yogilla62: matt_garman is right. Two terminal on both sides reduces cable mess in DIY applications. You can connect power from left or right side. It's nice feature.
Connectioning two power supplies in parallel is not good idea. They must give same volatge in every case (uder load, uder high temperature, ...).

From the datasheet (at the bottom of the page here), it says "AUX Power Supply Output(12V/0.2A) for DSP Pre Amplifier".
edit: Oh, yeah you mean the big ones. Anyway I'll leave my answer here. Some people may not know about the datasheet which is helpful.
Hello guys.
I have a 3e 3255 for my front end and have placed an order for their 3251 3 channel amp so I have my 5 channels of HT .
All the documentation from 3e and nearly all from Ti don't make mention of 8ohm loads. Are there any significant issues with using this 2.1 board with 8ohm speakers?....apart from bit getting all the power obviously.
Thanks

Hi please join the group buy:
Group buy: TPA3251_TPA3255 Amplifier board and ADAU1701 DSP Pre-Amp board

Is the Schneider ABL7RE2405 industrial SMPS suitable for use with TPA3155? I happen to have one NOS. Would it make any difference to dedicated 3e audio smps (apart from obvious - voltage).
ABL7RE2405 - SW PS 24V/5A | Schneider Electric
it can be set to about 28V.

Any one have a complete design for the EAUMT-0260-2-A TPA3255. Im just want it as a power amplifyier and use a preamp for volume and EQ/DSP.
Tipsd for powersuplly aswell.

i have quite a few of them. 2x tpa3251 3x tpa3255 1x tpa3250. Best tpa325* boards from china. the finsihed in melte box tpa3251 amps are now cheap skating and using cheaper than prev caps. e3 after first batch seamed to switch to what i guess is cheaper caps 🙁 but other wise been constant in quality. a cap on 1 or 2 mine had some mess on it, not sure what that seamed to spilled on the pcb. amp works though. i would get them again, current tpa3255 board now has socketed pre amps and though hole caps. they do get warm during use so, don't seal in a peli case like i did with my first 2 amps. doh! i was used to tpa3116 not having so much waste heat! my silly mistake. i use them for PA. so i am pushing them hard for many hours. when i have a rare event.
