Developed with input from the industry's top audio engineers, Sound Devices 442 encompasses the audio performance, feature set, and mechanical construction demanded by those who rely on audio gear for their livelihood. The 442 contains four microphone preamplifiers that re-define portable audio performance. With its comprehensive inputs and extensive outputs, including direct outputs per channel, the 442 is at home in small run-and-gun applications as well as large, multiple-input productions.
