Cinematic Sound

Nothing Could Be Easier to Use or Provide Better Performance

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

Fits Neatly and Easily on Your Rig

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. Beachtek recommends the Redrock Micro DSLR Baseplate.
