I have a DSL40C which I think is faulty but don't know what the problem is? I'm fairly inexperienced and don't know much but the sound that is coming out of it is very abnormal. The amp is only 6 months old and just suddenly started to make a loud noise that would continue even after I turned it off! The third time it happened it sounded like a siren. This would occur about a minute into playing. On full power it was on standby and making a light crackling noise and I wasn't game to turn it on again. I've tried different leads and powerpoints and it has not been resolved. Could it have something to do with the preamp?
Helllo Shannon,
As your amplifier is still under warranty we would recommend that you take the unit back to the dealer it was purchased it through so an engineer can check the unit over for you.
