Well I kind of stumbled across this in the past, but I didn't fiddle with it much to really notice how bad it really was.

I ran the EQ for quite some time in the combined L+R form, and all works fine. The boosts/cuts work as they should.

More recently I started playing with independent left and right EQing. I initially thought there was a time delay issue that was causing most of my problems. This was somewhat confirmed by a Ural staff response. When the EQ is active, it goes through a processor, and this would effectively cause delay. This might be noticeable if you have no EQ for one side but EQ on the other. ....maybe.

Upon further, recent investigation, it has come to my attention that the seperate left and right EQ, if seperate from each other in setting, will not function correctly. In fact it seems so bad that the EQ is almost unusable. The range from full to negative infinity for any EQ band barely does anything. Output changes somewhat but not more than a few dB. When it does change, it seems to screw up the whole frequency response too.

An example:

L+R equal

If you cut everything from 2kHz up, setting everything to negative infinity, all output will be cut on both speakers. They will play up to 2kHz and then no output above that.

L and R not equal, ex. setting L 5dB higher then R.

If I cut everything from 2kHz up on both L and R, I still get all the information playing above 2kHz at nearly full volume, only slightly quieter. It simply doesn't work the same way. The dB scale is way off. The range is not there. You can't boost or cut in any effective manner.

There are some other weird aspects it seems to do, but I simply haven't played with it enough to list out everything in detail.

The simple matter of fact is that the EQ is broken when you run the left and right channels separate from each other. This is a feature I would much like to have, so it has become annoying for me.

Playing with the EQs a little more, they seem to have kind of a summing aspect. The further the L and R EQs are from each other, the more off they get. As I bring both the L and R settings closer to each other for any particular frequency band, the more correct they get. Every frequency band is independent of each other, and the behavior seems to be directly linked to how far apart the L and R EQs are from each other. You can move both up and down independently, and they will sound off relative to their distance apart. Once you put one equal to the other, they are correct for the actual + or - dB location on the EQ, be it zero or negative infinity.

150 views 2 months and no response?

If Ural is not planning to support/expand the Concert CDD (firmware hasn't been touched for a year and half), give it to the people.

Build a SDK for the unit and let the people build and expand the Concert CDD through 3rd party efforts. You essentially have a mini PC with TONS of potential, and you're holding it back through company disinterest after moving on to other projects within the company. Let the public take over where you left off and further develop the software and functionality.

Heck, you may find that some of these 3rd party programs build some really need tools that you may like to implement in some of your other products. ;)

Hi Matt!

I'm new to this forum but i would like to help you. I will try to translate your posts to the public and maybe they will help you or somehow influence the developers. I think that we will solve this problem anyway.
