because rear panel no room for toslink hole and coaxial hole, so you can select toslink or coaxial. thanks!

Thanks

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

Nice looking units!
How one goes about programming the built-in DSP?

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.

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.

Thanks so many friends in different country order our G300 board and amp, latest g300v21 have mass manufacture,
it is HI-END amp, sound very good, +50v power supply, full dynamic range working, we set power level limiter ,so it can delivery out full dynamic range music signal.
1.fast reboot circuit added.
2.power limited circuit added
3.Variable fan cooling system added
4.ultra low temperature rising induct added(never over 40C deg)
5.wide range power supply, 100-265vac

Today ,browse our post history, find we have developed tas5630 board long time , we know this chip from TI FAE at 2007,over 5years, 21th version now. it is very hard time to make only one thing excellent.

How do you control the reset pin without a microcontroller? Do you use a special circuit for this? I am very interested in this detail.

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,
