Twincam Posted April 22, 2016 Share Posted April 22, 2016 Markbass amps I've heard can sometimes be picky about where there plugged in. Sensitive protection circuit. Have you tried another socket? Quote Link to comment Share on other sites More sharing options...
Sparky Mark Posted April 22, 2016 Share Posted April 22, 2016 I had the same issue with my F500 when pushing it hard into my Bergantino HT112ER and EX112ER. Does it cut out when it is turned up loud and you are digging in? If so you may be at the limit of your F1. I think that like quite a few of the early class d bass amps that their continuous output ratings were a little optimistic. Quote Link to comment Share on other sites More sharing options...
yorks5stringer Posted April 23, 2016 Share Posted April 23, 2016 Do a search, there have been a lot of threads about this, mostly on talkbass but some on here too Quote Link to comment Share on other sites More sharing options...
electriccheese Posted April 23, 2016 Share Posted April 23, 2016 I have a F500 and used some years the F1. I don't if it's the same, but I had the same trouble in a place I used to gig with a poor voltage stability. I solved it connecting the amp to a voltage stabilizer (I don't know if it's the exact name in english). Quote Link to comment Share on other sites More sharing options...
