Pops and Clicks?

    I am the new owner of a Focusrite 18i6 and i must say it sounds great! the built in pres are clean, and the 6 external pres i got running into it are as clean as a whistle. BUT. I get intermitant pops and clicks that i just cant seem to find a reason for. Sometimes its just static at the end, but when i was recording my cover of Enter Sandman for my cousin, the floor tom track in the beginning was like popping popcorn instead of a beautiful tuned Pearl VSX floor shell. It was quite unnerving and disapointing i must say.

    IF there could be any assistance to my problems then That would help greatly.

    Thank you

    The 18i6 is a nice unit, and I was certainly impressed with the sound of one I heard recently. It's a pity that they designed for a maximum level at the rear panel line inputs of only +10dBuFS, which means that when connecting external pre-amps, you have to throttle back on their gains or use attenuators. I did, however, raise more of an eyebrow when I saw that the 18i6 had a USB interface rather than FireWire, but I suppose that Focusrite has seen that the number of new computers with native FireWire using the TI chipset is close to zero, and they made a marketing decision.

    You don't say what type of PC and operating system you are using with your 18i6. My guess is that your pops and clicks are not directly a problem with the Focusrite product, but that you have a USB latency problem in your PC or Mac. Focusrite has a rather trite Answerbase for the 18i6 on its website, which in turn points to pages giving methods for reducing latency on a PC, but there's not much help for Mac users.

    If you have done all the usual things to reduce USB latency, try taking the interface to a different computer to see if the problems are the same as on yours.

    Alright I have put the gain down on the external pres, I think that may have been one of the starting factors.

    I have tried most, if not all the optimization things for Win7, my machine is Asus, Phenom X6 1060, 8GB Ram, 1TB, and im using Reaper.

    well the external pres are fine. i noticed the only channels that are distorting with static and pops are the builtin pres, and they are set at 4 oclock
