Topic: R4 run times

[boa]

I didn't think to mention that I run the R4 sitting on its feet with a baby comforter folded underneath and over the top of it. I did not have it resting on anything other than the SBD console the one time I ran into the "HDD Too Slow" error.

Based upon Sleepy and Nick's feedback along with Edirol's response, the error that I sustained could easily be explained.

Do most run the R4 upright in a bag or flat on its feet?

[Nick Graham]

The night I had errors it was kind of at a 45 degree angle propped against my main bag, Monday I had it facing staright up in the bag it came with...

I ran it out in the open, on a hard surface within a couple feet of the subwoofers built in under the stage at several very loud shows and never got an error.

I'm sure vibration is the root cause, but there must be a qc issue that is causing problems more frequently in some units than with others.

same here.  i've run it onstage, flat on its feet w/o any problems.  I typicaly run it in my bag standing straight up.

[Nick Graham]

Well, Round 3 with the R4 turned out perfectly too. I ran it flat on top of the bag it came with as a form of "shock resistance", and did a "Check Disc" between each set - and managed to pull 4 very loud sets (about 5 hours total) at 24/96 no problem.

Hey guys,
I just bought an r4 and I'm hoping to have it by friday so I'm researching.  Seeing all this hdd too slow stuff I'm wondering about power people are using.  Couldn't the problems also be caused by the hd not getting enough juice?  Louder shows would pull more juice with the pres, more power hungry mics would drain faster and things like multiple battery's linked (ie jasons 3@2000mah batt system vs 1@6000mah) would actually allow for a heavier power drain.  Is there a link to powering issues during failures.  Has this ever happened on wall power or internal aa's.
    Just thought i would bring this back up and see what the solutions are.

have these only been tested with 9v or is there thought that they can go 6v-12v like the ua5?

dude,

it asks for 9v on the input, the power supply that comes with it outputs 9v, the manual specifies 9v

why would you want to run anything but 9v?

its not like 9v is some exotic or expensive power source...give it what it wants!


=====
and people on this site wonder why they have all the "strange bugs" that they do when they try to do stupid shit like power a device designed for 9v with a 6v feed

chill out boogie... it was a simple and logical question.  I've got 2 @ 8.4 / 3300 mah rc batts that I'm curious if I can use them.  I'm just wondering if there is a power range and if it is the same as some edirol products.
     Anyone have anything constructive to say about voltage?

I can't say for sure Matt, but since the UA-5 brick and UA-5 both list 9-12 and the R-4 runs on 9v internal and brick puts out 9, I'd be afraid to run it on 12.

I ran the shit out of the demo I had and never got an error, even with 5hrs straight at 24/96 for the Jammys. So it's safe to say that batt power is not a direct cause of drive issues.

Thanks jason... I forgot that the ua5 actually listed 9-12.  I was thinking it just said 9. I have 2 3300 mah 8.4 v rc's and a 5400 mah 9v dvd batt.  No big issue for me except for helping with potential discharge rate issues.
      As for the power thing, I'm thinking you were on the right track.  Discharge rate can be a factor with some gear and running 3 2000mah batts in parallel is a best case scenario.  I'm wondering if the other batt configs were the cause of some issues... track record seems wierd on this unit.  I guess I'll be able to make my own assessments soon enough.  If I run all 3 of my batts togther (like I ran my last rig) I will be at 8.7v (I think... but I can't remember how to do that math exactly).  I'm sure that would be fine or at least nondamaging to the unit.

Thanks Jason

AFAIK, Nick ran the r-4 with just the 5400mha 9v dvd batt and had no problems either. That batt alone should give you enough run time for a whole show.

cool... I think I read that in his review over at nickspicks.  I may do som festi time this year and I'm preplanning.  I have quite a few battey options though so I should be OK.  I guess I'm just curious about the problems people have had.  Hopefully mine will be glitch free as well.

The 3pk of 2000mha 9v rc packs from batteryspace was the best powering option I came up with.

I got the smart/fast charger and 3 3pks for around $100 from their ebay store.

no, i don't think so.  consensus remains that 'HDD slow' only pertains to HD vibration.

  Louder shows would pull more juice with the pres,

is this even true?  phantom power is either on or off, i don't think there's variable drain depending on the SPL.

Has this ever happened on wall power or internal aa's.

the one time it happened to me i was on AC power.

and i'm with boogie, just feed it the 9v it very clearly states it requires.

[mmmatt]

Cool.  Thanks guys
