XDA-2 only works at second time

[tf11972]

Hello,

my name is Thomas and I am a german Emotiva customer. After a XSP-1, which satisfies me, I bought a factory renewed XDA-2 last September. And that's the problem with it:

Nearly every time the DAC doesn't work at the first time. I have to turn it off and on (sometimes three times) and after then it works fine (I am using a Logitech Harmony One). The display shows the correct sampling rate from the beginning and I can switch all the functions, but no signal comes to my preamp. Also the headphone amp is quiet.

In October I contacted the support team from Emotiva and after several mails I got a replacing mainboard. This didn't work at all, so I sent it back.

In November I got the message that the mainboard was repaired and would be sent back to me. But nothing happened.

At the end of January I sent a new mail to the support in order to ask for the process. But no one answered.

Today I made a test again: I turned on the other devices manually and the XDA-2 with the original remote - working. Then I switched off and on electrical power and turned it on with the harmony - nothing. The next times it worked. After several hours without electrical power the known issue.

Could the cause for the issue be my harmony? I assumed the remote codes from the Harmony database, maybe it should learn the codes manually? Otherwise I have in mind that with rising temperature of the device the issue doesn't occur.

I hope someone of the support team is reading here, I am slightly angry

Thanks in advance and best regards from Germany
Thomas

My problem is similar than this one, but my cell phone is wide away:

emotivalounge.proboards.com/thread/36995/xda-2-stuck-relay-problem

Shall I open the device and knock on the relays?

I had a similar issue with my xda2. Emotiva replaced it. There was a bad batch of the xda2's. Your best bet is to call them. They're much more responsive that way.

[tf11972]

Thanks for your answer. I still run several tests again today, but when I get no success, I try it on the phone.

I have now contacted a technician from Emotiva on the phone and he told me, I get a new mainboard.

Emotiva support is normally very good with sending spares to non USA locations to effect repairs, you just need to find someone that can install it for you if you are not comfortable with doing so.

I have in the past fixed many Emotiva units...but only a few have I had to repair with locally sourced parts due to board level troubleshooting. Good luck with the XDA-2.

[tf11972]

Now the telephone call is three weeks ago and I haven't got a new mainboard. Also no reaction to an email last week.

Can anyone tell me the type of built-in relay (it's complicated to pull out the XDA-2 out of my rack only to look inside)? Now I am at a point, I change the relays myself.

So, given you say it works fine with the Emotiva remote and not with your Logitech, this leads me to believe your XDA-2 is fine and that you have something programmed wrong with your Logitech.

I would deeply investigate the Logitech's setup. For starters, when the Logitech turns the XDA-2 on, what input is it looking to? What input is your XSP-1 looking to?

Mark (PS - what part of Germany are you in? I visit the Frankfurt area a couple times a year...Bad Soden. Very nice place, and I visit by hifi friends in Bad Soden and Hoffheim while I am there for some listening sessions.)

[tf11972]

I thought my Logitech caused the issue, but after several tests the DAC shows the same phenomenon with the original remote. Turn it on - sometimes a signal passes through, but mostly it doesn't. Turn it off and on - it is working.

[klinemj]

Then it is time to call them instead of wait for email.

I hope I have more success at the second time.

I had similar issues with my XDA-2 and found that powering up the XDA-2 "last" in the start up sequence fixed the issues.

Not all of my sources were particularly "finicky" about the start-up sequence, but my Mac Mini was very particular to being started "before" the XDA-2.

You might want to check the programming of the start-up sequence of your Harmony. If the XDA-2 is not last (and I'd even add a delay if you can), make it so and see what happens.

For what it's worth, the DC-1 does not suffer from the same "issues" and performs flawlessly in all regards.

Hope this helps.....

I own several XDA-2's and I have not encountered any issues with any of them. I suggest as others have, call them. Don't waste time emailing.

My XDA-2 does the same thing.

If the unit turns on, it's not the remote. If it's showing a sampling frequency, it's not on the wrong input.

It seems to be a stuck muting relay. Turning it on and off one or more times should unstick it.

I've often weighed the inconvenience of unhooking it and boxing it back up and shipping it vs hitting the button another time. I'm sure at some point I'll send it in..,

I have already tried this, but it had no effect.

My hope is, Emo sends me the replacing mainboard soon after the second telephone call last monday.

Now I think, Emo has forgotten me, so I decided to help myself. I disassembled the device und looked at the relays. The manufacturer is Huigang and the type is "HRS2H-S-DC12V-N".

I know the XDA-2 Gen2 has other relays with a grey colour. Does anybody know the type? Otherwise I order the Huigang.

Hi, if you do this, you risk voiding the warranty.
I suggest giving them a call rather than an email. They tend to respond better that way. They are open right now

If the XDA-2 detects the signal correctly, and shows the correct sample rate, but sometimes simply doesn't produce audio, then it is almost certainly a logic problem on the main board.
(It is possible for this sort of problem to be caused by a signal flooding the remote control pickup on the front panel and confusing the processor, but it's very rare.)

To confirm whether the remote control itself is defective, SIMPLY TURN THE XDA-2 ON MANUALLY SEVERAL TIMES.
If the problem STILL happens when you turn the XDA-2 on manually then it isn't the remote control itself.
Even though it's rare, it's still possible that some IR signal hitting the front panel of the XDA-2 could be confusing it.
To rule that out, temporarily remove the remote control from the area (or cover it), or simply drape a heavy towel over the IR "eye" on the front of the XDA-2 to block it (it's the little circle to the left of the main display).
You could also temporarily try the XDA-2 in another location.

If the problem still occurs with the IR eye covered, then it must be something inside the XDA-2 or in the computer.
And, if we're reasonably sure the computer is not at fault, then that leaves the XDA-2.

1)
I don't know what happened with your support case, or how it slipped through the cracks. (I sent a PM with my contact info; e-mail me with the particulars and we'll get it sorted out.)

2)
The XDA-2 has several relays in it; and NONE of them is involved with the muting (which is handled by several transistors).
(I don't know precisely what's happening, but it's almost certain that it ISN'T what you think.)

3)
If you start changing parts - without authorization and without information - you WILL void your warranty

Hi Thomas,

Your remote may have nothing to do with the problem. Can you describe your setup? What is your source? Your computer? How is your source connected? USB? Coax? etc.
