http://rcl-radio.ru/?p=57700
Основные технические характеристики:
Напряжение питания от 8 В (рекомендуемое 8.5 В) до 10 В
Ток потребления от 27 до 47 мА
КНИ не более 0,01 %
Регулировка громкости от -80 до +15 дБ
Регулировка тембра ВЧ, СЧ и НЧ ±15 дБ
Регулировка предусилителя от 0 до +15 дБ
Вход: четыре входа, один из которых квазидифференциальный, три других – одинаковые по параметрам стерео-входы
Выход: 4 линейных канала и 1 сабвуфер (раздельная регулировка громкости каждого выхода)
Тоновая компенсация звука
Переключающиеся частотные полосы регулировки тембра и тонкомпенсации, с изменяемой шириной захвата регулировки.
