maybe they just expect you to stick it in a portable rack and you won't hear it as much(?). i'm pretty sure the electrical connection is alright. of course i'd prefer that it didn't make any noise, but i'm still not sure how concerned i am about the buzz, as long as it doesn't show up in recordings. kind of like a flourescent office light.). i can hear it anywhere in the room if i listen for it, but its not much louder than the lowest-running fan sound on my powerbook (though it's certainly a more biting, "buzzer" sound than the peaceful "whoosh" of the powerbook fan. I just got my 828 mkII a couple days ago and i'm still configuring my little studio room for it but i definitely notice the buzz coming from where the power cable is plugged in on the back/right side of the unit. Sorry for the rant everyone, but really i just want to get back to making music. Does anyoe know of any other gear in this price range with such a short warranty period? but seems fitting once you find out that the 828 only has a 90 day warranty(!?). MOTU have a flat rate $50 repair policy which is strange. Regardless, i don't think that MOTU users should just have to live with with the buzz. The question is is it affecting the majority of units? Only two responded earlier about the buzz but i would be very interested in hearing whether people think i will be able to find a new unit that doesn't buzz. There are a ton of people on this forum with 828mkII's. not to have to start researching other units again. But there are a lot of good things about the mkII and the new Cue Mix DSP and what i want is a working 828mkII. These problems are frustrating but simple to fix - simply return the unit to store for a refund. The hiss persists regardless of whether i have any gear connected to the 828 or if i turn the master volume down to nothing. Plug them back into the 828 mkII and there's the hissssss again. I've tried plugging my reference monitors (Tannoy Active Reveals) into other pieces of gear in the same rack and the noise disappears. The problem is actually worse than with my original mkI.ī) The analog outs all produce a terrible amount of hiss. It's not super loud but loud enough that if i don't have music playing it makes sitting in my studio annoying. The Duet is another option from Apogee.A) The power supply is buzzing. When I got rid of the 828mkII, I stopped having issues and my setup is much more stable. I will say that an Ensemble sounds miles ahead of the 828mkII.don't know about the 828Mk3īut the product looks interesting because of its onboard DSP ( a trend in audio interfaces ) and I am sure they have updated the converters. I have owned a Midi Time Piece AV and it would never remember its settings even after I replaced the internal battery twice.I don't see buying another product from them due to my own experiences with two of their products. MOTU is a cool company and has provided some bang for the buck over the years but somehow each of the products I have had failed in some way after a while ,or were just not stable for me. I found a couple of ways to get it going by toggling the sample rate setting in the Audio/Midi setup panel bu,t after a while the 828mkII would not even go through its little "boot Up" and I got frustrated and left the unit for an Ensemble. It was a frustrating device from time to time because there seemed to be no reason for when it was not working right. My 828mkII made the high pitched tone at times too. I had a MOTU 828mkII for a couple years before upgrading to and Ensemble from Apogee.
