Thread: No Network Connection

I have a Marantz 7703 in our living room for HT and music.
I have been using it with Roon for a couple of years with no issue.

A week ago Roon stopped seeing it and at first I assumed it was something in the latest upgrade.

As it turns out the Marantz has lost its ability to make a network connection via either hard wire or WIFI. I have used the network setup process and a total revert to factory specs and nothing changes. I have called Marantz and all you can do is leave a phn # and so far received no response.

I have come to the decision that the network circuit has died.

What I am looking for is some device to connect to the Marantz that will be seen by Roon. The music from the Marantz is only background sound so the quality is not really important.

Any suggestions for a product that will fill this need?

Thanks Brad

I may not understand the situation so...… if memory serves Bluesound is going to become Roon ready, yo could add the Bluesound Node and use the digital out into the 7703 DAC.

You understand perfectly.

I happened to run across a Bluesound Node 2 earlier today. The thing I wasn't sure about was would Roon find it?
It has digital and RCA out so it would probably work if Roon will work with it.

Thanks

I ordered the microRendu and then my HT guy that is a dealer for Marantz reminded me that the DAC in the 7703 is accessible only through the network section of the amp.

With that, I need a streamer connection with a DAC in it. Since the music is background for the whole house I am going to try a Sonos model he is recommending. Another issue is not having to reprogram our RTI remote system. So, I contacted Andrew and canceled the order.

If this isn't acceptable in the end then, it guess a DAC end point. I'm guessing this will do what I need though.

Thanks for the suggestions.

You mention reverting to factory specs, but just in case that didn't mean a true factory reset, you could try performing one by following the instructions in the manual: resetting factory settings.

I can't believe that information to be accurate, I would try one of the coax or optical input using something you have around for transport. I can't understand how a network circuit/chip whatever would prvent one of the inputs from working with the DAC. In fact, if that was true you shouldn't be getting sound from any of the HDMI either.

And, if the Node or similar wouldn't work, how will the Sonos hook up? I guess you can't blame the guy for wanting to keep you as a customer but his answer isn't making sense to me.

Not complicated and it will send bit-perfect signal to your DAC.

And if the Marantz has a USB input, you don’t need the HAT and you can save an extra $40

You may not hear much about it but streamers from well-known brands costing well over one grand are based on the inexpensive RPi. Maybe even your Marantz has an RPi computer inside.

Unfortunately it doesn't have any USB connections. I don't know what an RPi computer is. How would I figure that out?

Yes, we tried that along with 2 other for other resets but, thanks for the suggestion.

I have worked with him for a few years and he has always gone out of his way to find solutions to problems to save me money but I have delt with other that have not been honest.

According to what my guy described the Sonos has a basic DAC built into it. I don't know the model so I have not been able to verify.

I agree that it doesn't make sense that the DAC is not accessible. I have reached out to Marantz and the phn # has a recording saying they have technical difficulties. The customer service via email or chat has a similar message.

You don't need the 7703 DAC at all, you use an external dac instead, and if you pick a wise choice it is better then Marantz has. This Marantz picks up the analogue signal and only amplifies it to your speakers.

Yes, the streamer has a DAC in it.

I will speak with him again about it as it doesn't make sense to me either.

Did you just update the Marantz?

Can you verify that other parts are working, not just the network is failed?

Marantz / Denon AV receivers do not have USB DAC input. They have USB type-A port but it's for USB storage:


To access Marantz / Denon AV receivers internal DAC, you'd need to use coaxial or toslink or HDMI audio (not i2s).

If you use a PC for Roon Core, you can try connecting the PC HDMI output to the Marantz HDMI input. It may need some manual Roon configuration before you'll get sound though.

Hi Peter,

No I had not updated as my HT person warned that current updates had caused problems for most of his clients. He has dropped the Marantz line due to this issue. I did check on updates and it showed not updates available.

Everything else on the Marantz works fine.

I have not made time to try connecting my Oppo via digital out to see if it will play music this way. If it does then the DAC should be reachable as you suggest.

I am hoping to use my streaming signal in my listening room via ethernet as I had always done. I would bring my iPad to the living room and select from my server or Qobuz via Roon programing.

I'm slightly surprised he dropped Marantz (= Denon). With Onkyo (= Pioneer) financials causing delisting, that leaves buyers only one major alternative: Yamaha. In spite of the firmware updates, I still see Denon / Marantz as market leading AV receivers, and will likely need to buy one in the coming years.

If your Oppo is 203 or 205, you can simply use the Oppo as a Roon Ready endpoint, with analog or digital output to the Marantz.

Unfortunately my Oppo is the first gen BluRay 83 so that will only be good for the digital out to test the Marantz.

He said almost every time an update was done it had a ripple effect on other parts of the unit. Marantz would take no responsibility for the issues so he went with Yamaha.

I have called numerous times and the Marantz support has a message saying they are having technical difficulties and to leave a number. After 4 weeks of leaving a phn #, no response.

If the digital input of h 7703 works then you know you could use the Node or other device you ordered.
