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.

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 !

3months ago, we start our new project for high power resonant amplifier, which apply in medical equipment, class E +class D topic , engineering prototype amp finished, works well.

Resonant Frequency :1mHz +/-10%
Protection : OTP/OCP/UVP/OVP/
Power out: Continuous /Burst(rms power out)
Loader : Piezoelectric Transducer
Ac power:230v or 110v 50 or 60Hz

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.

we developed new g300 series hi-fi board, integrated tas5630 4ch mode and wide range smps and dsp unit. testing now.

DP2500V3 specification list below
1.2X500W/4OHM/1%THD+N rms power.
2.interleaved PFC stage.
3.DSP preamp unit integrated, dynamic dsp processing (limiter/extend/moise gate).
4.stereo volume adjusted by one pot .
5.BTL MODE can be set by single SPDT switcher.
6.Cycle detection over current protect.
7.OVP/UVP/OTP/OCP/DCP full function protect.
8.auto variable temperature controlling fan cooling sysytem.
9.PFC stage+SMPS+Class D stereo AMP+DSP processing all in one.
10.Dimensions:250mm(L)x132mm(W)x68mm(H)

we have applied this unit to our high power powered mixer.performance good.

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.

Very good!

What is the specification of this one?
