petetexas Posted March 8, 2021 Share Posted March 8, 2021 (edited) 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 . Pete Edited March 8, 2021 by petetexas Quote Link to comment Share on other sites More sharing options...

petetexas Posted March 9, 2021 Author Share Posted March 9, 2021 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 . Pete Quote Link to comment Share on other sites More sharing options...
BassBunny Posted March 9, 2021 Share Posted March 9, 2021 No need. I presume it's a Class D amp? Fender Rumble? It will be fine run without speakers connected. Quote Link to comment Share on other sites More sharing options...
petetexas Posted March 9, 2021 Author Share Posted March 9, 2021 (edited) 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 .

petetexas Posted March 9, 2021 Author Share Posted March 9, 2021 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. Quote Link to comment Share on other sites More sharing options...
