How do I reset the microprocessor or do a network reset?

When the APR is acting up or doing something strange, try the following steps before resorting to a microprocessor reset:

1. "Restart" - set the AVP to Standby and press/hold the power ON button until "Restart" is displayed on the front panel (resulting in no loss of settings).

If no joy, then ...

2. Soft reset - set the AVP to Standby and unplug the power cord for about 10 minutes, then plug back in the power cord and turn ON (resulting in no loss of settings).

If neither of the above resolves the issue, then you'll need to either do a network reset (if network related) or a microprocessor reset. You'll also want to reset the microprocessor before doing anything else if you purchased the AVP as an "open box" or demo/used/refurb unit to ensure all settings are returned to their original factory defaults. Prior to doing a reset, you can SAVE the config file to a USB thumb drive so it can be LOADed after doing the reset (SETUP - GENERAL - SAVE&LOAD).


Microprocessor reset to original factory settings (no change in current firmware version)

Note: In some cases where a single microprocessor reset did not resolve an issue, doing at least 5 in a row did.

1. On the front panel, turn OFF the power using the POWER button.
2. On the front panel, momentarily press and then release the POWER button (as you would when normally powering on the unit) while simultaneously pressing/holding the GAME and INFO buttons (under front panel flap).
3. Remove your fingers from the GAME and INFO buttons when “Initialized” appears on the front panel display.


Resetting network settings (the menu “Amp Assign”, “Speaker Config.” and “Video” settings are not reset)

1. On the front panel, turn ON the power by pressing the POWER button.
2. Turn the INPUT SELECTOR (left large knob) to select “HEOS Music”.
3. Press and hold the BACK and ENTER buttons (under the front panel flap) at the same time for at least 3 seconds.
4. Remove your fingers from the two buttons when “Network Reset...” appears on the front panel display.
5 “Completed” is shown in the front panel display when the reset is complete.


Note: Prior to doing either of the above resets, use the SETUP - GENERAL - “Save & Load” function (to USB drive) to save the details of various settings configured on the unit to include the Audyssey settings. The LOAD function can then be used after the reset to restore these saved settings.


Factory Restore (restore to original factory firmware version)

1 - Turn off the power using ON/STANDBY.
2 - Simultaneously press/hold the: "M-DAX" and "DYNAMIC EQ" buttons on the front panel and then press the ON/STANDBY button on the front panel. This procedure will take 15-20 minutes to restore to the original factory firmware.

For optimum fidelity and the widest dynamic range with lowest distortion, the AV7704 features advanced reference-class 32-bit AKM D/A converters on all channels.

Thanks for the AV7704 DAC info.
Also would like to know what DAC's they will be using in the new AV8804.
Anybody knows please tell.

As a side note, their pending flagship will be called an AV8805. It's safe to say this will happen with a price hike for several reasons. SQ wise, the 8802A will sound better for discriminating ears. Re: the DAC on the upcoming flagship. I didn't ask, but it is fair to say they will be partnering with whatever is/will be the top-of-the-line AKM DAC. Additionally, it seems most ubber spendy stand alone DAC's are now specing in the AKM brand.

Re: The 7704's timing. They finally arrived in CA last week and they are in transit to dealers that have ordered them. I expect to get my batch soon and when I do, I want to compare the SQ between it and the 7703. It will probably be tie. But I hope the NEW AKM's add some sonic value. I heard that the AV7704 was "re-tuned" with incremental tweaks. I'm going to ask my engineering contacts for specifics. We shall see... But their are always running changes specifically related to sound quality from year to year. What that means to the ear is another topic. Also, it is not the same DAC chip as the 8802A. The 7704 uses the AK4458VN. The 7702, mkii, 7703, and now 7704 all use an 8 channel DAC. But for the 7704, it now uses this one which they are touting as an upgrade (see http://www.akm.com/akm/en/product/datasheet1/?partno=AK4458VN ).

JD covered the bullet points. I'd highlight from his post the differences from the AV7703: The AV7704 now has Auro-3D included at no charge. Also the new 32 bit's AKM DAC's. Additionally, HDMI Diagnostics, and now eARC via future firmware update.

A lot of people are hearing the term eARC for the 1st time. it stands for enhanced Audio Return Channel . It's valuable for people who steam services from their TV like Netflix or use their TV's built in tuner (cutting the cable cord) to drive audio. So the AV7704 gets the audio signal from the TV and processes it for surround sound. Before, via ARC, you were limited to the amount of channels and bandwidth. With eARC (e stands for enhanced) It provides much higher bitrate audio PLUS more advanced audio formats. Most importantly, object-based audio such as Dolby Atmos and DTS:X.

Marantz 8012 vs 7704? I see the price difference is about 1K. Wondering what the 8012 would have over the 7704?

thanks in advance.
I posted this in anther thread. So there is some more info than is needed.


