Denon Firmware Upgrade for AVR-5308CI and AVP-A1HDCI

Denon Firmware Upgrade for AVR-5308CI and AVP-A1HDCI

Denon Electronics, a premier manufacturer of high-quality home entertainment components, will offer owners of its flagship AVR-5308CI A/V Receiver and AVP-A1HDCI A/V Home Theater/MultiMedia Preamplifier the opportunity to receive a major hardware and firmware upgrade that will provide full 3D pass-through capability, as well as Audyssey MultEQ XT32, Audyssey DSX and Dolby PLIIz.  This is the 4th significant upgrade that Denon has offered to owners of its high-end products, underscoring the company’s commitment to provide its customers with the very latest, most up-to-date features and capabilities. The upgrade is scheduled for October; for more details on the upgrade, Denon owners may visit the company’s website (usa.denon.com/upgrades) and sign up to receive informational email updates.

What the Firmware Upgrade Provides

In addition to full 3D pass-through capability, which will allow AVR-5308CI A/V and AVP-A1HDCI owners to enjoy the growing roster of 3D movies now becoming available, the firmware upgrade includes Dolby Pro Logic IIz decoding for enhanced audio experience of front height channels. For an even more dramatic surround sound experience, Denon owners will be able to take advantage of Audyssey DSX with left and right height and width channels – a new set of algorithms that pushes the envelope in audio performance by synthesizing audio signals for new surround channels based on human perception and acoustical research. The result is a much more realistic and “present” soundscape, with more audio “depth,” ideal for both movies and music, with height and width channels that are integral to maximum performance of next-generation high-definition surround-sound systems. 

Features MultEQ XT32 MultEQ XT MultEQ 2EQ
Filter resolution (satellites) 512x 16x 2x x
Filter resolution (subwoofer) 512x 128x 128x N/A
Number of Measurement Positions 8* 8* 6 3
Adaptive Low Frequency Correction Yes Yes Yes N/A
Crossover, Polarity, Delays, Levels Yes Yes Yes Ye

The firmware upgrade also features Audyssey’s advanced MultEQ XT32 room acoustic correction system features a microphone (included) to automatically measure the speaker configuration and provide acoustic tailoring for the best surround sound experience, and provides quick and easy setup.  MultEQ XT32 is 32 times more accurate than the base MultEQ XT system it replaces with this upgrade.

“We are very excited to bring these leading-edge features to owners of our flagship AVR-5308CI A/V receiver and AVP-A1HDCI Preamplifier. Early adopters who purchased these components nearly 4 years ago bought them with the confidence that they would experience the very best home entertainment for years to come. This upgrade opportunity is yet another example of how Denon is committed to ensuring that our customers are ‘future ready’ and remain at the leading edge of all the latest performance-enhancing technologies.”

- Jeff Talmadge, Director, Product Development & Systems Integration, Denon Electronics

I say screw Denon.

I'll keep both my AVR-5308CI & AVP-A1HDCI just the way they are.

I second that motion!! Unless they would send the kit to me at 50% off and then I could do it myself

Denon has been keeping a tight lip on this. I believe its a hardware/firmware update but when I can confirm, I will update here.

I really hope they fix the SACD bass issue I discovered on the AVP when they did the last round of firmware updates. Haven't listened to SACD in my primary reference system now for like 6 months

FYI Gene. Since my last firware upgrade, The Internet Radio stations intermittently do not match the station on the menu. (example: Menu bar says Live Ireland 1 but it tunes to other station.) Wierd!

So who came up with the 5 post minimum… kinda restrictive … if I join the forum, I should be able to post pics right
from the gitgo… IMHO) I don't appreciate this restriction AT ALL!
we all went through the same thing as you, not really a big deal. You would be surprised how fast you can burn 5 post.

Status UPDATE on upgrade!

Ask them to have Denon check the serial number of the unit to see when / where it was manufactured… I had a strange firmware version on my stock denon receiver when I first got it.. was told that it was a european model…

I went ahead and flashed the firmware and it took… its been working fine ever since.. I even did a few more upgrades… not sure if this ‘anomaly’ has any bearing on the problem… but I thought I'd offer up the info anyway..

Just got another call from the shop yesterday. Despite being on the phone with the Denon “brain trust” and performing the firmware flash procedure several times just to be sure it took, the unit still would not pass video/audio thru the hdmi ports. He was told the video board may have to be replaced…
(and thats an additional $1000)

I asked him if he tried every HDMI input port, and oddly enough he did not… When he tried them all out, he discovered that the only the 1st three HDMI inputs were having the trouble… the next three HDMI ports do pass the signals… (YAY!)

After another call to the Denon Brain trust, he was told that there are two chps on the video board that each control Three of the HDMI INPUTs.. I have a pic, but the site does not allow me to put it up… (I only have 3 posts and you must have 5)

So who came up with the 5 post minimum… kinda restrictive … if I join the forum, I should be able to post pics right
from the gitgo… IMHO) I don't appreciate this restriction AT ALL!

oh well, looks like superfluous posting rules will deprive you of this pic… a pity …
(time to find an alternate forum to post it on… sorry)
