Абонентский громкоговоритель "Обь" с 1957 года выпускал Новосибирский завод низковольтной аппаратуры. АГ "Обь" предназначен для приёма местной радиопрограммы, передаваемой по радиотрансляционной сети с напряжением 30 В. Сопротивление на входе АГ - 4100 Ом. Потребляемая мощность 55 мВт. Диапазон воспроизводимых звуковых частот - 150...5000 Гц. Неравномерность АЧХ - 12 %. Среднее звуковое давление - 1,8 Бар. Выставка проходила с 24 декабря 2021 по 15 марта 2022 года павильон «Рабочий и колхозница» на ВДНХ в Москве. На выставке были представлены редкие документы, которые долгие годы были скрыты под грифом «совершенно секретно», приборы и инструменты учёных 1940-х годов, уникальные фотографии, личные вещи Курчатова и его коллег. Это экспонаты из коллекции Политехнического музея и собрания НИЦ «Курчатовский институт». |
