Designed primarily for the ALEXA Mini, but compatible with cameras such as the RED DSMC2, the Beachtek DXA-ALEXA is a low-noise preamplifier which connects directly to your camera, capturing audio through its transformer-balanced inputs and obviates the need for external syncing. The preamp itself sports a 100 dB dynamic range, and the construction of its inputs ensure galvanic isolation, as well as high common mode rejection in the face of common obstacles, such as electromagnetic interference.

The DXA-ALEXA provides dual gain controls which are detented for precise settings, as well as high/low switches for microphone matching, switchable 48V phantom power for condenser mics, and easy-to-read LED level indicators which give you a good picture of your overall sound; green signifies a level between -40 and +16 dBu, yellow takes you all the way to +4, and red gives you an indication of overs.

A carbon fiber chassis is relatively lightweight at under a pound, while weather-resistant top-panel switches ensure reliability in wide variety of conditions. For outputs, the DXA-ALEXA gives you a balanced 5-pin XLR output that can connect directly to 5-pin LEMO inputs. You can also route signal to other recorders by means of an unbalanced 3.5mm jack. Connections are provided for headphone and loopback monitoring as well. The preamp itself draws power from your existing rig by means of a 2-pin LEMO connection. Thanks to the preamp’s three threaded 1/4"-20 holes, you can mount this unit on the rails of third-party brackets, though a bracket has been included for mounting to camera cages, such as the ARRI ALEXA Mini camera cage.

      Good mounts but needs a quality improvement with the padding adhesive
      Color: White, Size: 1.37" without hook, Color: White, Size: 1.37" without hook
      Needs stronger padding. Falling off the next day. Press on, but comes off again. I should not have to apply my own glue, but it's likely what will be needed.

      Desk Space Saver—Highly Recommend
      Color: White, Size: 1.37" without hook
      This under-desk laptop mount is exactly what I needed to declutter my workspace. I used to leave my laptop on the desk or shuffle it around, but now it’s neatly tucked away and easily accessible. Installation was simple—just a few screws and it was ready to go. The mount holds my 14" laptop securely, and the padding inside prevents scratches. I love that I can slide it in and out without hassle, and it frees up valuable desk space for my monitor and documents. If you're looking to streamline your setup, this is a smart and affordable upgrade.

      Solid Floating Shelves 🛠️🏠
      Color: Black, Number Of Shelves: 4, Size: 15.7in
      I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

      Good looking shelves and easy install - skip the included drywall anchors
      Color: Black, Number Of Shelves: 2, Size: 22in
      I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
