Issss eeet safe?

Hi,

Brand new to the site and hoping someone can solve a mystery for me.

Over the past several decades, I've owned just about ever good combo amp under the sun. Recently though, I've been really turned on by a lot of the new low wattage heads that have become available. In the past couple of months, somehow my house has become full of them.

Having not used heads and cabs in the past, I never had to think about things like impedance. I am smart enough to get the basics right. Most of these heads and their associated cabs are 16 ohms. No problems there.

I have an issue though - space. I'm totally running out of it.

So, I happened to notice that most of the cabs I have have multiple 16 ohm inputs. Seemed logical that I could plug head a into one input and head b into the other.

Both heads would never be turned on at the same time.

But I did some reading and found that the extra inputs really seem to actually be outputs - so you can run a second cab.

So I haven't tried this yet, fearing damage to one of the heads.

Can I do this? In the imortal words of Zell, "Is it safe?"

Thanks,

Greg

Is it safe?
Is it smart?
Personally, I would not attempt it as the one amp may be trying to reverse drive the other amps output transformer.
Even though only one amp at a time is turned on.
Unless the cab speakers are split.
Like mono/ stereo.

I was thinking the same but wanted to confirm. These area all single speaker cabs so no stereo option.

Thanks,

That's a bad idea, because the output transformer of the non-operational amp would still be connected. It will take some of the power, affect the tone and possibly get damaged - Pete.

As above, unless... If any of your cabs offer stereo operation. That is, the two amps won't be sharing the same speaker/s. You could even wire some cabs up this way if you wanted too.
