we are making new simple version of this amp which customer can adjust crossover and EQ with computer and download easier with USB port on amp ,most of other audio functions fixed in DSP. Maybe some customers like this.
To get full benefit of DSP for crossover implementation, the user needs to be able to upload acoustic FR measurement, as with most loudspeaker design software, and see final response.
See here for an example.
Software can be downloaded and evaluated here.
we found most of customer from diyaudio like sigma file debuging and try all audio parameter themselves , of course lots of audiophile like enjoy fixed audio parameter amp .
so we decide produce two version of this type amp, one for expert and open sigma files, one for audiophile with fixed parameter .
we have some USBI downloader here, if necessary ,tell us.

I don't understand this statement. Can you please clarify?
I don't understand this statement. Can you please clarify?
oh! usbi downloader from ADI company,it can debug sigma files realtime and download sigma files to DSP anytime.
G230V1.3 UPLOAD

pics here:
We have revised our G230V1.2 board, better sound,better performance.it is our excellent module, it can be used as 4x300w/4ohm or 2x600w/2ohm or 2x300w/4ohm+1x600w/2ohm, even it can be set as 8channel module, only one extra half main voltage board need.
it have mass manufacture. works well.we apply it in High level sound system. some friends assemble it as 8channel PA amplifier. some assemble it on Hi-Fi audio system. 2ch/4ch/8ch/2.1mode /5.1mode

Wow nice board that is interesting. I'm sorry since I wasn't sure where this was going.
I decided to buy other t-amps..
I'm still interested tho.. What would be the price of this board?
how much to have it in 8ch.. do you loose sound quality when going 8ch?
sound well , it is pro amplifier design, sample order here.

two chip block comparison:
Yes but like Sunshines said, we want less conversions. If you make a complete amp with the TAS5631B direct PWM like what TACT does with their super expensive amps then I'm sure you'll be selling many. Nobody else in the market has a TAS5631B full amp. Please make it or at least make some for us

DEXTER sell it now, you can search their board, we have developed some these amp in 2007 only power stage is tas5261 , any friend like it, we can manufacture and wholesale it for you.

Is it possible to run the G33D all in stereo mode? The spec shows 2.1 and 3 way only. I don't use a sub and any power going to the sub while the stereo out is running 75W per ch only seems like a waste. Please let me know. Thanks.
A suggestion for low cost 4 ways (or multichannel) and even bridgeable Class-D amplifier chip:
MAX13301
...and it integrates I2C interface too !
Hope that inspires !
MAX13301
An externally hosted image should be here but it was not working when we last tested it.

T2100A/T2150A&T2100D/T2150D amp module finish!
We developed new module use NXP tda8920cth and tda8950th .pass our test now, works well.
T2100A 2x100w/4ohm TDA8920CTH+SMPS
T2150A 2x150w/4ohm TDA8950TH+SMPS
&
T2100D 2x100w/4ohm TDA8920CTH+SMPS+DSP
T2150D 2x100w/4ohm TDA8920CTH+SMPS+DSP
Test:
1. full load shorted protect passed,
2. no load full signal out direct shorted protect passed, full signal cap shorted output and inductor shorted output passed.
3.tempreture increase over current protect passed.
4.48hours half load burning passed.
5.pulse signal test passed.
6.square wave test passed.
We developed new series integrated DSP with tda class D chip(T2100D/T2150D), because we found no analog limiter performance better than dsp limiter,it can be works well with larger dynamic range, some of our customer assemble it in live show system, mic and cd signal mixed, amp burnt or tweeter burnt in worst case, but when add DSP unit, all fine.

DMP1250 BI-AMP DEBUGGING!
We developed new version dsp processing active power amp modules, according to our customer reply, we set USB control port on panel, so customers can set General Parameters self .
DSP Unit Features:
1. 1 balance analog input and analog output.
2. 1 digital audio (AES3) input and digital output.
3. 4 analog output.
4. Support PEQ/xover/delay/limiter/gain setting.
5. support USB real time communication between computer and module.
We use advanced DSP from ADI, 172MHz core frequency,support 170ms digital audio delay,support AES digital audio asynchronous sample rate converters.
Compared with DM series active modules, it is hi-end version, debugging now.
