Hello guys, i recently buyed one amp with power supply from sure-hifi (ebay) and i saw there was a warning there (DO NOT power the amplifier board when there's signal input, or the chip will be burnt out. It's suggested to plug RCA jack first, stop signal input and then power the amplifier board. Finally, Begin signal input after 1 second) dose anyone had this problem? this sounds absurd to me.That means, the amp is very unstable.

Don't order TI TAS5630, its sound quality is not good. I've ordered 4 IRS2092 2x250W boards and sound quality is much better. It uses dual +/- power supply and at high voltage values (+-60V) with low resident noise and lower THD+N (only 0.007% at 100W). The sound quality is very very good. I use a 2KW toroidal transformer and two Nichicon 100.000uF capacitors in power supply stage.

Good suggestions are appreciated, Many thanks!
But cost of I2S to PWM are probably cheaper than a good DAC. I once owned the panasonix SA-XR55 (don't no which TAS chip). Analouge input was bad sounding, but digital spdif was really good.

latest Version TAS5630B board completed, it is G300V33 series, G300V33BTL is 2channel module, G300V33PBT is mono channel module,

Very stable now, shorted output together anytime no problems.

Dynamic limiter support,

DCP /OCP/ UVP/OTP protections, even POWER LEVEL control system added, this function can make the module RMS power about 400W total.so the chip can run under safe conditions.

Key benefits
Backup DC supply system, suit for solar or car system application.
A wide set of features for plug and play implementation into applications such as active speakers or proaudiosystem.
Black-box design, module have good heat dissipation and better EMC performance.
Advanced protected function against short circuits, overload and overheating and includes on-board fuses and EMI filtering that provide a CE and FCC pre-approved design.

Key Specifications
.POWER OUT:
G300v33BTL 2200W/ 4Ω@1%THD+N /2 BTL MODE
G300v33PBT 1X350W /2 Ω @ 1% THD+N /1PBTL MODE
.FREQUENCY RESPONSE: THD+N ≤0.05% / 20-20KHz / <1dB/1W

.INPUT SENSITIVITY: 0dBV(1Vrms/BAL input)

.S/N: 98dB(AES-17/A-weight)

.POWER SUPPLY: 110VAC OR 220VAC 50 OR 60Hz

.AUXILIARY POWER: +/-14V @ 500MA max

.DIMENSIONS: 160MM(length)*80(width)*52mm(height)

.NET WEIGHT: 0.46Kg


Key Features

Balance input and balance output design, Hi-Fi sound design
Multilayer PCB and thickness copper route
Dynamic limiter inside, suit for proaudio system
Black-box design, high power small size
Multi current protection and auto reset system
Clip signal indicator
channel PWM running status have led indictor
Suitable for CE approved designs
Proaudio system To Hi-Fi design
Backup DC supply system

SYSTEM TESTING

PROTECTION TESTING
Output shorted testing passed
Shorted output wire while half loader running , , good protection performance.
No loader and amp running . 1vrms and 1khz signal added, shorted output, protect well.
Over load testing passed
Add 1khz signal and connect 2ohm loader, increase the input gain , if loader power over 400W, SMPSOCP protect will happen, it isconstantprotection.
AP testing below

Tas56XX is TI advanced products, circuits better than others single chip class D amp,sound well, even it have bugs sometime, Friends must pay more time and money in it then can use these chip to run well,some time it is complex to make these things perfectly.

From 2007, Sinewave engineers start to develop TAS56XX chip supported class d amplifier.we burnt hundreds of this series chip and finally we make this series amp more and more stable, uploaded modules here are the latest version, we think it is the best solution of Proaudio to Hi-Fi .

Sinewave Electronics Co.ltd have factory and high level audio laboratory.we have rich experiences in class D pro amplifier, especially in CLASS D and SMPS all in one amplifier.these amp have widely used in audio and ultral sonic area , products quality better and better now.

We have list some of our products in DIYAUDIO forums, we got lots of member supports here, base on these good ideas and suggestion we have made rapid expansion .

We will try our best to make more high technology products in this area, thanks for more suggestion from the diyaudio member.

Annonce here, we have no chance to service Sure company now, even we know it is China company too.
