because rear panel no room for toslink hole and coaxial hole, so you can select toslink or coaxial. thanks!
DM1250 DSP PROCESS BI-AMP
Holiday back, Happ New Year!
take some dm1250 pictures just ago.upload here.
specs have list earlier thread.
1. DM 1250 1000W/4ohm+ 250W/8ohm .
2. DSP process most of audio functions like limiter/crossover/EQ adjustment .
3. 110v or 230v ac supply 50 or 60 Hz
4. 2 analog input, Mic or line selected by key
5. 2 analog output,+4dBu
6. All aluminum heatsink as plate panel,8mm thickness in this batch

adi dsp programming
IDC10 socket for ADI USBI downloader, ADI USBI actual port pin number is 10, in AN1006 note described as IDC14.
you can program it with sigma software,full function programming for DSP and open access environment. we find some customer development PC software with such DSP only have few function and mcu controller works condition not good as idea.
Nice looking units!
How one goes about programming the built-in DSP?

New version DM4000D will finish next month
Some customers ordered DM4000D active subwoofer amplifier module, we have to revise original version structure .
1.Add variable fan cooling system on board,so transformer and electric parts can benefit from this .original version heat dissipation depend on rear aluminum panel. find transformer temperature higher full loader.
2.Add air vent on panel,add closed lid, improve air duct.
3.two balance input two balance output(analog)
4.DSP processing,Sigma files support
5.Gain and cut frequency adjustment
6.Dimensions:400mm(H)x300mm(W)x70mm(H)
7.Frequency Response:20Hz -150Hz +/-0.5dB
8.Rated Power:4000W/40hm
if any good idea, pls tell us.

it is good idea, we developed special circuit for this,works well. if interest, you can order some for testing.
I thougth this is a diy forum
My amplifier is already build, but I wanted to eliminate the *speaker-plop*.
Maybe I will try the TL7712 Reset circuit.
If you would like to share your reset circuit, a pm is very appreciated.
Kind regards,
max

Our engineer tell us just ago, maybe good method ,you can try it.

I am planning to buy two Sinewave G330V21 amps for a DSP based active crossover 2 way stereo speakers:
Wholesale TAS5630 HIGH POWER Hi Fi CLASS D AMPLIFIER LASTEST VERSION HIGH STABLE HIGH DISCOUNT!
based on this TAS5630 module:
Wholesale TAS5630 AND SMPS AII IN ONE BOARD
Looks like a very cost effective solution. I am not a diyer, but I want to build my definitive audio system and I am very interested in top quality. I would be very interested in having some impression on it in terms of quality/taste from someone who tested it or the board it is based on. Has anybody compared it to other modules e.g. ICEPower, ClassDaudio, Hypex etc?
One more technical question. The amp's input sensitivity is rated at 0dB/100kΩ. Would it interface well with my Minidsp 2x8 board, whose maximum output is rated at 2Vrms (8 dBu) in unbalanced mode?
Thanks in advance for your help

Dear authlxl,
when you say at point 10:
10.DSP or Analog preamp stage selected.
do you mean that this amp will allow for full digital input (I2S) from dsp, so no A/D conversion is needed but just D/A after amplification?
This would be very interesting to me and would make me opt for this solution instead of the genius 300V21.
Is it based on TAS5630 as well?
When will it be available?
Since 2x500 watts is quite overkill for me, are you planning to provide a lower power module anytime?
Thanks
Oreste
oh! very sorry, I mean we have two type preamp board, one preamp process audio signal with analog circuit, the other process it with DSP . all of them output are analog .we will paste more pictures here next weekend.
Thanks
I decided to buy 2 Genius300V21 for my dsp active speaker setup. The Input sensitivity of the amps is rated at 0dB/100kΩ. I do not understand what this means in terms of interfacing it with minidsp 2x8, whose maximum RCA output is 2Vrms (8 dBu) in unbalanced mode. Can anybody help me?
Is the aliexpress site:
Wholesale TAS5630 HIGH POWER Hi Fi CLASS D AMPLIFIER LASTEST VERSION HIGH STABLE HIGH DISCOUNT!
the official authlxl web shop?
Is there any special discount for diyaudio members? I am buying 2 amps.
