Digital Power amp , Switch mode Supply.

Does anyone know if you can run a dighital power amp , with a switch mode supply , without speakers connected ?

I know you can with old power transistors , and you should not with valves .

Yep, no problem.

Hi BassBunny, do you think that l should put a 8ohm 50w resistor , with a heat sink, across the position the speaker was,  as a safeguard ?

I have asked Fender this , weeks ago , but no reply .

No need. I presume it's a Class D amp? Fender Rumble? It will be fine run without speakers connected.

Hi BassBunny,

Just to let you know , I will be removing the entire module from a Rumble 40 Studio , putting it into some form of small box / case , and feeding the effect send from it into my Warwick LWA1000 .

The 40 studio has all my needs to play live , but I did not want to carry an extra speaker cab , hence the original question .

Thanks for all the help .

Someone may ask , why not get the Rumble 800 .......well the 800 is actually 400 on its own , you need a 8ohm 400W extension cab to get the full 800W out of it .

I will stick to my Warwick LWA1000 and two 2x10 Markbass cabs . VERY mobile , and use the Rumble Module as a preamp.

Pete.
