About the REL HT-Air™ MkII

The HT-Air MKII represents a significant leap forward in REL's commitment to combining peak performance with unparalleled ease of use in subwoofer technology. This advanced system not only underscores REL's dedication to the highest standards of craftsmanship but also showcases their innovative approach to wireless audio transmission. With the HT-Air MKII, users can experience audio at 5.8 GHz, transmitting music or film soundtracks without the compromise of digital compression, thus ensuring the most dynamic and high-quality sound possible.

Key Features of HT-Air MKII:

  • Plug-and-Play Convenience: Setting up the HT-Air MKII is remarkably straightforward. Within moments of connecting the transmitter and receiver, users can begin transmitting audio seamlessly, making it an ideal solution for both music and film enthusiasts.
  • Uncompressed Audio Transmission: Operating at 5.8 GHz, the HT-Air MKII transmits audio without digital compression. This choice preserves the original sound quality, offering listeners the purest and most dynamic audio experience.
  • Versatile Connectivity: The system is adept at handling both Low Level (RCA-RCA) and LFE/.1 (single RCA) transmissions, catering to a broad range of audio setups and preferences.

Craftsmanship and Design:

REL doesn't just create subwoofers; they craft experiences. The HT-Air MKII is encased in a cast acrylic case that is as durable as it is aesthetically pleasing. The weight of the unit is a testament to its quality, designed to complement the heft of high-quality interconnect cables without becoming cumbersome. Finished with five coats of hand-applied acrylic lacquer, the HT-Air MKII's glossy black appearance is as meticulously considered as its internal engineering.

Effortless REL Pairing:

REL has simplified the wireless pairing process to a mere button press, eliminating the complexities often associated with setting up wireless systems. The HT-Air MKII comes pre-programmed and ready to connect, using a dedicated protocol that bypasses the complications of conventional Wi-Fi, ensuring a hassle-free setup right out of the box.

The Freedom of Wireless:

Employing a 3rd generation 5.8 GHz chip, the HT-Air MKII is REL's most advanced wireless solution to date. Capable of streaming high-fidelity audio over distances of at least 40 feet (12 meters) and potentially further under ideal conditions, it offers a freedom of placement and convenience that wired systems cannot match. With a lightning-fast response time of around 17 ms, the HT-Air MKII promises a listening experience that rivals, and in some aspects surpasses, that of wired connections.

In summary, the HT-Air MKII is not just a step forward for REL in terms of technology and performance; it is a leap towards redefining what users can expect from wireless audio. With its combination of ease of use, aesthetic appeal, and cutting-edge technology, the HT-Air MKII invites users to experience the pure, unadulterated joy of high-quality sound.
