sound possible. D – One/D – The combination of both models in both, four power section suittingudyibaisu Power for 2 MOS – FET parallel for larger toroidarutoransu, high capacity electrolytic capacitor and allows for a powerful source of the structure. Equipped with a convenient built-in crossover. High Pass Filter setting for 15 ~ kHz/Low Pass and high pass or low pass range of 40 ~ kHz (band pass), and D – Four has 2-way multi system, and much more. D – One is in the range of 10 ~ 250hz band pass to the setting. Furthermore, the low range increased to bass boost function (45Hz/0 〜+ 12dB) for over years. Fits all model, high input to connect the speaker output of your original deck, supports. Equipped with newly developed Adep circuit, you can light load safeguards to prevent your error detection when the factory head unit. The connection, no extra hassle of the dummy resistance significantly afterwards. Provides thermal protection, over load, short circuit, etc. The in case of abnormal, haisupi-dopurotekusyon function.
