Sound Devices MixPre-D Compact Field Mixer
The MixPre-D Compact Field Mixer from Sound Devices is a versatile audio mixer built for the digital age. Based on the popular MixPre, the "D" in the name indicates the extensive digital technology that's been incorporated into the mixer. The MixPre-D features a pair of studio-grade mic/line XLR inputs with limiters, high-pass filters, and phantom power. The inputs can be linked in standard or MS mode for stereo recordings. These options are configured via easy-to-use front panel controls.
The MixPre-D puts a heavy emphasis on output, due to the increasing number of cameras and devices being used in professional productions. It offers a pair of mic/line XLR outputs, one of which can also be switched to AES digital output. There is a TA3 consumer mic level output, ideal for DSLR-type inputs, plus a 3.5mm aux output and a 1/4" headphone jack for monitoring. A 24-bit class-compliant USB streaming output is also offered, providing internet connection with Mac, Windows, Linux, and select iOS devices, plus computer audio in the MixPre-D headphones.
Other features of the MixPre-D include a sunlight viewable 16-segment GaN LED output meter with adjustable brightness, and a slate microphone and tone oscillator for labeling takes. The mixer can operate on a pair of AA batteries, or via 5-18VDC power from an external input. The extruded aluminum chassis provides excellent strength and durability while keeping weight down for portability.
