По каким параметрам можно понять, раскачает ли карта микрофон или нет? Так же напишите пожалуйста в каких характеристиках уступает младшая модель. Мне нужно только записывать голос в микрофон shure sm7b и выводить звук на мониторы adam серии ax . Эти две карты смогут раскачать наушники с сопротивлением 250 Ом?
