Hi looking forward to receiving mine I ordered today. I bought a 24V/12A linear regulated power supply. The one it comes with switching and only 6.7A. Should be much better. Two questions: What is Line level sub out crossover frequency and slope please. Any high pass for class D internal amp when you use the sub or still full range? I dont like 24V input connector, does not support high current. If easy I want to solder wire from my power supply direct to the board. Much better. I know it probably will void the warranty but Im a good technician. Do you have a picture inside to see the board? Thank you.

Hi, thank you for your message.  We don't have the sinde cuircuit picture for SMSL AD18.  In your case, to solder wire from your power supply direct to the board would probaly have quality warranty issue.  Altough we are not suggest you to diy the product, we will help you to follow up with your product quality issue.  Thanks  Shenzhenaudio
