Hey all,

maybe it is a setting issue, but i cannot get my right channel to work with the 48 v phantom on/mic on .  my setting was for stero, mic in on the preset.  anybody have any ideas. thanks

If the preset is selected for stereo and you have the switch set all the way to the to mic/p48 spot, I think you are setup correctly. I got the warm mod from Doug also and I did some testing over the weekend. I did notice that when I powered up the unit and hit record/pause immediately, one channel powered the mic on noticably sooner than the other one, but I really did not think much of it. You really should send Doug an email if you cannot get the right channel to send phantom.

Finally got to spend some time in the field with my new rig (Senn 8040 > remote cables > Oade Concert PMD661), in fact it got quite a workout this past weekend!  A little bigger than my old stealth rig (AT943 > BB > Oade concert PMD620), but still very compact and it sure does sound pretty!



I can confirm that this combo will run for at least 8 hours on a fresh set of Energizer lithium AAs, and generally I'm very happy with the results in a variety of recording situations.  I think the concert mod may be a better match than the warm mod for these particular mics as they're not nearly as bright as AKGs.  I used a PNY 16Gb SDHC card for all these shows and didn't have any problems, although I was only recording at 24/44.1.  A couple of people have expressed interest in hearing samples, so here are a few 24-bit FLACs.  These were all recorded with the attenuation setting at -12dB, no editing other than fades and adding some gain.

here's another battery test.
Duracell NiMH rechargeable AA's (2650mAH).
using beyerdynamic CK930's, phantom power on, OLED screen at the dimmest setting (which is still plenty bright enough to easily see in the dark), deck set to 24/96.

3 hours, 52 minutes.  just shy of 4 hours.  1 hour and 12 minutes longer than my test with regular Energizer Alkalines.  that's pretty good, and certainly long enough for a typical 2 set show (though maybe pushing it for an opener + 2 set show).

also, of note is that I was running 24/96 on my PNY 16 gb sdch (class 4), with autosplit off.  after the deck died, I had three files, the first two were 3815MB, which in the computer world (of 1024MB = 1GB) is 3.7256 GB, but in the world of 1 GB = 1,000 MB = 1,000,000 KB = 1,000,000,000 Bytes, the comptuer file size of 3815 MB = 4,000,317,440 Bytes.  So that's the 4GB limit after which a new file is started.  Anyway, a bit of a tangent there.  I have two 3815 MB files, and a 27 MB file.  It looks like the last file closed properly, and no issues with 24/96 on my PNY card.

I've also decided to organize all of the battery tests into a list with standard info...  I went through the previous 25 page thread, and I think I got them all.  However, if I missed one of the battery tests, please let me know and I'll add it to the table.

  • Battery Type
  • Battery Capacity
  • PMD-661 Phantom Power
  • mics used (current draw per mic)
  • run time

  • Battery Type = Tekkeon MP3450
  • Battery Capacity = 10,000 mAH (5V setting)
  • PMD-661 Phantom Power = on

  • mics used (current draw per mic) = beyerdynamic ck930 (4.6mA)
  • run time = 2 hours, 40 minutes

  • Battery Capacity = 2,650 mAH
  • PMD-661 Phantom Power = on
  • mics used (current draw per mic) = beyerdynamic ck930 (4.6mA)
  • run time = 3 hours, 52 minutes

  • Battery Type = Energizer Lithium AA's
  • Battery Capacity = ??

  • run time = 8 hours

  • Battery Type = Energizer E2 Lithium AA's
  • Battery Capacity = ??
  • PMD-661 Phantom Power = on
  • mics used (current draw per mic) = Schoeps cmc6/mk4 (4mA)

  • Battery Type = Energizer Lithium AA's
  • Battery Capacity = ??
  • PMD-661 Phantom Power = on
  • mics used (current draw per mic) = Sennheiser MKH8040 (3.3mA)
  • run time = 8+ hours

  • Battery Type = Energizer Lithium AA's
  • Battery Capacity = ??
  • PMD-661 Phantom Power = on
  • mics used (current draw per mic) = Neumann km184 (3.2mA)
  • run time = 6.5 hours

