Ну, может вокалисту нужен эффект матюгальника.
Да, нет не нужен.
Усугубим вопрос: есть ли комбинация аппаратуры с "бортовым" питанием от 12В, которая бы могла адекватно звучать в Цветы-ской "Звездочке" и "Колыбельной"?
Что Это будет? Размеры, вес?
======
И вдогонку: а голосовые комбики с бортовым питанием Е?
... и добавил:Посмотрите, что я нарыл из Роландов на иБее: на 8 алкалайновых батарейках тянет 50Вт 4 часа, а 25Вт 10 часов!!!
И при этом 2х20см динамика и 2х5см.
Неужто такой не потянет голос???
