DSP
Hi James,
We are developing the DSP using a modular platform so that we can use it in our own systems and as a stand alone speaker management system.
We have two versions, one using the :
TMS320C6748 | C674x DSP | C6000 DSP | Description & parametrics chip
and the other using the:
http://www.ti.com/lit/ds/symlink/tms320c6678.pdf chip.
Moores law means chips are always being upgraded so our boards allow for new chips to be used as they come on stream.
The boards all have room for up to 4 DSP chips so they can be bought in single, double or quad chip layout.
Even the single chip version is a beast....Easily handing 4 way stereo (8 assignable channels) FIR and or IIR crossovers / speaker Eq / room measurement & correction / speaker protection plus some other features that we are keeping up our sleeve at the moment....😉
Our DSP is designed for recording studio mixing / mastering & live sound and the user interface will be similar to the industry standard which is
of course Fab Filter, check out their lovely UI here: in....FabFilter Pro-Q 2 - Equalizer Plug-In
Our DSP is at the other end of the market from Mini DSP both in performance and price, but we will release some versions bundled with our loudspeaker kits which will offer unbeatable price / performance.....Once the whole system is ready we will publish details on our website.
All the best
Derek.

Thanks Derek,
I was looking at systems like the "Ground Sound' or the developing 'Nadja', but will wait awhile - a 'dumbed-down' version (especially for people like me!) might have a significant market ....

DSP with no phase issues....
Hi James,
I think it will be worth waiting for....We are developing a unique filter / Eq implementation which allows control / manipulation of the frequency domain with absolutely no affect on phase.
Some so called "phase linear" filters or Eq plugins actually "bend" ( distort) the phase 360 degrees and claim this is this phase linear....Its not.
It has a time / jitter side effect which is very audible but difficult to measure....Until you are looking for it!
All versions of our DSP will include this feature and have enough power to handle up to 4 way FIR crossovers and room Eq.
The studio / Pro versions will add more features and power.
Things are taking longer than we expected as there is a lot of ground breaking tech which has to be documented carefully in order to identify and lodge different aspects of the IP for patent applications.
All the best
Derek.

Hi Derek !
On your tests with real LA9 &16 does the amplitude frequency response became with many peaks and depressions ,with a decrease or increase the number of drivers in the array LA ? (Due to the non-ideality of the distance between the drivers at different frequencies and interference between drivers). Whether strongly narrows the vertical directivity diagram (! to absolutely no need to narrow)?

I'm glad you said "some":
It looks like FabFilter Pro Q2 does linear phase quite well as measured in the above loop back test. I bet PLParEQ does an equally good job.

Fab Filter
Hi Wesayso,
Fab Filter Pro Eq is the most popular studio Eq Plugin, and rightly so!
I have used it for a few years and recommended it many times on this site.
A budget laptop with JRiver and Fab filter feeding a mid range AV amp makes a killer combination.
Especially for guys like us running full range line arrays, good Eq is essential to maintain the performance capability of a well designed array.
As good as Fab Filter is there is still room for improvement....We have made significant progress and are very happy in side by side comparisons😉
The other goals are to reduce the cost significantly, reduce the size / power consumption and simplify the user interface / experience.
Ie at the moment one needs a lap top / PC, operating system, media center type program to implement crossovers and order the music, then add your Fab Filter plugin(s) and then on to feed your amplification and speakers.
This is great for all us geeks(!) but in the real world very few people are prepared to run this type of rig....
Our goal is to condense all this down into a one box solution.
A media hub which WiSA 's out the signal to the on wall active speakers.
No speaker cables, no USB cables no interconnects!
The hub is modular and will be available with a wide range of connectivity options (including cables for the geeks!) to avoid paying for features you don't need.
As the hub includes our DSP, a WiSA transmitter board and a modified Raspberry Pi its firmware is up-gradable and connects to external NAS storage or servers as well as the cloud.
The cost of this one box box solution will be lower than the total cost of all the hardware and software currently required to do the job.
Our performance advantage is significant, the cool form factor and user experience are superb....All in all it moves the game on big time.
All the best
Derek.

Not sure of the question!
Hi Nickolay,
Sorry, I am not sure I understand exactly what you are asking?
You mention "peaks & dips" and "directivity" and "driver spacing" ....
I am guessing but most of the questions I get usually relate to:
(1) Comb filtering / centre to centre driver spacing.
(2) Eq'ing to control frequency response.
(3) Driver to listener distance.
(4) Room interface effects.
Please check back in this thread and various other threads I have explained in detail why on wall line arrays using BMR's are unique and in my view, superior to any other solution.
In summary:
On wall BMR line arrays with good Eq avoids the above altogether and / or enables effective solutions to be implemented easily and at low cost.
Hope this helps and all the best
Derek.

Ultimate tool box...
Well said Byrtt!
It will be a tool box....One you can buy with your choice of tools inside....
From minimal "lite" all the way to "serious Pro".
We are behind schedule due to the time it takes to identify all the IP and lodge the patents, but rest assured something cool is coming in 2016!
Cheers
Derek.

Hi Derek, it sounds like you have lots going on but do you have an idea when the BMR DIY speaker kits will be available ?
Hi Derek !
Thank you !
First of all I mean different frequency responce along array height ? Is it necessary for it FINE (precision) correction ? Or FR is more or less stable on the desired vertical listening zone , without precision correction ?

Hi Nickolay,
The frequency response of a wall mounted line array of BMR's is very even in both vertical and horizontal axis.
With my 4.5 inch BMR's the power response is easily Eq'd to within plus / minus 2 dB over a 150 degree (plus minus 75 degrees) arc.
I hope this answers your question?
Cheers

+-75 degres with +-2db uneven power frequency response ON VERIICAL(?) and horozontal arc ?

Vertical and horizontal axis
Yes,
The vertical response of a true line array (75% or more floor to ceiling height) of BMR's is superb, very even once you move to a listening distance of 1 meter or greater.
At a 3 meter listening distance the LA 16 vertical response averages within 0.7dB measured at 20 different heights over its 1,840mm height.
To qualify as a line array the line must be at least as tall as 75% of the floor to ceiling height of the room its in.
Anything less and the "array" starts to act more as a point source in many performance aspects.
I hope this answers your question?

(2) A 22 liter sealed box with a single BMR & a 15 inch bass driver.
(3) A 30 liter sealed box 9 BMR array.
(4) A 10 liter sealed box sub with a 10 inch driver.

Hey Derek,
Very well thank you & I hope you & your family are all good too, I expect there is a pre Christmas buzz starting in your household around this time 🙂
I was really hoping to get up last month but I had a difficult job on that over ran into my November job, I'm now hoping to find a day around mid December that would suit you, I am so looking forward to hearing these systems.
Would anything be "purchaseable" at this point 😀
Kind regards
Jason
Mid December
Hi Jason,
Yup, the kids are already building their Christmas lists and watching "The Polar Express" to get in the spirit...!
Mid December is good and by then I will have some kit available to buy.... I've got to pay for the kids Christmas list!!😉
