ReeV0 Posted September 24, 2008 Share Posted September 24, 2008 hi guys well, I just received my Warwick ProFet 3.2 amp today, but I am sad to say i am pretty sure it is faulty. It makes a terrible buzzing noise when connected to the cab, or to headphones, with or without the bass plugged in. There is nothing I can do to prevent it buzzing, it buzzes like crazy regardless of the volume or gain or EQ levels. I do not wish to open the amp up, as im pretty sure this will void the warranty, so I need your help as to what to do with it. many thanks guys Quote Link to comment Share on other sites More sharing options...
ahpook Posted September 24, 2008 Share Posted September 24, 2008 if it's new, talk to the people you got it from...if it's making buzzing noises whatever you do to it then it's broken. sorry...hope you get it sorted. Quote Link to comment Share on other sites More sharing options...
stingrayfan Posted September 24, 2008 Share Posted September 24, 2008 Got any dimmer switches nearby? They're terrible for causing buzz - even if they're in the next room or on the other side of the house. Failing that - I've got a more powerful Profet 5.1 for sale that doesn't buzz.

Machines Posted September 25, 2008 Share Posted September 25, 2008 Definitely send it back - shouldn't do that. Quote Link to comment Share on other sites More sharing options...
ReeV0 Posted September 25, 2008 Author Share Posted September 25, 2008 i think it has something to do with the power supply. should the plug have a 13A fuse in it? Quote Link to comment Share on other sites More sharing options...
alexclaber Posted September 25, 2008 Share Posted September 25, 2008 Try it in every room in your house with all the lights switched off. If it does it everywhere then the power supply is faulty and you should return it. Alex Quote Link to comment Share on other sites More sharing options...
ReeV0 Posted September 25, 2008 Author Share Posted September 25, 2008 yup, unfortunately it does it everywhere Quote Link to comment Share on other sites More sharing options...

[b]Never[/b] use 13 amp fuses. I don't know Warwick but I would guess that you shouldn't put anything larger than a 5 amp fuse in the mains plug.

chris_b Posted September 25, 2008 Share Posted September 25, 2008 If you have a problem with the amp and the value of the fuse is too high you run the risk of doing some damage to the amp before the fuse blows. You really want to blow the fuse in the plug, as it's easier to change, and not the fuse in the amp. A 5 amp fuse should be high enough to cover most 500 watt amplifier's power needs.

ReeV0 Posted September 25, 2008 Author Share Posted September 25, 2008 well its just that the amp came with a 13A fuse, which i thought was a bit high. i've tried the amp with a plug with a 5A fuse, but still the insane buzzing is there Quote Link to comment Share on other sites More sharing options...
alexclaber Posted September 25, 2008 Share Posted September 25, 2008 [quote name='jjl5590' post='291776' date='Sep 25 2008, 02:05 PM']im confused[/quote] Take it back, take it back, take it back! Regarding amp fuses, use whichever specific type of fuse is specified in the manual. Most amps will not draw anywhere near 13A in normal use but there can be quite significant inrush current on switch-on which could require either a slow blow fuse or a higher rated fuse than you would expect.
