#82 RME ADI-8 DS teardown and repair

 A seller on eBay had had a couple of these units listed as faulty for a few weeks, and once i had a bit of spare cash, i decided to take the dive and snap these up. The impetus was two-fold - on one hand, as it turns out, there seems to be a bit of a "disease" going around with power supplies in RME rack units; and on the other hand not long ago, i had noticed an ad from a person in this area actually looking to buy exactly one of these units.

Some extra motivation was prompted by looking up some prices for this thing. Borderline-eyewatering, i'd say. It seems to have retailed somewhere in the 1500e area at launch (1280GBP in 2003), and still selling for anything between 500-800e used (on Reverb.com or Milk Audio Store). Gulp.....

The shipping time was spent more or less being anxious whether i had bought a couple of lemons (for all i knew, the power supplies were missing altogether), or whether i would manage to catch a break and manage to fix these up easily and make some extra cash for the holidays.

#81 MOTU Traveler teardown & upgrade

As a follow-up to the recently posted MOTU Ultralite teardown, i had to grab this as soon as it popped up in my search results, because it had a price i couldn't ignore or refuse, and it had the ideal feature set for recording my band's jams and rehearsals. While the former had most of the features i needed in the 828mk2 i had been using, but in a smaller form factor, this Traveler packs more of the features i need (two extra mic preamps, while retaining the -10dBV/+4dBu line inputs with optional 6dB boost), in an intermediate form factor, as well as having a full 53dB of gain available on the mic preamps, but without weirdo custom potentiometers to wear out. Just about best of all worlds, really, especially for the paltry 85e this cost me. And as the cherry on top, it even has a separate battery input - hello, fully mobile recording sessions...

 

 

#80 MOTU Ultralite teardown

In an interesting turn of events, i actually did NOT get this one as faulty. It was more to relieve one of my 828mk2's from rehearsal-place-recording duty, and on the other hand, i managed to get it for quite cheap. In the context of, faulty ones had similar asking prices, so there's that.

#77 MOTU Ultralite mk3 Hybrid part one: teardown

Yet another score from the "morgue" - this time around, a feature-packed little bundle of audio joy, namely a MOTU Ultralite mk3 Hybrid. This was up for sale as "no longer powering up", and for a two-figure price, i couldn't pass it up.

#75 Focusrite Scarlett 2i4 (1st gen) teardown & repair

Perhaps a bit anachronistically, only *after* getting my hands on the previously-torn-down 2i4 gen2, i also came into the possession of a 2i4 gen1, that was no longer being detected completely / correctly by the computer. But hey, better late than never, right? I also grabbed a working one (because the price was near-irresistible), to have a known-good source for the firmware, in case that was the issue.

#73 Focusrite Saffire 6 USB 2.0 teardown

Initially, i was thinking of getting and modding a Scarlett 2i4 to use as an updated and more flexible in-ear headphone amp, to replace my aging modded M-Audio Fast Track (incidentally, the subject of the very first article on this blog). I even ended up with two 1st gen ones as well as two 2nd gen ones. But recently, i came across yet another deal i couldn't pass up - a Saffire 6 USB for a nearly ridiculous 36e, shipped(!). Virtually the same structure as the 2i4's, but i can definitely get more money (back) from reselling those, and keeping the Saffire. That, and i had come across instructions for a mod to the Saffire 6, to enable stand-alone operation.

#72 MOTU 828 mk3 teardown

Yet another eBay score - caught this one with a blown power supply. Blown, as in, skidmark inside the casing, circuit board scorched, tracks vaporized. But maybe i'll make that into another article on its own, someday. In the mean time, let's take a peek under the hood of one of these arguable "classics".

#70 MOTU Audio Express teardown

This summer's "already" been quite fruitful, gear-scoring-wise anyway. This find cost me a colossal 86eu, with allegedly none of the outputs working. This, in the context of it retailing for a somewhat eye-watering 500eu(!!!) or thereabouts, brand new. On the bright(?) side, it came with the original packaging, manuals still in their plastic bags, as well as a USB and a Firewire cable to boot, both also still factory-packed. So why not?

#69 Focusrite Scarlett 2i4 (2nd gen) teardown & repair

For a little while now, i've been thinking of "upgrading" from my old-but-modded M-Audio Fast Track to use as an in-ear monitor amplifier, and the Scarlett 2i4 caught my eye. The mono/stereo direct-monitor selection, as well as the hardware-switchable pads on the inputs made up just the right feature set, in addition to it being usable as a mobile recording interface. As it happens, just the other week, mere days after having saved an eBay search for 2i4's, an email notification revealed a 2nd gen allegedly-faulty unit being up for sale from Italy. I quickly asked the seller about shipping costs, and ended up sealing the deal for an even 50e. 

#61 MOTU 896 mk3 Hybrid teardown (post-recap)

Since relatively recently acquiring the MOTU 8M, once i got around to swapping it out for the 896 mk3 in my recording rack, i figured it might be worth doing a quick teardown of the latter, before i sell it off. I've done a really brief one over on the BadCaps.net forums when i first bought it, but it deserves some higher-res photos and a more detailed documentation of its guts. Do keep in mind that it got re-capped as soon as i got my hands on (or into?) it, so the electrolytics are not stock. But
without further ado...

#59 MOTU 828 mk2 teardown

Even though this is the 4th or 5th of these units that has gone through my hands, looks like i never documented a teardown of one - shame on me! Time to rectify that issue then, wouldn't you say? I grabbed this one off eBay for about 60 bucks or so, delivered. On one hand, because it was pretty dirt cheap at this money, and on the other hand, because it will be involved in a project idea i had a good few years ago. And yes, "as usual" (by now), this one had a busted Firewire connection, but for my own (nefarious?) purposes, i don't need that anyway.

#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?

#36 TC Electronic Digital Konnekt x32 teardown and repair

We're having a "productive" period, as it turns out. This time around a TC Electronic Digital Konnekt x32 audio interface / digital patchbay is on the chopping block. Or on the operating table, rather - i do indeed hope to repair, rather than dismember and mutilate this thing.

I managed to catch this, along with a twin of its, for under $200 / 200e delivered, as a "job lot", both sold as untested / faulty. The first one was shown powered up and possibly working fine (several LEDs on the front panel being lit), so potentially fine, pending tests. This second one though, not quite so much - only the blue LED halo surrounding the power button lit.

#34 MOTU Traveler mk3 teardown and repair

Hunting for faulty stuff on eBay has been fruitful yet again: this time, a MOTU Traveler mk3 Firewire audio interface. The reported issue was by now, the "classic", dead Firewire.

A pretty comprehensive little package, with loads of features shoehorned into quite a compact package - 1RU thickness / height, but only about 80% of the width.

#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?

#3 MOTU 8Pre teardown & gain adjustment pot replacement

On the latest drum tracking session i surprisingly discovered that channel 8 on the MOTU 8pre in my recording rig was noisy and useful-signal-less. This same unit had a similar issue with channel 6 when i bought it (as faulty, with a shot Firewire chip).

Fortunately, when i was about to take care of ch6, i got two replacement pots. When investigating the issue, i had read it's a relatively common occurrence, so i figured that as long as i'm contacting the local MOTU distributor, might as well get an extra / spare one, just in case (especially since i had two 8Pres at the time).
