Pro Audio for your DSLR or Mirrorless Camera
Our most powerful adapter ever!
The BeachTek DXA-SLR ULTRA bridges the gap between DSLR and professional video cameras by enabling professional audio features that facilitate high-quality audio recording directly to the camera. Superb operation and ease of use to make capturing pro audio a snap. Since the audio is recorded directly the camera it will always in sync with the video, eliminating the need for any post production processing. The DXA-SLR ULTRA is the missing link for anyone serious about capturing high-quality audio.
Easily Connect Professional Audio Sources
Attach virtually any audio gear including wireless systems, mixers, sound boards and professional dynamic and condenser microphones
Connect any two audio sources for two channel recording. A typical setup for weddings is a shotgun mic on one channel to capture ambient audio and a wireless on the other to clearly capture the vows. A shotgun mic and/or handheld dynamic mic are often used for ENG work and documentaries. For music videos, you can even take a direct feed from the sound board to capture every note. Each channel can easily be independently adjusted for the optimum recording level – even while recording. The DXA-SLR ULTRA gives you the ability to connect whatever microphones work best for your situation.
Powerful low-noise preamplifiers with dual gain settings provide a strong, clear signal to the camera. This allows you to dramatically reduce the camera gain which effectively replaces the relatively noisy camera preamplifiers with the much cleaner preamplifiers in the adapter for hiss free audio. This is the key to dramatically increasing the signal-to-noise ratio while still being able to record audio directly to the camera. This eliminates having to use a separate digital audio recorder to capture quality audio. The inputs are transformer balanced which provide unrivaled common-mode noise rejection.
The DXA-SLR ULTRA gives you all the features you need for connecting, controlling and monitoring the audio
Combo XLR / ¼” inputs provide maximum flexibility for connecting audio sources. Phantom power is available for each channel and is switchable between power saving 12 volts or full 48 volts. The inputs are transformer balanced for isolation and enhanced circuit protection. Transformers provide galvanic isolation from the driving signal, meaning there is no direct electrical connection to the sensitive input stage of the preamplifier. This protects against ground loops and damage resulting from connection to external faulty equipment. Built-in VU meters make it easy to verify the proper input levels at a glance, while the level controls allow you to adjust the output signal for optimum recording. Built-in fast acting limiters prevent distortion from overly hot inputs for worry free operation. The phone jack lets you monitor the audio from the adapter during recording, or camera during playback. You can also loop the output audio from your camera back into the adapter to monitor confidence sound.
Super Easy to Setup and Use
Nothing could be easier to use or provide better performance
Real switches and volume knobs mean no hunting through multi-layer menus trying to find or change settings. Since the audio is recorded directly to the camera, it will always be in sync with the video which eliminates the need for syncing in post. Everything about the adapter was designed to be extremely easy to use, from the ergonomic all metal chassis with nice rubber grips, to the bright easy to read VU meter and drift free volume controls.
Neutrik brand XLR connectors, recessed switches, rock solid electronics and isolating transformers make this super reliable and dependable. All wrapped up in a sturdy die cast aluminum chassis with nice rubber grips for easy hand holding. The adapter mounts neatly to the bottom of the camera and can also be mounted to any standard tripod.
Add Accessories to Your Camera
A unique feature of the DXA-SLR ULTRA is the sleek detachable BRM-1 rod support system to easily attach a matte box, follow focus, top handle and other gear for incredible versatility. Includes two 3″ rods that are threaded on both ends. Extra rods can be simply threaded on to extend to any length needed.
