Jag_Bassist Posted December 16, 2012 Share Posted December 16, 2012 hi guys, i have a Tc electronic RH450 amp head which i am currently using with the RS410 cabinet. the head can handle anything above 4 ohms and the rs410 is 8 ohms. no problem there. im looking to add my other cabinet as well ( a custom made 4x12 cabinet) which is 4 ohms. would this be ok to run? ive never been to sure on ohm ratings.

charic Posted December 16, 2012 Share Posted December 16, 2012 The rh450 will actually run down to 2ohms iirc Quote Link to comment Share on other sites More sharing options...
Jag_Bassist Posted December 16, 2012 Author Share Posted December 16, 2012 oh right can it? the back of it says minimum 4ohms Quote Link to comment Share on other sites More sharing options...
chris_b Posted December 16, 2012 Share Posted December 16, 2012 Look at the TC RH450 User Manual. [b] [url="http://www.tcelectronic.com/media/914735/tc_electronic_bass_amp_power_rating___active_power_management.pdf"]RH450 Power Rating & Active Power Management [/url][/b] on the very last page there is a table which lists the RH450 as Min Load 2.66R. That means you can either run 3 x 8 ohm cabs, which is 2.66 ohms or 1 x 8 ohm cab and 1 x 4 ohm cab, which is the same. Quote Link to comment Share on other sites More sharing options...

[/quote] That was TC's little game, where they said you could run 3 of their cabs but they pretended you could only run 2 of anyone else's cabs. They have now come clean and added the correct info into the manual. Quote Link to comment Share on other sites More sharing options...
