Beachtek DXA-ALEXA Low-Noise Preamplifier for ARRI ALEXA Mini Camera

Designed primarily for the ALEXA Mini, but compatible with cameras such as the RED DSMC2, the Beachtek DXA-ALEXA is a low-noise preamplifier which connects directly to your camera, capturing audio through its transformer-balanced inputs and obviates the need for external syncing. The preamp itself sports a 100 dB dynamic range, and the construction of its inputs ensure galvanic isolation, as well as high common mode rejection in the face of common obstacles, such as electromagnetic interference.

Beachtek DXA-PRE Two-Channel Preamplifier for Cinema Cameras

Connect professional XLR-equipped microphones or line-level signals to your RED, ALEXA, and other cinema cameras or DSLR/mirrorless camera with the compact, rugged, and easily mountable Beachtek DXA-PRE, a two-channel preamplifier with phantom-powered XLR inputs. Its powerful preamps offer up to 60 dB of gain while delivering low noise and a wide 100 dB dynamic range. Thanks to its integrated shoe mount, the supplied brass mounting foot, and the included V-CLICK quick-release plate, the DXA-PRE accommodates an array of mounting configurations, including rail mounting with an optional third-party accessory.

Each channel features a balanced XLR mic/line input with switchable 48V phantom power for condenser mics, low/high gain settings, and a trim knob. An easy-to-read LED meter helps you keep track of your levels. Select mono or stereo for the output signal.
