## Content

## In Short
- Dirac Live Room Correction is expanding to more Denon AV receivers.
- Newly supported models include AVR-X2900H, AVR-X3900H, AVR-X2900H DAB, and AVC-X3900H.
- The feature is available as a paid upgrade.

## What Happened
Dirac Live Room Correction is now available as an upgrade for additional Denon AV receivers, including the AVR-X2900H and AVR-X3900H series models announced on May 29, 2026.

Dirac Live Room Correction is software that measures how sound behaves in a room and then adjusts the audio output to compensate. In simple terms, it is like tuning your speakers for your living room so dialogue and music sound clearer across different seats.

The company says the tool addresses both magnitude and phase distortions. Magnitude issues are volume and frequency balance problems, like boomy bass or dull vocals. Phase issues are timing misalignments between speakers, which can blur imaging, meaning it becomes harder to pinpoint where sounds are coming from.

Denon’s newly supported receivers target multichannel home audio and video setups. The AVR-X2900H is a 7.2-channel receiver, while the AVR-X3900H supports 11.4-channel processing and includes four independent subwoofer outputs.

Denon also positions the AVR-X3900H as a better match for add-ons like Dirac Live Bass Control and Active Room Treatment. Bass Control focuses on coordinating multiple subwoofers so low frequencies are more even around the room.

## Why It Matters
This update pushes advanced room tuning into more mid-range home theater systems, not just premium models.

For buyers, an “upgrade path” matters because it can extend the usable life of hardware. Instead of replacing an AV receiver to get better calibration, users can add software-based correction after purchase.

For the broader audio market, it signals a continued shift toward paid, software-driven features on consumer electronics. That approach is similar to how apps add functionality over time, except it is happening inside home entertainment hardware.
