Тема: TDA7719
ИМС TDA7719 представляет собой Hi-Fi аудиопроцессор с программируемой матрицей входов, имеет 6 аудио выходов, независимый аттенюатор для каждого выхода и входа, три полосы регулировки тембра с изменяемой центральной частотой и добротностью, полосовой фильтр для сабвуферов (два выхода) с фазоинвертором, тонкомпенсация. При подачи на вход стерео сигнала аудиопроцессор после обработки преобразует его в квадро и дополнительные два канала для сабвуферов.
