Hello Fred,

I have two G300v21 boards, which are similar to the G300D, but wihtout the DSP (as far as I understand). The quality of PCB, parts, and overall assemply seems very good for the price IMO. I've not done intensive listening, but my immediate impression is that they sound really good, powerful and clean, and with very low noise floor.

With regards to the DSP, I think that Sinewave is using SigmaDSP and this seems to require a quite expensive USB device in order to configure the board. But perhaps you know more about this than I do?

Soren

Hi Soren ,

Yes it's SigmaDSP , but expensive is a relative word, it's about 200 Euro. I don't have it but I played around with the software. It was pretty cool. Anyway I am still looking for a 3 (2*) or 6 channel class d amp.

Yes

Yes

200 Euro is almost the price for a Behringer NU1000DSP, so I consider this expensive. Didn't know that getting to the DSP in a Sinewave DSP amp would be that expensive:eek:
 
Hello all, Someone know if it possible to have (probably by using SigmaStudio or others tools) real time control on crossovers frequency, parametric EQ and volume by a serial communication canal on G300DD ? Migmha

Mickel, we upload block digram picture here, you can real time control it by Sigma Studio software through USBI downloader or you can use one MCU real time control it by I2C with same port.

I2S digital format is 24bit slave mode, DSP is master.

400K G300DD AND 600K G300DD

Our latest version of G300DD have finished , pass all of our test now, paste pictures here .

DSP+TAS5630+Wide Range SMPS all in one

Main class D chip is TAS5630, it can works up to 600Khz PWM frequency,600Khz idle load heat consumption higher than 400Khz, but sound quality excellent.
Named G300DDK6 and G300DDK4

we have compared lots of other chip modules, TAS5630 sound excellent, suit for studio and home audio, high clear bass vigorous.

we have preamp board which support 24bit USB/optical/coaxial input and have I2S slave mode interface .especially it support Asynchronous Sample Rate Converter and this chip have -144dB THD+N and 144dB dynamic range.

It have complete protection function, works more stable.
