I don’t know what make this thing is , I’m not sure the total watt, I think 250 watt total could be more,3 setting low ,med ,high ,”Great pre amp” it took a good radio to slam this thing but I talked skip all over the country on LOW SETTING, like I said I can’t remember the watts it puts out but it did great on low for us base to mobile 60 miles we used a 2510 around 8 - 9 watt to slam it. Have fun
