#63 M-Audio M-Track 2x2M C-series teardown & repair

Boy, that's a lot of M's up there... But yeah, here's another eBay score, bought as faulty. Basically, because it was too cheap to pass up, even if it's unrepairable - a paltry 30eu. The ad said it will no longer power up, save for the phantom-power indicator LED, and won't be detected by a computer. But before troubleshooting, it warrants a thorough inspection, inside and out, wouldn't you say?

#39 M-Audio Profire 2626 teardown and repair

Ebay strikes again - this time, a pretty damn cheap (to acquire) M-Audio Profire 2626 Firewire audio interface. I maintain it's still the cheapest way, to this day, to get 24 inputs and outputs to and from a computer. Most other 1U (rackmount) interfaces will give you 8 mic preamps but only one bank of ADAT. The ones with two sets of ADAT I/O will cost you a pretty penny, though.

Either way, this was sold as "not detected by the computer", so my bet's on the Firewire chip being toast, "as usual". Can you see a pattern emerging here?

#32 M-Audio (Avid) Fast Track C600 teardown & repair

This little bugger, an M-Audio / Avid Fast Track C600, was listed as faulty on eBay - description said it would no longer power up, regardless of it being bus-powered or having its own external power supply connected. Got it shipped for 30eu / $30, so why not?

#1 M-Audio Fast Track (mk1) gain and 18650 Li-Ion mod / upgrade

So i had this old, pre-"facelift" M-Audio Fast Track since 5-6 years ago, which had been lent to a bandmate for the last couple of years. A few weeks ago, i traded him up to a Scarlett 2i2, and i got my Fast Track back.

And then i got thinking - it has the convenient mono/stereo switch on the front (to have both inputs in mono, or input 1 on the left and 2 on the right), a headphone output, doesn't need a specific power supply (it being bus-powered)... 😏
