REL HT-Air MKII Wireless Transmitter

Design takes on new meaning when it transforms everyday items into something extraordinary. This is exactly what the HT-Air MKII achieves with its weighty, cubed wireless design—a reinterpretation of REL’s world-class design language, now made accessible for everyday users. Housed in a cast acrylic case, its quality is evident from the very first touch. This weight isn’t just for show; REL understands that many users will pair the HT-Air MKII with premium interconnects, which can be quite substantial in themselves. As audio enthusiasts, REL have added the extra mass to ensure that using a wireless system never results in irritation or imbalance. It’s just one more sign that REL truly understands the needs of their audience. To complete the look, the HT-Air MKII is finished with five coats of hand-applied acrylic lacquer. That deep, glossy black finish? It’s no accident—quality is simply in REL’s DNA.

The HT-Air MKII is compatible with the HT series subwoofers, which includes the HT/1510, HT/1205 MkII and the HT/1003 MkII.

Prepare to Fall in Love with REL Pairing

REL have long prided themselves on creating some of the simplest, most user-friendly wireless systems in the industry, and the HT-Air MKII is no exception. Pairing is effortless: just press a button on the transmitter—once it begins blinking, press the corresponding button on the receiver. That’s all there is to it. There’s no need to worry about software setup or conventional Wi-Fi issues. REL’s own dedicated wireless protocol means it simply works, right out of the box. Because when you bring something new and exciting home, you want it to function straight away—no fuss, no delay.

Wireless Is Freedom

The HT-Air MKII uses REL’s third-generation 5.8 GHz chip, their most advanced single-chip solution yet. It’s engineered for real-time, continuous streaming of both music and film audio. Whether you’re using left-right stereo inputs or a single .1/LFE input, the HT-Air MKII effortlessly transmits deep, dynamic sub-bass across distances of at least 40 feet (12 metres), and often further in ideal conditions. Matching the performance of REL’s more premium models, it delivers an ultra-fast response time of approximately 17 milliseconds. This speed results in superior sound quality, greater dynamics, and performance that closely rivals that of traditional high-end cabling—freeing you from wires without compromising on performance.
