Hi all, I just received this TAS5613 amplifier from Aliexpress today and thought I´ll share my first thought on it, as there aren´t many reviews about it.
First thoughts:
1) Something was rattling inside the case, so opened it and the heatsink was loose. It also had no to little thermal compound.
2) There are two models of this amp, "Blue/Green" PCB´s. One uses the csr8635 bluetooth module and the other is1684s. I ordered the "New"? model with the csr8635 because you can change name, eq settings etc, but got the older one
anyway...
3) The amp look nice, fairly small case (160x100x36) not counting the antenna, plugs etc. The amp can be driven from 16-32v, but was recommended to run at 36v (datasheet), but a 32v 6A wall adapter which will give you plenty of power (recommended from seller)
4) The PCB and components screams cheap. I´m no an expert, but it has cheap nichicons knockoffs, crusty pots and loose filter chokes.
After using the amp:
1) Small on pop, and the relay makes noise when it switches between bluetooth and the RCA input in the back.
2) Huge noise floor of 1,6vpp at a carrier frequency of 460 kHz (Can´t remember exactly, will update when I take new readings)
3) Has a weird Bass, Treble, Volume settup. The master volume is way to low, the bass only adjust the subwoofer volume leven, not frequency (which I prefer). The treble is only adjusting a high pass filter. Im going to try to increase the gain of the master volume and decrease the bass. Hopefully this will make this usable, as it´s currently only bass from the sub and nothing else at full throttle.
4) The filter chokes gets warm but touchable, and heatsink a little warm after 15 min.
5) No noise from Bluetooth module, but it´s hard to tell because of the general noise.
6) Got over-current/ clipping feature. Turned the subwoofer channel off when I played to loud.
7) Ok sound, works for medium to high volumes, but board needs to be adjusted for final thoughts.
That´s all I have to say for now. Maybe there are some other people out there who got one of these and know if there is a way to remove the noise? Would love to modify it to work properly without any noise, on pop and have a moderate gain settings on the preamps.
Any help appreciated.
