Dirac Roadmap for 2022 Denon & Marantz AV Products

https://www.audioholics.com/editorials/dirac-road-map-denon-marantz-2022

TL;DR

1. 2023/03 更新後會支援 Dirac Live room Limited and full bandwidth versions

Dirac Live room Limited USD 259; full bandwidth versions USD 359

* Final pricing is under Dirac’s control and may change in the future.

2. 預計 2024 更新支援 Dirac Live Bass Control - TBD (待確認)

3. Dirac Spatial Correction --> 慢慢等

4. Dirac Live 只支援 2022 年以後發表的 Denon/Marantz 產品 -> >安心升級吧 XD

5. 要額外買 Dirac Live 專用的校正麥克風; 不能使用內附的 Audyssey 麥克風

Sound United recently announced new 2022 AV products for Denon and Marantz

capable of supporting Dirac room correction. Dirac is an industry leading

room correction software that is favored by many home theater enthusiasts and

audiophiles.

There are 3 Types of Dirac Room Correction to consider:

Basic Dirac Live: The original version, its SIMO and has no bass management
of its own

Dirac Live with Bass Control: Dirac Live Bass Control Single Subwoofer
Dirac LIve Bass Control multi Subwoofer

Dirac Spatial Correction (formally called Unison)

This is the version we discussed in our Dirac Spatial Correction Youtube

video and it is not something that exists on any consumer products for the

home. It is used in some cars, like the noted Volvo. This approach is a

fundamentally different approach to room correction, being a MIMO instead of

SIMO approach. Even the multi-sub bass control noted above is a SIMO

approach, it doesn't cancel the models, it is simply exciting modes more

evenly amongst the 2-4 LF sources. The MIMO approach used in this new spatial

room correction has some really cool advantages. When Unison was released, I

had talked to DIRAC and was unclear how it could be utilized in a system like

a Marantz processor and typical off the shelf speakers. They claim to have

worked that out so that is why we are curious if this is in fact going to be

supported in Marantz and Denon products.

Q: What Version(s) of Dirac will Denon & Marantz AV products support?

A. At this point, we can only confirm that we will support both Dirac

Live room correction technology - limited and full bandwidth versions AFTER

the firmware update in March 2023. We also plan to support Bass Control

upgrade although the integration efforts has not yet started. We expect we

should be able to release a new firmware to support Dirac Live Bass Control

upgrade sometime in 2024 - TBD.

Regarding Spatial correction, we will continue to work with Dirac team

for any solutions they would release to consumer AV products in the future,

however, it is just too early to commit anything new at this point.

Q: Will Last Year’s Denon/Marantz products be upgradeable to Dirac?

A: The previous Denon/Marantz models such as the AVR-X8500H, SR7015/8015,

AV7706 or the AV8805 will NOT support Dirac Live upgradability. Our Dirac

Live integration is enabled by adopting new DSP and software for the 2022

new Denon/Marantz lineup ONLY.

Q: Will Dirac be an upcharge or a free firmware update?

A: Dirac live will be an optional upgrade (upcharge). Once after firmware

update in 2023 March, customers, either installers or DIY consumers, will

need to go to dirac.com/denon or dirac.com/marantz to purchase a license key

from Dirac to calibrate each AVR. Customers can purchase either a limited

version or a full band-width. A MAC address will be needed. A license key

for the limited version will cost $259 and the full-bandwidth version will

cost $349. It will be possible to upgrade from the limited to the

full-band width version at later stage with additional cost of $99.

Note: Final pricing is under Dirac’s control and may change in the future.

We recommend to register at the Dirac websites below to be notified when the
service is available.

Q: Can DIRAC be run over Audyssey or are they separate calibrations?

A: Separate calibrations. You can NOT use a part of Audyssey functions such

as Dynamic Volume or Dynamic EQ on Dirac Live, and vice versa. You will also

need a dedicated microphone of your choice to perform Dirac calibration like

a Mini DSP UMIK-1. The included Audyssey microphone in the AVR is for

Audyssey calibration ONLY.

Q: Could one conceivable run DIRAC and Audyssey, store them in different
presets to do A/B comparisons?

A: Yes, each Denon and Marantz AVR supports “Speaker Preset” function where

you can store up to 2 calibration results on the AVR and switch between these

two from the AVR’s “Option” menu. For example:

“Speaker Preset 1” = Audyssey

“Speaker Preset 2” = Dirac Live

The Speaker Preset function was originally developed to allow you to store

two separate speaker configuration and/or Audyssey calibration results

easily on the AVR, without using the Audyssey app or a USB thumb drive to

rewrite the AVR’s setting.

Q: Do Sound United products support manual PEQ or do you have to do those
adjustments in DIRAC or Audyssey?

A: We do not support manual PEQ. Any EQ adjustments have to be done through

the Dirac Live software, or the Audyssey MultEQ app or MultEQ-X software.
