Well if you have a basic PC left you can attach it to Behringer/speakers but controll it with your laptop from your 20 meter via RemoteDesktopProtocol or any soft doing this job !

Free if you have the PC already ! via wifi or with a 20 meter category 5 wire and a basic switch/router (20 euros)

no problem with getting signal 20 meters away, have both balanced and regular option. have problem of how to get signal in computer memory wait for adjusted ammount of time, then play it back, only need pc software (what works on windows) that can do that. i cant find if that kind of software exist, only found some software with minimum delay of 0.1s what is too much for 20 meters.

Hello,
I think foobar has a plugin in the DSP manager that allows for this 'Channel Mixer' in the Delays tab. You can specify for 5.1 sources too iirc.
If you need a pre-configured foobar2000 in useable state let me know and I can upload my install

Hi,
Uh foobar has a buffer, default its set high at around 1500ms IIRC. Try lowering that.

will try to use free vst, with some delay plugins which have adjustable 0-500msec delay, with dry signal turned off i think it should work with asio drivers, if not then i will try foobar with asio and foo record. will post here later if i find solution
