Hi Everyone,

I'm just starting out with my slippery slope into higher quality audioworld and I've stumbled on my first steps already. To replace my TV audio finally, I just received my hopefully new system with 2.1 in mind. As I know very little of this topic, I tried to start as simple as possible and get a good and cost efficient setup and ended with 2xTruth B2031A + Nekkst K10S subwoofer.

So the problem I have is that when I turn on my sub the monitors seemingly turn off and I only hear sound from the sub. It's almost sounds like my neighbour had their bass booming.

I have connected monitors with XLR male to sub XLR output male/female and my sub is connected from line out to micro jack in TV (headphones). Monitors do work when sub is turned off however.

What could be wrong here? I was under the impression that no amplifier would be needed here but am I wrong? I also tried to change audio source to my phone but it seems to have no effect. I feel like such a noob so any help here would be really appreciated.

Thanks in advance!

(Ticketing system is broken)
I have extremely low output on my Truth B2092A and need a circuit diagram to replace the primary capacitors, resistors and transistors on the board. The transistors part numbers are either worn illegibly or missing, and some of the ceramic resistors P/Ns I can no longer get the whitepapers for. I've had this sub since new (2007) and last year built my entire recording studio desk around this sub and its dimensions - I'd rather not just scrap it. Either that or if I can get a replacement board, but finding one is getting increasingly difficult.
