Design flaw with certain impedance mics

By Van

from Ann Arbor, MI

Comments about M-Audio Octane 8-Channel Mic Preamp with ADAT Lightpipe:

I discovered almost immediately that when plugging my overhead condenser mics into channels 7 and 8 with phantom power engaged, that a fairly loud buzzing and humming noise came up. The noise slowly faded away after about 10-15 min. I switched chords, outlets, ground scenarios etc. and it still happened after a cold start. The weird thing was that if I engaged the -20 db pad on channels 7&8 the buzz went away, even with the gain all the way up. M-audio sent me a 2nd unit to try to see if the unit was defective. Same results with the 2nd unit.I took the Octane to a local high end recording studio to check it with other mics, cables and power supply. Same results with my mics (Marshall's & Rode) but when some Neumann U87's were used, no buzz. We started trying some other mics with different ohm ratings (ADK-A51's, Oktava mk012's, Shure KSM-141's). Bottom line, any mic less than 200 ohms caused channels 7&8 to buzz. I informed M-audio's tech support of this and they did their own testing of the Octane units at their factory with various mics. Sure enough, they have admitted to me that it is a design flaw. So, if you have an M-audio octane or are looking to buy an Octane be careful about the condensers you use. Anything less than 200 ohms will more than likely cause you a very annoying buzz or a 15 min. warm up time for the noise to go away.