"The 8012 is a tweaked out Denon 6400h. Like the Denon 6400h, the Marantz 8012 will also be made in Japan. So the pending 7500h, 6400h, and pending AV8805 prepro will all be manufactured in Japan. All others will be made in Vietnam. It's important to note, the 8802A (which has become a better value because of vendor promos to dealers) still sounds the best in the line-up. Yea, the 7500h is going to cost even more than 8012. That price has not been picked/calculated or announced.

Back to the 8012 Marantz receiver. Basically, take the 6400h (which sounds wonderful) and give it the current feedback loop HDAM's, a better power supply, and a lower noise/RF shield "copper chassis". There could be other things, but that is the biggest difference. I'll address each item. I realize some people who spend a lot of time reading these forums know this, but I am typing it for convenience to others. Basically, the 8012 will use the HDAM's which are discreetly built operational amplifiers per channel and once of the reason why people like the new current feedback sound. I forgot to ask which version of HDAM they used (their are two versions). But I will ask. Also, the power supply is bigger which offers more headroom (helps better all specs including all channels driven). Finally, the copper chassis is functional at rejecting interference (i.e. a Faraday cage) PLUS the copper has low ohms per square that factually helps the signal path (noise). I mentioned this in another thread. The copper just so happens to look nice to some eyes and people assume it's a gimmick. Well, they used it for technical reasons. Sure, they made it pretty for marketing reasons too (two birds with one stone).

The "flagship" pending 7500h will be based off of the AVR8805. In other words, bigger badder DAC section and any key features that are pending on the 8805. I'm not at liberty to talk about what those are on a forum. But I've learned enough to know that I'm excited to get my hands on one. I was also promised that I won't be disappointed."

If you are paying $3900 for a 8802a you are way over paying a drastic amount. Do not get me wrong the 7704 sounds nice.
of course, but that's my point... same can be said for the 7704. I currently have a 8802A and wont be upgrading any time soon.

flaky network connection

I received my unit yesterday and was setting it up tonight.
The network connection is very flaky, sometimes works sometimes doesn’t. I have it set with dhcp but it looses the ip address. I did factory resets and network resets which don’t solve it.

Is anyone experiencing this? Any suggestions?
thanks

As far as I know, it is the same card as the 7703 which is extremely stable. The 7702 had plenty of network issues early on. Are you using wireless or an Ethernet connection? The Ethernet connection should be rock solid.

If you have a "wireless" configuration, you may want to consider using a "bridge" router (that sits between the primary router and the AV7704) as I had to do due to my primary router being on one side of the house and my Denon AVR being on the other side of the house.

The AKM AK4458VN has been used in Marantz 770X pre-pros since at least the 7702mkii. It's not new to the line.

The AV8802a uses the AKM AK4490EQ DAC, which is a two channel unit. The AK4490EQ is a much better DAC than the DAC used in the AV7703. The next chip up in the AKM line is the top of the line, the AK4497EQ, another two channel chip. If used in the next AV880X the AK4497EQ would be a step up, not a huge step, but clearly a step up.

The competing DAC's from ESS are better (SN, Distortion, filters), especially better than the AK4458VN, but they cost more to implement for maximum performance. Yamaha uses not the top ESS chips, but good versions, however their implementation doesn't get maximum performance from the DAC's. (Voltage output instead of current output is used.)

Thanks for the clarification on the 7703 versus 7704 DAC. :) In the August, 2017 AV7704 press release, they highlight anything new in red. On the cut sheet it reads:

 Auro-3D now included at no charge
 32 bit AKM DAC
 HDMI Diagnostics
 eARC (enhanced audio return channel) via future firmware update

Seeing "32 bit AKM DAC" I assumed it was a new. you know what they say about assume.:eek: So when I looked at the 7704's, 8 channel DAC, it said AK4458VN and didn't bother to re-look at what the 7703 used. Nope. It's not new. JD's initial post was staring at the same release but he was smart enough not to be fooled. Thanks for catching that.

Re: the subjective SQ of the AKM AK4490EQ DAC. For whatever reason over the past few years, models like the Bryston BDA-3 (US$3,495), the Hegel HD-30 (US$5,000) Aurender A10 ($5,500)all streamers by the way, have been picking the 4490. The AK4497EQ looks to be released about a year ago. So if it does sound better, I hope they spec it in. :)

My connection is hardwired. I’m not using wireless. I’ve tried different lan cables and router ports too, and I’m not having any connection issues with other lan devices so I doubt it is the router.

A streaming device has certain characteristics:

https://en.wikipedia.org/wiki/Streaming_media

One easy test for streaming in the audio world is does the device have an Ethernet port (and/or equivalent Wi-Fi connection) that is used to access digital media, that is; music? The Bryston BDA-3 has an Ethernet port, but the port is used for remote control, not for access media on a network. The BDA-3 has no DLNA capabilities, which is another test. In addition Bryston makes it clear that the BDA-3 is a DAC, not a streaming device. The Bryston BDP-3 has this capability, but is not a DAC. The two units together provide the functionality of a streaming DAC at total list price of about $7k.

This portion of the Stereophile review of the BDA-3 details the external connections to other devices, such as the BDP-3, that are required to move data (stream) from a network to the BDA-3.
