I have the same problem!!  Mine is currently in with a local tech that services for Roland.  I'll let you know the damage when I get it back.

OK, I am so tired of just coming here with stupid questions and problems.

(sigh)

But I survived the summer taping extravaganza, and the end result is: i seem to have fried the battery plug on my R44.

It works with batteries now, but does not accept the any input from the dvd cable or the power plug.
Tried a factory reset, but wasn't willing to risk much more than that.
I'm guessing that has happened to more than one person here, so I figure someone can tell me what I've done and what its going to cost me.

And now...

...that fall taping season begins on Monday!

Thanks again!

Happened to me too in the early R44 days - the local authorised service centre didn't have the service manual and as I now recall it, it took a couple of weeks at least for them to get hold of one, and then another week or so to actually fix it.  What the fix was I don't recall being told.  As for cost, I'm pretty sure it was a warranty job.

Well, the 4 screws on the bottom come off easily, but I can't make the center one budge, so its going to be someone else to fix it.
I'm guessing i blew one of those fuses by plugging in the wrong power source, but I can't be entirely certain.

Time to spend more money, I guess.

Funny thing is, it just preformed flawlessly for 3 hours, taking a digital feed from the acmV3 and powering dpa4061s, then, as i was schmoozing it up with the band, forgetting to turn it off, it saved the files and powered down on its own. The adaptor would have only been a backup for most shows I can make it to these days.

With the R-44 using the odd center-pin-negative AC input/adapter, I'm surprised it doesn't happen more often.  The Achilles heel of an otherwise solid deck.

I got the ac input fixed for $80!!  It was a local Roland Tech so I didn't have to ship it.

Well, the 4 scores on the bottom come off easily, but I can't make the center one budge, so its going to be someone else to fix it.

I feel like the fact you were using different mic patterns might have had something to do with it as well.  Not  necessarily the case but it doesn't seem unlikely that more people preferred cards over the sub wide cards from back of the room.

Yeah, that's pretty much my take away on it too.

In any case I've no complaints running straight into my OCM R44 without the V3 in between and this comp doesn't sway me from that.

I have come back with more questions.
While attempting to upgraded a brand new R44 to a concert mod, Doug noticed an intermittent problem:

"The combo jacks on channels 2 & 3 have intermittent 1/4" switches.
All 4 channels work perfectly on the 1/4" inputs.
When you plug in a 1/4" connector, there is a switch that takes the XLRs out of circuit.
It's that switch that is problematic on this R44."

He can either bypass the switches which cost 110.00 or replace the entire jack board which cost 350.00.

I don't really understand this, but I know someone here does. I don't currently use the 1/4" in part of the in jacks, but plug in XLRs into the same jack, as well as using the digital in.
Currently that's the way I usually use it: DIGI+ANALOG; Stereo x2. Sometimes, I'll do all 4 channels XLR; ANALOG, Stereo x2.

Now even as I type this, I feel that I should be able to understand it, but I just don't. I'm guessing that when I plug in all 4 XLRs, they aren't taking the 1/4" out of circuit, but if I should ever plug in the 1/4", they won't take the XLRs out of circuit. (I still don't understand what I am saying when I say this).

So basically, I have to decide what I need, since I don't need an additional $110 or $350 bill, but I want the machine to do what I want it to do.

Can someone clear any of this up for me so I understand what I'm talking about?

Thanks!

Those combo female XLR / 1/4" TRS input jacks are pretty common on a lot of gear.  I've never examined any of the working bits of those things very closely, but assumed on the R44 that they essentially used extensions of the same contacts within the plug for both XLR and TRS plugs.  That's what it appears like when you look at the jacks from the outside. 

I can see that as a commonly used combo jack there would be a switch inside them to accommodate gear where the XLR and TRS inputs actually feed different signal paths within the unit (like for a hi-Z instrument TRS input and low-Z XLR mic input), but the circuitry past the input jack in the R44 is identical for both types of input.  That's what the circuit diagram indicates, how the machine seems to behave, and the commonly accepted scenario around here. 

If there is a switch within each jack, it's not working should not cause any obvious functional problem in either failure mode (stuck open or stuck closed), as far as I can tell.  At least as long as the signal path isn't compromised for either input- meaning that either XLR and TRS input works.

I don't think you need to anything for the machine to work correctly with either type of input.
I stand ready to be corrected though.

Is he implying that channels 2 & 3 aren't working perfectly with the XLR inputs? I would think that it's a mechanical failure...it just seems unusual that you would have two go bad at the same time.

I think I also don't follow it. 

This is a new unit too?  Odd.

I've always used XLR's only but the prospect of ever using 1/4" and having that mess up the inputs has me a little spooked.  I guess I'll mentally rule that out.  My sbd stereo patch cable was RCA to RCA so I got those "bullet" adapters from RCA to XLR to run it into the R-44 the few times I did.

All 4 channels work perfectly on the 1/4" inputs.

I'd ask Doug this:

"Will this problem affect use of the XLR inputs in any way?"

If not then it doesn't matter and you don't need to do anything.  If it will then bypassing them effectively fixes that problem and you'll be able to use either XLR or TRS inputs however you like.

That's the $110 question I think.
