About This Listing

For sale here is an 80s Audio Developments AD031 'Micro' mixer. It has all the modifications you'd ever want for multitracking, and they were all implemented very well – it sounds about as good as one of these will ever sound – but there are also a few significant problems. Please read this listing carefully, and ask questions if you have any.

First, the major modifications:

Transformer balanced direct outs added, using Lundahl LL1517s, accessible via a female DB25 jack on the left side of the mixer


Direct outs can be driven directly from the line / mic input or from the fader, allowing for pre-fader direct outs and a post-fader mix simultaneously


Pre-fader mute switches added


Rebuilt PSU; this is about as quiet as a single-rail AD mixer can sound


Recapped throughout


Aux send disabled to accommodate direct out and switching modifications

And the significant problems:

The mic / line select switches on channels 5 and 8 should be replaced; they usually behave after tapping or working the switch a bit, but pass signal intermittently on occasion and sometimes make some noise


Channel A compression does not work; the channel passes no signal when the compressor is engaged, and the meter is not flush with the aluminum plate


There are a few cracked knobs; see photos


The mixer is basically in correct working condition aside from the faults described above – it's about what you'd expect from a mixer of this vintage; i.e., the pots and switches are sometimes a bit scratchy in motion, but quiet in place. The faders all seem to be quiet in motion. The phantom power is solid and reliable, switchable per channel.  I do not recommend using the 'Mic Att' position, it doesn't sound great on any of the AD mixers from this era; an inline pad is a better choice.  

The mods are pretty fantastic, and give this mixer exactly the flexibility you'd want to have. It sounds as it should; the AD mixers of this type don't have endless headroom because of the power supply design (they were meant to be field mixers, after all) but they have a ton of character and I've found this to be a really useful mixer. The preamps are fantastic for guitars and a really cool choice for some drum attitude. The EQs are just awesome; it's very fun as a summing mixer for a bank of 8 channels.

Overall this mixer is in good cosmetic condition consistent with its age – it's seen some action, but seems like it was basically cared for. It's not spotless; I've tried to represent it fairly in the photos.

I have the original case for the mixer and I am happy to include it in the auction, but please be aware that shipping costs will rise significantly if I ship in the case – it's big and heavy!
 
I'm selling this mixer in working used condition, with known faults as described, guaranteed not DOA, and in good faith, but otherwise as is – the buyer understands that this is a vintage piece and that it will require further tech work and maintenance to get it to 100%.  Again, please ask questions if you have any, and thanks for looking.
