Тест ЦАП на алиасинг

Данный тест показывает подавление зеркальных помех на разных типах сигнала: импульсном, многотональном и шумовом.

В большинстве случаев визуальная АЧХ для всех типов сигнала одинакова, но содержит разную подробность по частоте и вертикали.

У некоторых современных ЦАП подавление алиасинга зависит от типа сигнала и получается разная АЧХ для разных сигналов. Это может указывать на более сложный алгоритм обработки цифрового фильтра ЦАП.

We open our presence in social networks

The life of the RAA project is not limited only by measurements. To inform about different events, we open our presence in social networks, where you can be informed of all our news. For example, you can see photos from the High End 2017 Munich in facebook and vk.com photo albums.

It was an interesting exhibition, where we communicated with a large number of manufactures. A lot of manufacturers expressed a desire to cooperate with us. And send products to our test lab for technical measurements. Some products were received immediately at the exhibition. Their measurements already made and add in our database: Shanling M2s, Enigma Acoustics & Lotoo Dharma D200 and Lotoo PAW Pico.

Be with us and follow the news and tests.
