Double Bass DPA 4099 vs AMT SP25B

Yes maybe, but I don't feel problems with unwanted vibrations. It works well and easy to mount. I tired to mount on the tailplace, it looks very cool, and sounds good, but I find it doesin't seats stable enough in that location, maybe I try again. I think other clip-on mics like ATM350 is much least option to mount on double bass, than this DPA mic.

i have that unstable feeling about the mount in several places that i tried too. this afternoon i experimented with using a rubber band to help secure the mic to whatever location i was using and it made a very big difference. in many positions i felt that the mic was about to fall off, but the rubber band added a great deal of stability. i think ill always use one.
one thing ive noticed is that this thread seems to be focusing on the mounting issues. i think there are mounting issues with this mic, but with just a little experimentation and some rubber bands i think this can be overcome. it would be nice if it were a complete package from the manufatcurer but bassists always seem to come up with their own solutions anyway. aside from the mounting concerns, how do the owners of this mic feel about the sound and perfomance of the mic itself? i havent used it on a gig yet, but so far i have to say that the mic alone is worth it for me. im getting very loud with this thing with no feedback. im not sure how bleed will be on a gig, but i have to assume that if there were going to be alot of bleed then there would also be more feedback issues than im having. time will tell. position of the mic is very critical so far in my experience with this mic, but thats probably true with all mics.

This is another mounting options with the guitar version. Now I find the way to avoid the unstable feel. The only benefit in the bridge mounting, is the very nice stringy sound what this microphone really can do.

actually what i really like about the mic, is that by tweaking the placement some you can have less of that "string sound" and more of that gut "puff", if you've guts on the beast.

I got mine today.
I've been using a Beyer M88 on a stand. I set that up like usual (in my practice room, not a gig) along with the DPA. I put them both into a recorder so I could see a meter and I could match the levels. So now with essentially the same volume coming from each mic, I could listen for background noise. With the Beyer, I could hear more "room" while the DPA sounded more isolated. Subjectively, I think I preferred the sound of the DPA - but the Beyer is a great mic too. I sang while playing and my voice was more audible in the Beyer track. Not a giant difference, but certainly pretty significant. We'll see what happens on a gig soon.

Do you own the DAD4099 ( built in hi-pass filter ) or the DA6001 ( flat ) adapter?

Since the 4099 cuts off anything below 80 HZ Mike recommends the flat adaptor for Double Bass. It's really designed to use with the Violin. I got mine this weekend. I'll post stuff when I play out with it. It sure is tiny. That's a good thing.

Yes, I got my with the DAD4099 accidentally, since I didn't know anything about that 80hz filter built in the adapter. I talk to the guys at the local DPA dealer, they say I can buy the 6001 adapter for additional $100, or easy to remove the hi-pass filter from the 4099 by a technician. I can not understand why DPA couldn't apply a small switch on the adapter, to choose you need it or not, like at other mics.:confused:

That's a great question. In my experience, the HP filter at 80 hz should be fine anyway, but the option would be nice.

yes, most high end mics give you a switch so you can turn it on or off. having said that, i have the adapter without the high pass filter and i only use the mic with an external high pass filter in my preamp turned on. i dont think getting the filter in the connecter would be a problem. it seems to be necessary to reduce feedback and handling noise which were a probelm for me without it.

here's the best solution i have found so far. its very secure, and i can put it anywhere i want. kind of expensive when you factor in the h-clamp, but im just viewing the dpa as a super light mic that wont stress the h clamp or make it fall like some mics can, and it sounds great

In most of the situation the HP filter is recommended, but in some situation is disturbing. The mic sounds very good even with the HP, but below the A string getting very shy! Ok thats not a problem if you blend with a pickup and getting the low end from the pickup and capture the mids and highs with the mic, this is a very good method in live, but the fixed HP is narrowed the possibilities to this. I use the mic FOH, in most of the mixers of today has HP, some has with adjustable frequency. I think in many situation don't need to cut the lows below 80HZ, maybe enough from 60HZ. You can see in the diagram, the built in HP start to cut higher than 80HZ and cut almost 10db at 41Hz where our open E sounds. The switch would the real answer, but since there isn't, I will go without the built in filter, the soundman will apply if needed.

Agreed. The Focus amp I use has a High Pass filter with a variable takeoff point. I'd rather make that choice for myself on the gig rather than defaulting to a preset thing that was undefeatable.

I'm on the fence on this issue. I'm planning on demoing one of the new Headway pre/blenders that uses the same EQ on both channels. I could see this working either way if you weren't using an amp with two independent HP filters. Either way, the mic looks very interesting!

Even with that Headway the high pass is after the summed signals of both mic and pickup. I'd still run that mic full range and roll after the summed input. That cut starts way up in the 250hz range middle of the fingerboard on the G string. I see little advantage to having separate high pass for both input signals. I don't mind having it, but I could live without it. The only other issue with that Headway is you can't work phase with either line or mic depending on what you need, just the mic.

Even so, I recommend the 4099 mic! This is the best and most usable in live mic I ever tired. I just recommend to use without the built in HP. This Headway blender is interesting, and in the HP section of this blender has an option for URB and rated at 41HZ.

no comments on my crazy contraption? im moving the mic all over the bass now. trying out every possible spot. i couldnt do this before and it feels totally secure. before in some positions it felt like it could come off at any minute. i dont have to torque the gooseneck so much anymore either.

Well...it's a bit much for me. Not that I'm a purist by any stretch but it's just not my style. Let us know where the sweet spot it on your bass so we can try ours there.

I see why you would say this, but it's one of the features I love about the Focus 2 (III). I find that the HP on the mic channel helps get more usable volume, whereas the HP on the pickup shapes the tone more. In either case, the gents at DPA would do well to put a switch on the thing like many much cheaper mics have.

I don't have the 4099 yet, so I'll reserve comment until I have one to try. I'd probably try to find the magic spot with the 4099 mounting gear, but then if that didn't happen I'd experiment with what you mentioned since I have an H clamp as well. Glad it's working for you!
