Product Description

Get Your Mix On with Sound Devices’ MixPre-D

Need a compact, high-performance portable audio mixer that can handle your most demanding field mixing assignments? The Sound Devices MixPre-D gives you flexible pro connectivity and great-sounding audio capture in a small, lightweight package. MixPre-D sports two studio-grade mic/line inputs with limiters, highpass filters and switchable phantom power, while a variety of analog and digital outputs covers the gamut of currently popular destination cameras and devices. With its robust feature set and digital capabilities, Sound Devices’ MixPre-D will make your life on location a little easier – and give you better audio.

Sound Devices knows what professional production mixers require in a field mixer, and has equipped the MixPre-D accordingly. Production sound can be unruly, and the MixPre-D’s “unclippable” input peak limiters ensure usable sound under the most adverse conditions. The Mid-Side mic technique is widely used in broadcast TV and radio production, and the MixPre-D’s onboard MS matrix lets you record in stereo with the flexibility of changing the stereo perspective later on. Small but important details such as a slate microphone and tone oscillator mark the MixPre-D as a serious tool for professionals. If you’re a pro production mixer, you need one.
