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 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. An optional BT_PWR cable is available to connect the 2-pin LEMO power jack to a D-TAP.

Audio Bracketing

Setup a Second Channel for Backup

A very useful feature allows you to use audio bracketing when using a single mono microphone to have a backup channel that is recorded at a lower level. This gives you a safety track in case the primary channel gets distorted from an overly hot input. This effectively eliminates the need for any limiters which can add their own type of distortion.

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 – we recommend the Redrock Micro DSLR Baseplate.
