Эквалайзер недорогой серии 20, во
многом идентичной по параметрам
знаменитой серии 30. Новое
семейство эквалайзеров dbx
отличается наличием
регулируемых лимитеров на
каждом канале. Кроме того,
имеется система шумоподавления
на основе динамического фильтра,
существенно снижающая шумы даже
при экстремальных положениях
движков. Симметричные входы и
выходы (XLR, 6.3 мм phono jack и зажимные
винты).
