Описание товара
Подробности
Компактный усилители мощности, разработанные для установки в стойки и кафедры. Они отвечают требованиям ENERGY STAR® и относятся к энергетически эффективным усилителям класса D, разработанные с использованием запатентованной технологии CDRS™ - технологии подавления пульсаций от Extron, которая сокращает излучение электромагнитных помех и не мешает работе беспроводного аудио/видео оборудования. Усилители мощности профессионального уровня имеют соотношение сигнал-шум более чем 100 дБ, ( невзвешенный) и коэффициент гармоник (THD) + помехи менее 0.05%. Он имеет систему конвекционного охлаждения и может работать в окружении с недостаточной вентиляцией или ее отсутствием.
- Мощность 200 Вт RMS для акустических систем 70 или 100 Вольт модели
- Суммирующий вход
- Фильтр ВЧ
