Product Overview


  • High-Quality, Low-Noise Preamp
  • Record Audio to Camera without Syncing
  • Stereo/Mono/Dual-Mono/Audio Bracketing
  • Headphone & Loopback Monitoring on Hand

Designed for cinema cameras, the Beachtek DXA-CINE is an active adapter with built-in preamplifiers that allow you to record high-quality audio directly to camera, no syncing necessary. These preamps provide 60 dB of gain and over 100 dB of dynamic range, as well as low-noise operation. You can use this adapter with cameras such as the RED DSMC2 or ARRI ALEXA Mini, alongside most self-powered filmic microphones, as well as wireless mic receivers.

A plethora of inputs and outputs are provided, including two mono 3.5mm inputs, one stereo 3.5mm input, one 5-pin balanced XLR output, and one unbalanced 3.5mm output. The DXA-CINE’s aforementioned inputs all provide plug-in power, and with multiple outputs on hand, you have options to feed either of the previously mentioned cameras. If your particular camera has a headphone output jack, you can loop it back into the device and monitor sound from that path to make doubly sure what you’re hearing is what you’re getting “on tape.”

While a high/low gain switch lets you dictate a basic starting point for level, the DXA-CINE’s detented trim controls ensure that you always make precise and consistent adjustments; this comes in handy when you need to match audio between takes performed hours or days apart (or on either side of a completely different setup/location—reshoots come to mind). Built-in green/yellow/red indicators give you a quick overview of your levels at any time. Dual-mono and stereo recording are both possible, while bracketing audio is also a cinch. Thus, you can always record a lower-level track when using a mono microphone.

Flexible mounting options abound, including a built-in thumbscrew with a 1/4"-20 mounting bolt and a separate, included brass mounting foot for hot-shoe mounting. Multiple accessories can be attached to the DXA-CINE via three 1/4”-20 threaded inserts as well. For power, a 2-pin LEMO jack is on hand, and configurations are possible for D-tap.
