Adastra

Adastra is yet another heritage brand, established all the way back in 1949 and still powering forward today in the commercial installation audio market and several other sectors which include systems for the hard of hearing, conference audio and ceiling speaker systems for both public buildings and private homes.

Found in airports, stadiums, schools and university buildings, Adastra installation speakers are designed to be functional and discreet, blending into the environment for a seamless appearance, yet powerful and purposeful in use, be that for simple background music or for emergency announcements.

Adastra - Heard but not seen

As is often the way with purposeful products, they do their work in near secret, installed to be out of sight and not bring attention to themselves. A great deal of Adastra's range falls into this unique category for audio, where performance and reliability far outweigh any need for glamorous design to help sell it. That's not to say style isn't an important factor though, as the ability to blend and vanish into surroundings is a big part of commercial audio.

From its fully-featured 100V line amplifiers and speaker systems to its emergency warning horns and tannoys, Adastra has something suitable for all locations and environments that require distributed audio.

Adastra - Technology

At the core of Adastra's products is their ease of use. They have been specifically designed to be extremely easy for both installer and the end-user to be comfortable with the minimum amount of time.

This may sound simple, but with the multitude of features on offer, especially in a larger installation system, the routing and control of zones can often be quite complex and is a testament to Adastra's product development that they have made their amplifiers and speakers so approachable in both fitment and operation.

Adastra products include design features such as (depending on model)

  • 100V line operation
  • Low impedance capable
  • IP weather rating
  • White ABS resin enclosures
  • Bluetooth wireless streaming
  • Multi-zone output
  • USB / SD card media playback

Adastra - Commercial

For professional site installations, the Adastra range of ceiling speakers and wall mount speakers are a perfect choice, available in standard indoor and IP weather-rated outdoor formats, these no-nonsense high-quality speaker systems are designed to perform. Coupled with one of the fantastic RM series 100V line amplifiers which give all the modern features of USB playback and Bluetooth, they offer the user a simple to use system.

Adastra - Consumer

Waterproof speakers allow the system to extend into outside areas, be it the patio, garden terrace or a designated smoking area, creating cohesion throughout the building. With the latest trend being on clean uncluttered homes and offices, restaurants and social spaces, the Adastra range gives an easy to use and affordable way to have distributed audio in ceilings and other discreet locations, blending in with the aesthetic seamlessly, which is a big departure from the imposing hi-fi stacks and large speakers that once took centre stage. With wireless streaming from Bluetooth devices, you have instant and full control over what you hear, in any room. Explore the variety of Adastra speakers and other related products today.
