Creative T20 Series II speakers standby mode?

[KD2]

For anyone who comes across this - I just spent a couple of hours reverse engineering the circuit in the T40 Series 2 and found an easy mod to make the speakers permanently on (not go to stand-by if silent). I'd expect the same circuit in T20.

Short over collector-emitter of Q2.

Essentially this bypasses the whole sound detection circuit.

First of all, thank you, i have the T40 and i always found the stand-by mode a pain, second, unfortunately i'm not much into soldering, never did it, is possible to have a video on yt with the procedure step by step? It can also be usefull for a lot of people.
From the image above is not much clear what i need to do, short mean connect these two point? How you do this? With a small copper wire?

Any help is appreciated. Thank you.

Found this thread from the steam forum post. This would also prevent the speakers from turning off completely when my PC is shut down right?
I like when the power saving feature does THAT, but not when it goes to sleep while the PC is on, so I'm debating whether to do this mod or try the inaudible sound file method.

It's bypassing the sound detection
Only a guess
But I would think that's different from it detecting
That the pc has shut down
So my guess would be if pc shuts down
Speakers will shutdown too

Try tagging whoever posted the solution
If they're still a forum member
Or tag the people who tried it in this thread

Alternatively try it
Could always undo it if get results you don't want

Yeah, they won't go into standby at all after the mod. I'm not sure how much power it actually saves anyway, nothing in the speakers gets particularly warm on or standby, so it must be pretty minimal.

If it makes any difference, I have Mk1 T20's and its the transformer/power brick that buggs me, if it's plugged in, it stays slightly warm to the touch, even if the speakers are powered off. it has a metal shell and even has little heat fins on it..

But it honestly doesn't use any electricity to speak of... ive done some anaylsis on my household power consumption and ignoring the standing charge, my kettle accounts for about 20% of my weekly electricity use, I like to have 3 or 4 coffees between getting out of bed and lunch time (WFH) and Im really carefull to only have the minimum ammount of water in the kettel for one or 2 cups at a time.

There are aother things that are 'always on' but thats just fridge, freezer and router, realy.

Sorry for this (maybe) stupid question, but i am not an native english speaking person and do not want to destroy my speakers.
I am not sure if i understand this right what i have to to (with my T20 v2):

a) do i have to connect this two points once for a few seconds with an wire (and remove the wire afterwards again)?
b) and if its (a), do i have to do this when the speaker is on electricity or does it also work when i put the power supply off?
(i know, it is mostly a stupid idea to do such stuff when the power is NOT plugged off!)

c) or do i have to connect this two points forever (with an soldering iron)?
d) and if it is (c), do i just need an wire or something like a "10kOhm resistor"?


Maybe someone who did this can show us an picture after this bypass, so we noobs can see what it has to look afterwards.
Or just can answer my questions so i can do this also with my speaker. Thank you in advance.

You need to do this what you stated below and of course with the power unplugged when you work on electric powered devices:-

c) or do i have to connect this two points forever (with an soldering iron)?
d) and if it is (c), do i just need an wire


So use a bit or wire and a bit of solder with a soldering iron to join the two points shown in the image forever. With the power not connected to the speakers when working on it.

Thank you, now it is clear what i have to do.
I opened my speaker, wo this is tiny stuff. I hope it will work, my soldering iron tip is a litte big for this i think.

Hello, I am not a native English speaker, sorry for the translation.
I have the exact opposite problem.
Standby modes stopped working for me. Already at two pieces of T20.
I require standby to be functional!
I assumed some kind of defective capacitor, but it seems that it is not the capacitor (elyt).
Can you advise? Is the T20 scheme available?
Thank you.
