Beachtek DXA-ALEXA

Low Noise Preamplifier for ARRI ALEXA MINI

Transform your ALEXA Mini to a fully featured mini doc camera with on-board audio capabilities with the Beachtek DXA-ALEXA. The carbon fiber chassis matches the look and feel of the camera and with a weight of under 1 lb, the slim line design will easily fit on your rig and not bog you down. Constructed of top quality components, including weather resistant top panel switches for outstanding reliability and durability.

Also ideal for use with any other mini cinema cameras such as the RED DSMC2 models.

Cinematic Sound

The ultra low-noise preamplifiers provide exceptional performance with over 100dB in dynamic range. The two XLR inputs are transformer balanced for galvanic isolation and high common mode rejection.

The DXA-ALEXA also provides all the features you need including dual gain controls, phantom power, level indicators and headphone monitoring. The tri-color LED level indicators make it a snap in setting the proper recording levels.

The output is a balanced 5-pin XLR that connects directly to the 5-pin Lemo input on the camera via an optional cable. There is also an auxiliary mic level output via an unbalanced stereo mini-jack so it can be connected to a variety of other cameras and recording gear.

Power is from your rig via the 2 pin Lemo connector.

Flexible Mounting Options

With the included bracket, you can mount the DXA-ALEXA in several ways to the camera cage.  When using the ARRI ALEXA Mini camera cage, you can mount it under the handle, side bracket or anywhere with an optional V-Lock. The bracket has captive thumb screws to easily add or remove the device from the camera. The base of the unit has three threaded 1/4″/20 holes to also allow it to be mounted to the rails via a third party rail bracket.
