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. The DXA-ALEXA provides dual gain controls which are detented for precise settings, as well as high/low switches for microphone matching, switchable 48V phantom power for condenser mics, and easy-to-read LED level indicators which give you a good picture of your overall sound; green signifies a level between -40 and +16 dBu, yellow takes you all the way to +4, and red gives you an indication of overs.

A carbon fiber chassis is relatively lightweight at under a pound, while weather-resistant top-panel switches ensure reliability in wide variety of conditions. For outputs, the DXA-ALEXA gives you a balanced 5-pin XLR output that can connect directly to 5-pin LEMO inputs. You can also route signal to other recorders by means of an unbalanced 3.5mm jack. Connections are provided for headphone and loopback monitoring as well. The preamp itself draws power from your existing rig by means of a 2-pin LEMO connection. Thanks to the preamp’s three threaded 1/4"-20 holes, you can mount this unit on the rails of third-party brackets, though a bracket has been included for mounting to camera cages, such as the ARRI ALEXA Mini camera cage.
