Connect amp to a cabinet in another room?

[DocSauerkraut]

Hi!

How can i connect my amp to a cabinet that is placed in another room? There will be approx. 15-20 m distance between amp and cabinet.

I suppose i should do this via a XLR cable? But do i need DI boxes for this or will adapters 1/4" -> XLR work?

Long speaker cable? That's how I've done it in the past.

I've had no issues with even 100ft speaker cable. The main thing you want to avoid is long instrument cable runs.

Either a long speaker cable run or one of these:

The SGI will require the head to be in the live room. I've got one and it's killer!

Long jack-jack speaker cable, no DI boxes or XLR's involved.

Just make sure you use a speaker cable of sufficient gauge. 12ga (≈ 2mm) is sufficient for virtually any amp to speaker application. I wouldn't go thinner than 14ga.

Yeah, my 100ft speaker cable is insanely heavy gauge, not recalling off the top of my head...

I have literally cut the ends off of orange power extension cables and soldered 1/4" phono plugs on the end. They're dirt cheap and rated for far more power than an amp will ever push through.

Most cheap orange cables are 14ga which is probably more than sufficient. However, my attitude is that as much as you can completely eliminate potential issues from the distance you should when dealing with tube amps since cable impedance increases with distance and that can affect tone and increase the load on the head.

Great!
Thanks for all the comments.

This is genius. I need to try it just for shits and giggles.
