Condition: Early models of Earthworks microphones (see Models Affected) and Earthworks model M30 microphone will become unstable and oscillate with transformer-balanced microphone inputs such as Sound Devices MP-1, MP-2 and MixPre.
Rechargeable AA batteries for internal powering of pro audio gear have historically been poor performers. Alkaline primary cells, and more recently Li-ion cells, are usually the preferred cell chemistry. Fortunately, battery chemistries have evolved — in some applications there is actually a runtime advantage when using the newer NiMH rechargeable batteries with portable gear versus […]
Condition Depending on several conditions, chiefly the microphone, the transformer-balanced inputs, such as those on the 302, 442, MixPre, MM-1, MP-1, and MP2, can get into an oscillating condition with a microphone that renders the audio unusable. This oscillation is often described as a “motorboating” condition since this low frequency oscillation sounds like a motor […]
This article moves beyond the basics to specifically discuss metering with Sound Devices 442, MixPre, and MP-2 portable products. A good general understanding of audio level metering is helpful before understanding the nuances of Sound Devices meters.
Sound Devices MixPre, 302, and 442 mixers are designed to link directly with each other using a single cable. The Mix In connection on the 302 and 442 is directly compatible with the Mix Out/Tape Out connections on the MixPre, 302, and 442. When linked, one mixer becomes the master and the other the “auxiliary”.
Lectrosonics wireless systems are popular companions to Sound Devices field mixers. Their construction and audio performance make a “kit” built with Sound Devices mixers and “Lectro” wireless very flexible, compact, and capable.
