Have had one of these for just a few days.  Previously used a Sony D8 dat with core sound binaurals w/battery box - bass roll off.  The internal mics are very sensitive and will try the attenuation settings.  I'd like to get it working with the core sounds too though.  Levels are way too low when plugged into the mic in at 00 db gain and 00 db attenuation.  Saw someone mention a built in preamp but don't see a reference to that in the manual and don't see a reference to it in the menus.  So are they accessed automatically? Can I set it? 

Otherwise do I need to get an external preamp or new mics?  Stealthy recommendations?

Thx

I am sorry if I am asking the obvious, but did you use the battery box between the mics and the recorder?  If not, did you turn on the plug-in power from one of the pre-set menus (see page 52 in the manual, http://www.d-mpro.com/users/getdownload.asp?DownloadID=398)?  The default setting in all three pre-sets is "off".  If so, did you check to make sure the battery was fresh?

I have used some small electret mics (Church Audio STC-11's) directly into mic-in for a couple of shows and the results were pretty good (better than expected).  Levels were definitely high enough with the -24 dB attenuation setting and gain in the neighborhood of -10 or -12 dB.  The Core Sound binaurals should also work, I think.

I did try it with and without the battery box and with/without the mic power on.  Just put in a new battery into the box so will give that a try later.  Do the Church mics need a battery box or ext pre?  We record anything from an acoustic folk show to loud arena rock.  Looks like you got decent levels and even had to go -24db att.  I tested the CSBs with a local bar band last weekend and couldn't get levels more than ~-20db at 0 attenuation (high sensitivity).  Was I brickwalling?  Maybe I should've had it at -24 db. Don't hear any clipping though.

The built-in preamp is automatically engaged when you use the mic in jack, like with most recorders.  I haven't had any problems getting a good (-6dB) level with no attenuation using AT943s plugged directly into it with mic power enabled, even at acoustic shows.  Maybe your Core mics are exceptionally low sensitivity, or it's possible you got a defective recorder.  I would test it with another pair of electret mics.

I changed the battery in the bbox.  Took everything out to the car at lunchtime (I'm on the West coast) and did some testing.  Levels are MUCH better now.  So now the bbox has a sticker on it w/today's date on it  ;)  Did notice that the internal mics sound brighter than the external ones.  Is that typical? Not sure if that's a good or bad thing at this point.  Gotta play my sound samples on something other than earbuds.    Thanks folks!

Internal mics are no exactly the strongest feature of the PMD 620 ( or any other hand held recorder as as far as I'm concerned). Your external mics will always sound better. So it's not a good thing/bad thing issue. Hope that helps ;) Enjoy your gear.

Firmware updated for me.  BTW, I first tried a 16 MB SD card which only allows for a FAT file system.  No dice.  I then switched to a 1 GB card, formated with a FAT32 file system and tried again with success.

Hi everyone

My first post! Just got my PMD620 (It's was a hard time to come up with a choice :)) The PMD620 came with 1.xx firmware and just updated to 2.34 without any problems. Now the anoying latency on the headphones is gone !
Now I'm doing test recording and playing with the machine. I'm mainly going to go LINE IN, but i've noticed that when you have no signal coming, the meters on the PMD always mark around -50dB, even if you lower down the rec level to MUTE it's still marking something around -60dB, Is this the unit's self noise? Can someone else with PMD620 confirm that his unit his doing the same thing? It would be nice to know if this is normal or it's my unit that's defective.

thanks a lot!

Eric

There's a noise performance chart on the 620 in this link, along with some other units:
http://taperssection.com/index.php/topic,97231.msg1333626.html#msg1333626

I haven't actually used a 620, but from what I've read its' noise floor is a bit lower than the R09.

Mine does this too.  I don't think it is a problem, as I have used it quite a bit already with no troubles.  Or, at least, no troubles I didn't cause myself!

I guess it´s the "noise" of the room you are in which causes the -60db.

2nd: iPhone 5 + "Rode iXY" microphone/"Zoom IQ5" microphone

Hi

How can it be the room since I'm going line in? I'm not using any microphone

I've done some more tests:

1. Choosing line in the preset menu without connecting anything in the line in jack and putting the machine into rec-pause already gives me this -50dB reading in the meters.

2. Tapping with my fingers a bit hard in the internal mics gives me some meter activity as if the internal mics were actually not 100% disabled.

Any one else with a PMD620 experiencing this ?

I've been informed by Marantz that this is perfectly normal, nothing to worry about ;)

I think the -50 dB is likely just the bottom of the range the meter measures.

the PMD620 meters go a bit below - 60dB
Mmm... Even if Marantz says it's normal I think it's a bit too much
Does the R-09 or R-09 HR behave the same way ?

thanks for the answers

No. The R-09 levels stays very quiet. Bu appreciate the fact that the R-09 only goes to -40 if I remember right.
