DPA 4061 - Which grid to use??
« on: September 12, 2007, 07:21:17 AM »
Tommorrow and Friday I'm going to see The Police in Amsterdam. I'd like to tape both shows in stealth mode. I'm using DPA 4061 mics..
The concerts will be @ the Amsterdam ArenA (Ajax ArenA), a football stadium 'famous' for it's acoustics. The sound is, in general, not very good. Other thing is, this venue is suffering from a 'stadium-syndrome', meaning the concrete-construction is 'eating' the bass.

Most of the time I'm using my DPA 4061 without any screens, but I was thinking on upgrading the lower frequencies a bit (at least, what's left of it). Should I use the Soft Boost Grid or the High Boost Grid?? DPA gives this info on them:

- Soft boost grid: 20 Hz - 20 kHz; 3 dB soft boost at 8 - 20 kHz
- High boost grid: 20 Hz - 20 kHz; ±2 dB, 10 dB boost at 12 kHz

Would one of the these screens be good for me in this situation, or is it better to use none??

Shorter screen with less boost seems more (better) in this case.

Ok, that would mean I should take the Soft boost grid.. Only thing is, it's the Higher/larger screen.. ???
Look at the dpa-site.. www.dpamicrophones.com

It's actually the shorter (barrel section) screen as shown in the graph from the site.

I´ll tape THE POLICE in Vienna next week with DPA4060´s. The venue can be really bad sounding IF the soundguy is on acid or other steroids HAHA..almost no low-frequencies at some concerts I attended in the past.
1st: SONY PCM-M10 + DPA 4060's + DPA MPS 6030 power supply (microdot)
2nd: iPhone 5 + "Rode iXY" microphone/"Zoom IQ5" microphone

Neither grid has a substantial effect on the low frequencies.  I'd use them without grids, then EQ in post to your tastes.

as far as venue acoustics, do whatever you have to do to get into the 'sweet spot' (generally at the point of a equilateral triangle with the two stacks and your spot in the crowd as the poits of the triangle. Or just inside this. Generally anywhere its really LOUD with decent imaging

I'll 3rd the no grids option.

You are suffering from lack of bass, then why boost highs with those grids? That is basically same as lowering the bass levels even more relative to the highs.

= no grids

When you remove the grid the mic is not flat... The grid is a way of controlling the polar pattern on the microphone and adding high frequency correction. There is a "flat" response grid that is used on the 4090, I have not seen this grid anywhere and I wonder if it is even available separately. But removing the grid means you lose top end around the 14-20k region. DPA like Sennhieser uses a cap as a means of acoustic equalization and correction for the capsule. That’s because it’s pretty hard to find such a small capsule that will be flat to 20k with out using some sort of correction. This is also the basic principal behind Earthworks that’s how they take a $4.00 capsule and make it flat. So when you look at the cap the longer the cap is the more high frequency correction is going (boost)

I personally would use the low boost cap.

So when would the soft or high boost grids be used?
Could I have a few senarios? 
I actually have the DPA-4060 mics and I mostly tape large arena concerts but will do smaller venues
if needed of course. I will do several STADIUM U2 shows this year as well.....any ideas?

Thanks,
Datfly

actually, the dpa omnis are probably not a good choice for large arena shows, you will get a lot of crowd noise no matter which grids you use, unless you can get close to a stack. as to grids or no grids, I use the shorter grids on 4061's all the time to provide protection for the mic elements.

Sonically, I suggest using the short grids in almost every situation. The only exception I might make to that is placing these mics on-stage, close to bright acoustic sources such as cymbals or brass.  Protection-wise it is always advisable to use the grids.  From AUD distances I would use them without a second thought and would still probably selectively boost upper mids and possibly top end with EQ regardless of what EQ the low end calls for.

Thanks for the replies.

Just to clarify..... do you mean the shorter screen top or the shorter barrel ?
Also when people suggest no grids does this imply to have just the naked gold top showing on the mic?

Thanks,
Datfly
