The Beachtek DXA Micro Pro, from a US-based company specializing in audio recording for cameras, features excellent preamps, low noise, gain control, and 48V phantom power. Inputs include either two 3.5mm analog microphones or one 3.5mm and one XLR. It's a rare item, not sold in Japan. It's fully functional and being sold because of a change in camera system. While there are some minor scratches, it doesn't affect its operation. It can be mounted on a camera's hot shoe. It also has a 1/4-20 thread on top, allowing it to be mounted below the camera. It runs on a 9V battery. Two rechargeable batteries are included. (Unfortunately, the charger is missing and will not be included.)
