Easy would be the old school latching relay makes a nifty kachunk when it works, but not too sure what's available in 600w
if it was me id buy a latching switch, remove the momentary one and take the button off it, and hack the latching one in, in its place.. likely using a fair amount of epoxy in the process.
although the "kachunk" sounds good 🙂
Sorry for the late reply:
3-pin connector - Molex 22-01-2035

Crimp-on socket - Molex 538-08-50-0032

I crimped these on using a pair of small needle nose pliers instead of the specialized crimping tool. You’ll need one per each wire (6 total). I bought spares in case I messed up the crimping.
Thanks Rich. I'm looking forward to trying this amp out on 2-ch full differential, and do also have a 4-ch speaker system to try the SE configuration. I'll probably end up having my daughter order a second board, though.
I'll be using them in 2+1 mode. If you read through the EVM manual, the 4+0 mode is described. Just note that it accepts single ended connections in this mode.
BTL for the sub and Se for the mid/tweeter. One channel not used.
Plug in filters. HP for the mid/tweeter, BP for the sub.
Had to use TPA3255 because of 40V supply.
My own board though...a little off topic, sorry.

Depending on your power needs the 3255 in SE will do some 40ish watts into 8 ohms on a 48 V rail? At which point, you've got to ask, "how much power do I really need?"
(I think, don't quote me)
Boards-wise, at this price it's really really hard to justify anything else. None of the Chinese implementations are as nicely equipped, and hardly cheaper. And the 325x series is, as mentioned elsewhere, a notable step up on anyone else in monolithic class-D amplifiers.

I think you have a point.
Re😛ower. 🙂
I agree, for the price, especially with reduction.
I can buy with confidence.

looks like promo is still active as there is a new TPA3255 "digital equivalent" available: TAS5634

I've had my eyes on this for the last month. PCM-->PWM-->--Filter-->Speaker.
The discussion about PSVC (power supply volume control) is interesting.
$249, though.

Nice amplification solution for an all digital system. I love my vinyl too much to go that route.
Is anyone aware of big name commercial AV equipment manufacturers who are using TI's Class D technologies? I have to believe they sell a lot of their Class D ICs to notable, high volume manufacturers to keep investing in this market.

ha.. i was looking for an all digital amp with decent power output before settling on the 3255.. couldnt find anything decent. all my sources are digital.
having said that, ive now got 2x 3255 evm boards.. i could only have purchased one of these for the cash. plus, reading the setup guide.. it seems rather more involved to configure, and its not clear if it could be used easily in a daily-use system.

Me too. Thus I'll tweak this and that to get some more TPA3255 EVM boards at the discount.
Best regards!
@Kay - may I ask what you plan to do in terms of tweaking? - please make sure to keep us posted.
