Can you leave 2 speaker cables (jacks) in the back of an amp with only one connected to a speaker?

Hi

I have an SVt3pro and a wireless system in a rack flightcase and ive got power supplys / 4 way and LED transformer also in the back. I've just bought a vented rack panel to put on the back and keep the multiple leads neat an in place. The rack panel has holes for leads to come through and the idea was that I would just leave the 2 speaker leads plugged in to the back and poke them through the holes and use one or both as I saw fit as it would be a pain to keep unscrewing the back off and kind of defeat the purpose.

Is it okay to leave one unconnected lead in the back of the amp? or will it cause a change in output getting to the connected speaker cabinet? Can;t work out if it would just change when you have it connected up.

Cheers

Is it just parallel jacks with switching impedance?

Really, the answer is no if its jacks, because you have a live end dangling about where it can short.

Like Mr F says, you can't do it with jacks, it's not safe. You could use a lead wired to a jack socket mounted on the hole in the back panel, like a typical FX rack patchbay.

Are they jacks or speakons? The speakon is pretty much self enclosed.

You could do this with a jack plug PROVIDED you make sure it's insulated eg. put four condoms over it.

Seriously, it is OK if it's insulated. Even a few turns of electricians insulating tape would be fine and prevent a short circuit.

Perhaps female to female jack connector might be a viable option? At least the conductors would be enclosed.

Quick option: Just cover the exposed jack with gaffa / electrical tape.

More permanent (and safer): connect to jack sockets in the back of the rack. then use the sockets you need.

Why do you want to seal up the back of the rack?

There is no point!
