BeachTek DXA-MICRO PRO+ Camera Audio Adapter
The BeachTek DXA-MICRO PRO+ brings an XLR microphone, wireless receivers, and camera-mounted mics into a camera’s 3.5 mm mic input through low-noise preamps, and runs on a built-in rechargeable battery.
It has one XLR input with switchable 48 V phantom power, two 3.5 mm mono inputs, and one 3.5 mm stereo input, each mini-jack with plug-in power. Two sources can be recorded at once, and each channel has its own level control. Good/Over indicators show the level at a glance, and a headphone amplifier with volume control feeds a 3.5 mm jack.
Two gain settings send the camera a strong, clean signal, so the camera’s own gain can be turned down to cut hiss. With a single mono mic, audio bracketing records the second channel at a lower level as a safety track.
The built-in 3.7 V, 2400 mAh LiPo battery runs the adapter for up to 10 hours without phantom power and charges in 4 hours over Micro USB. A USB battery pack can also power it from the same port, and a green, yellow, or red light shows the charge.
The adapter mounts under the camera to its tripod attachment, or on the hot shoe with the brass mounting foot, clear of the camera’s battery drawer. A removable cheese plate with a shoe slot and threaded 1/4-inch and 3/8-inch holes holds accessories on top, and a mounting shoe on each side of the extruded aluminum chassis takes a wireless receiver.
