Hi
Clicks are usually a bit of DC on either the 'source' circuit or the 'destination'. Thumps are generally having MORE DC or if you have 'FET' switches that have DC in the audio path. If it is 'desk wide' then it may be you have DC from a 'mix amp' as it is unlikely ALL channels will be faulty, or ONE channel is seriously bad and when it is already ON then it is charging up the bus. Alternatively you have a 'ground' problem and the ground of the switches is not the same as somewhere else that should be. You need a half decent multimeter and logical thinking to find out where the problem lies.

Hi Nik,
No, it should be quiet. What kind of noise are you getting with the mute/un-mute cycle?
best,
Ike

Hi everyone!
like a recent discussion here i have really bad noise problems on the bus! I recently changed the powersupply of my elite and got a new one from neotek which solved a few problems i had for ages. Now i get really bad hum when i switch to bus on the channels. Also all channels make noise when muted and unmuted. Does that sound like something common?
Thanx
