Sister companies Denon and Marantz have become the first A/V receiver manufacturers to release firmware updates enabling their products to decode DTS:X soundtracks. The free firmware upgrade is currently available on the companies’ flagship units: Denon’s AVR-X7200W/WA receiver and Marantz’s AV8802A preamp/processor. Owners of those models can download the firmware immediately, directly from the respective units.

Owners of other “DTS:X-ready” models will be happy to know that this initial upgrade list is about to get longer.

On February 18, Denon will release the DTS:X firmware update for its AVR-X6200W and AVR-X4200W receivers. And on March 3, Marantz plans to release DTS:X firmware updates for its SR7010 and SR6010 A/V receivers, and its AV7702mkII preamp/processor.  Denon and Marantz have created special pages to help users prepare for the firmware upgrade at and

When will other companies release DTS:X updates?

Denon and Marantz are first out of the gate with DTS:X upgrades on select models, but neither company has announced firmware updates for the rest of their DTS:X-ready lineup. None of the other manufacturers with DTS:X-ready receivers on the market have announced firmware updates either.

Sources tell me Yamaha plans to provide its first DTS:X firmware upgrade as early as March. The timeframe for other manufacturers—including Anthem, Onkyo, Integra, Theta Digital, Steinway Lyngdorf—is even more vague. Barring surprise announcements, users might have to wait until late spring or early summer to get the firmware updates that will enable them to play DTS:X soundtracks in their home theaters.

What more have we learned about DTS:X?

As firmware upgrades for Denon and Marantz slowly trickle out, we’ve learned a bit more about how the technology’s potential and real-world implementation are coming together. I recently sat down with DTS’s Director of Global Communication Jordan Miller and gained some additional insight about the technology.

With regard to how DTS:X supports multiple speaker layouts, Miller said: “In its current state, DTS:X itself supports nearly any layout you can imagine. Practically speaking, there is a limitation to how many layouts each manufacturer would like to support, so it’s a case-by-case basis.” For those A/V receivers that have been sold as “DTS:X ready,” you’ll see traditional 5.x, 7.x, or 9.x layouts, plus two or four height speakers. 11.2. is the maximum DTS:X configuration that A/V receivers will support for the immediate future.

In practice, users have multiple options for height speakers. You can use in-ceiling, on-wall, and even Dolby Atmos up-firing speakers for height channels. Miller told me that if up-firing speakers are used, “DTS:X outputs audio as if there were physical height speakers present.” Height speakers can only be configured in pairs.
