Описание
2-канальный усилитель мощности. Серия DD+ разработана для самых требовательных пользователей,основана на схематехнике усилителей класса D с запатентованным модулятором. Преимуществами этой технологии являются низкое выделение тепла, компактный размер и бескомпромиссный звук. Отраженная энергия от громкоговорителя как активной нагрузки перерабатывается блоком питания. Потребление энергии из сети переменного тока снижается, в то время как больше энергии отдается громкоговорителю.
