Hi everyone, long time lurker first time poster here. I've been operating a small project studio for 4 or 5 years in the fens of the UK. I've recently lucked into my first class-A gear; an old Audix B100 broadcast console with a handful of spare modules. It seems to be pretty much complete, with the original 24v power supply.
I've written to Audix to request schematics and as much information as possible, but in the meantime decided now would be a good time to start posting here, organise my thoughts, hopefully meet some knowledgable people and generally vent my (perhaps premature) excitement!
Depending on feasibility, I would like to use the preamps, compressors, and perhaps the routing & summing matrices in a multitrack setup. This probably depends mostly on how the summing is arranged now; if the modules (along with routing and output modules) provide a mic/line level signal or if the summing section steps everything up together later in the signal chain.
Right now I want to get my head around how the summing and routing works so I can make a decision and get started. I'm resisting the temptation to try and power the desk up so I can carefully clean / check it over without worrying too much about killing myself.
The transformers seem to be quite exciting; I think they are Marinairs after reading some posts that came up in searches on here: T1442, T1447 and some others. Hopefully I can make a plan that results in surplus transformers for some exotic 24v DIY projects to slot into the desk, depending on the capacity of the power supply 8)
If anyone happens to be familiar with these modules / desks, please do chime in! My progress is likely to be slow, but I will keep this thread updated as I go. In the meantime, here are some pictures of the component side of some of the boards:
Preamp input module:
Routing Module:
Output Module:
Compressor Module:
