Hi folks... I did a test and recorded all 8 analog ins from my RME, and I would get random clicks on random tracks for each recording...but not clicks when recording through ADAT ins... Any tips? rich |

some good solutions to try out there. I've never had this problem in other buildings, so it's a little frustrating. The grouding rod seems like a good solution too... I guess I'll end up trying them all... |

he did specify in his first post that both his racks and the computer are going thru line conditioners, and the computer is on UPS. i'm assuming that means there isnt also an 8 foot console plugged direct into the mains ! i would definitely recommend a ground rod - you can detach your earth from everything/everyone else in the building, and its one more thing you can eliminate if the problem continues - and any problem solving like this is just a case of systematic elimination. its also wont cost the earth (sorry!). |

Forget the ground rod for now. Do you have any power conditioning/filtering? DC |

Good suggestion. I have no use whatsoever for power "regulators" that use a switched relay tap autotransformer, like one Tripplite model. They have been known to put clicks into sensitive Preamplifiers whenever they cycle between high and low voltages. BK |

Hi Bob. Which Tripp-lite model? They seem to be the cheapest (starting at only $500) and pretty much what I can afford now. Is there any other model you can recommend? thanks! rich |

As a quick test, you might try powering the Multiface off the same UPS as the computer. If the UPS is the type that always runs power through the battery, about the only noise that can get through would be on the ground line, not on the power lines. Joe |

Argghh... Well, I did go ahead and get the Tripplite before I read your post Bob....(but the clicks were there before I installed it anyway). But, it's the online double-conversion (which runs off battery 24hr a day) so I'm hoping it's better than their regular ups and conditioners. |

Anyhoo, the only clicks I get now are from the fridge (turning on and off). HUGE clicks, but that's once every few minutes. And when I'm tracking, I pull the fridge plug... |

I once did a session in someone's house and whenever the fucking refridgerator would cycle on we'd have to retake. |

Rich, Sorry I haven't gotten back sooner. If you haven't already found a fix, here are a couple of more things to try. Is there a way to move either your system or the frig onto a different branch circuit (i.e. different circuit breaker) of the power panel, possibly using a long extension cord as a temporary test? This might help to issolate the problem a little more. Also, how old is the building? Are all the branch circuits three-wire (hot, neutral & ground), or are they trying to use the neutral or conduit for the ground? You could also be getting a ground loop between the Tascam and the computer, try lifting the ground on the Tascam as a test. Joe |
