battery box or 4.7 low sensitivity mod?
« on: December 04, 2018, 10:41:17 AM »
After I bought the Roland R-07 a few months ago, I still haven't bought any external mics, but I want to rectify that now. A friend of mine told me that I don't need a battery box and someone else told me I only need mics with a 4.7 low sensitivity mod. So I have 4 options really:

1. Only external mics with no 4.7 mod.
2. Only external mics with the 4.7 mod.
3. External mics with no 4.7 mod. and a battery box
4. External mics with the 4.7 mode. and a battery box.

I only tape loud shows, mainly (melodic) hard rock and sometimes metal. Which setup would you guys choose to go with the Roland R-07? Thanks in advance for your advice.

Both. You need the battery box to provide enough voltage to get the best performance out of your mics, and you will want low-sensitivity mics to avoid overloading the recorder's preamp.

Ideally, 4.7k modded mics plus the battery box/pre.  I use that setup with metal and it does just fine.  If I had to pick one or the other, I'd probably choose the battery box/pre.  I do know some people have run 4.7k modded mics directly into the R-07 with success (I think Darktrain did a Primus show with this setup...?).

On a related note (and I hope I am not highjacking this topic to too great a degree) but has anybody noted whether 4.7 modded AT853(u) cards are much more sensitive than 4.7 modded CA-14 cards?  I have sets of each and the CA-14s seem far less sensitive than the AT853s (to the tune of 15 dbs) when both are used with Church 9200 pres and M-10s (line in).  Sorry again for the stray thought.   

I have the exact same sets of mics, and haven't noticed this kind of discrepancy.

Odd. In my case, I get the same levels on the M10 (line in) when I set the Church 9200 pre at 15 dbs for the CA14s and at 0 db for the AT853s.  May as well use a battery box for the AT853s.

Here are my suggestions, in order of my least preferable setup to most preferable:

1. 4.7k modded mics
2. 4.7k modded mics with battery box
3. 4.7k modded mics with preamp

I bought a used Church Audio 9100 preamp from the yard sale and it has been perfect for a small setup. Here's my "low-pro" setup:

AT-853 Mics (4.7k modded) > Church Audio 9100 Preamp > Sony PCM-M10
Mics: nbobs/480+ck61/62/63; C568EB; MKE2
Pre: FP24
Recorders: MP6; A10

I just last night used the AT853s and CA-14s from the same position, both with battery boxes going into M10s line in with the same gain setting. The resulting levels were exactly the same.

Are you absolutely sure the 853s are modded?

Wow. Could the mod make that much of a difference in sensitivity across the board?

Whether or not you need a battery box or 4.7 k mod depends to an extent on the mics you are going to use.  Some are specifically designed for high SPLs or to operate to spec on low voltages.

I love the 4.7k mod mics and no battery box. Smaller setup and especially for stealth, it is great not to have so much stuff to get in to the venue.

Very grateful Darktrain did the mod for my AT853s. The sound is absolutely killer and the mics can handle any sort of SPLs.

That's great to hear Sevoflurane. Which deck are you using ? I also picked up a Darktrain set of AT853's and I'm looking to scale down for  >:D.

I run AT853's (Darktrain 4.7k mod) into the mic input on an M10, no battery box.  The sensitivity is perfect for what I do and the rig is compact. I couldn't be happier considering what I paid.

I use an M10 and a Tascam DR-05. Both work really well with it. I really love what Robb did to them. Here are some samples of them used with each deck.
