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.

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.