  • Battery Type = Duracell NiMH rechargeable AA's
  • Battery Capacity = 2650 mAH
  • PMD-661 Phantom Power = on
  • mics used (current draw per mic) = Nevatons (??)
  • run time = 4 hours

  • Battery Type = Energizer NiMH rechargeable AA's
  • Battery Capacity = 2450 mAH
  • PMD-661 Phantom Power = on
  • mics used (current draw per mic) = Neumann km184 (3.2mA)
  • run time = 5 hours

  • Battery Type = Energizer NiMH rechargeable AA's
  • Battery Capacity = 2450 mAH
  • PMD-661 Phantom Power = on
  • mics used (current draw per mic) = AKG 568 (<2mA)
  • run time = 5 hours, 15 minutes



Alright, so far it looks like the non-rechargeable lithium AA's are better than the NiMH rechargeable AA's.  both of which are better than regular alkalines.  And going to an external battery solution, very long run times are possible.

Again, if I've missed any battery test reports, please let me know and I'll update this list.  Also, I'll try to keep it updated moving forward as more people do battery tests.

Jason, Great work! Good to know the runtimes for the Duracell 2650s, because that is what I will be using in my 661. Just wondering, since you have this testing process down with good documentation, could you possibly repeat the test running XLR Line in? I plan to keep running a pre in front, and also will be running the occasional SBD, so I am curious how much longer the 661 will run on line in, without the added power drain to drive the internal mic preamp and supply phantom power to the mics. If you are able to incorporate a line in test into a future battery trial, that would be really appreciated, I am certain.

Thanks!!!!

I can't do that right now.  I don't have an external pre-amp anymore, and I don't even have a set of RCA > XLR (m) cables to run something from my home stereo into the PMD-661.  I would assume that the phantom power uses a significant portion of the total power draw, so if you were using an external pre-amp and not using the PMD-661's internal phantom power, I would expect a sizeable increase in battery run-time...  but I just don't have the gear to test it now.  Why don't you run the tests and share your results with us?  I'll update the list after you do :)

Sure, I can try to do something to test the power used for just XLR line in. I definately agree that without the phantom, it's got to increase the run times significantly. I will try to work out a test of the XLR line in using the 2650 Duracells this weekend, and post the result. Whatever proportional increase in run time with internals I find should apply to all the other powering methods you tested.

Got my new Sandisk Extreme III 8gb SDHC card in the mail yesterday.  I ran it last night for about 4-5 groups for 3h 45m on one track with no problems. 

Also, my battery level was still full running internals (Sanyo AA NiMH 2700mah).

I recorded LosBlancos in Rome, NY tonight. I used the Neumann 184's > OCM PMD 661 @ 24bit/48khz. came out fantastic.  Ran the mics 7 1/2 ft XY, 10 ft from Stage. Very Happy with the results, I will post samples and torrent later. Everything about this deck is easy to use. the Neumann's sound really nice with the OCM.  TY Oade Brothers   8)

anyone measured the phantom voltage on theirs? 

I'm getting ~44v.

I just measured mine.  One channel was 44.7v and the other was 44.9v...  Don't forget that the phantom voltage spec is 48v +/- 4v, so even though it seems low, it is still within the phantom voltage specification.

I'm not really alarmed, just figured it was worth noting.  My mics operate on anywhere from 9-48v so I'm certainly not worried. 

Is there an easy way to test under-load?

I am also not really concerned (the beyerdynamic's spec are from 12v-48v), but I agree, it is worth noting.

for mics with specs only at "48v", I don't know of any real way to test if the mics are getting enough voltage (of course, keeping in mind the +/- 4v, and also keeping in mind that the specs are for the open voltage, and that every mic will see a lower voltage when the circuit is under load).  From what I recall, there's no real good way to know how an underpowered mic will operate.  Some mics will just have a lower max SPL that they can handle, while other mic's performance drops off more significantly.
