It is just a pass through for the one not connected.but how can it be an input and output at the same time? How do you switch from input to output?

Just got one of these, the function of the 3.5 socket on the back is absolutely not clear to me. Is it an input or an output? The manual refers to it as an "output interface" but that makes no sense to me, why you'd want to output from an amp to something else. Versus an auxiliary input which seems like it would be handy from time to time. Sound quality is good with the supplied 32v/5a supply, sounds considerably louder than the a04 amp.

II swapped the cable on the speaker and yes, the unbalanced sound still exists. This time the lower volume on the right goes to the left.If you swap speaker outputs, does it switch sides for lower speaker?
Other troubleshooting steps;
change amp, see if problem exists. Change source see if problem exists.
Check speaker (buy dats v3, well worth it).
What do u mean by power supply noisier? Buzzing or coil whine from the external power brick, seems pretty strangeOh, so you could use that to send signal out to a subwoofer? That is handy i so. The manual sure does NOT make that clear.
I was also amused to see that the a07 also has socketed op-amps. They make a big deal about that in the a04 promo copy, but don't in copy for the a07. I thought the op-amps would be soldered in.
I bought some OPA2134PA op-amp's directly from TI, but they made my power supply noisier with the a04. Going to try again with a different power supply and see if I get same result. Aiyima had told me the 2134 amps would be a good match to replace the stock ones...

I've the A07 and swapped several opamps in there to try for fun, never had any problems, and like the sound of the OPA2134PA the most tbh. It sounds quite a lot warmer than the NE5532 or LM4562NA.

Hello! Could someone link me a power brick that won't burn down house for this amp? Aliexpress if possible but european stores or amazons work too!
Also, should I get A07 with NE5532? Is that good?

70 bucks on aliexpress, bit much for me. Would something like this work? https://www.aliexpress.com/item/32773452243.html? And what else would I have to order with it to work with a07? some cables?I bought a MeanWell GSM220A-48 and it works great. I ordered it using my partner's VAT number lol.
On that note my amplifier is working pretty well for a passive sub. fairly low noise and thermals are good.

Here are my measurements:I don't have a direct measurement but the spec sheet for the chip indicates idle is about 2.5w. I have several class AB amps as well and the difference in heat is HUGE. Even my Crown XLS1500 uses approx 35w at idle, even though it is class D (probably the reason is the DSP which would always draw power, even at idle). The Crown used to be my "summer" amplifier because it was so cool and the Aiyima a07 now makes it look hot!
(3.0W when the amp is turned off)
The power supply included with the amplifier does not turn off. If the same amp were installed in a bigger case and the power switch was positioned to turn power off to the power supply there would be the expected 0 current draw when turned off.
