hi everyone. does anyone else use a pre/poweramp set up to play guitar? im thinking of getting the ART pro SLA2 power amp to run my preamps into then to my 4x12. the art pro website says it runs 280w per channel @ 4 Ohms. OR run in bridged mono mode for 560w into a single 8 Ohm load.
my concern is that i dont always get to choose what 4x12 cab i use when playing live.
1 - so if i use a 4 Ohm cab can i run the sla2 in normal 4 ohm 280w per channel mode but just connect 1 output to the cab and just simply turn the volume off on the unused channel?
2 - what do i do if i have a 16 Ohm cab?
3 - can i use the SLA2 in bridged mono 560w mode and run it into a cab that either 4 Ohms OR 16 Ohms? what would the outcome be?
thanks for any help folks.
Use one side of the amp and don't worry about resistance unless it's under two ohms.
