How to use opencv extra modules?

Amp modules look great, but how would I use them?

• I have just come across a http://salvationmods.com/, (based on http://www.randallamplifiers.com/Amplifiers/MTS-Modules/) which is interesting and neat (http://www.youtube.com/watch?v=_eVH5vUR8u8&feature=g-all-u). However, what I don't understand is how I would use one of these in my own rig. They are, but how would I hook them up? Could I use one to drive a speaker cabinet? Do they need to be in an enclosure?Basically, how would I use one of these modules?

• Answer:

  The MTS modules are preamp modules but they are not designed for standalone preamp use. They are missing two critical features of standalone preamps: some kind of standard input/output (1/4", XLR, etc) and a power supply. They have an electrical connector on the rear of the module that handles I/O and power: gold tabs sticking out of module at top of http://www.bazaar-world.com/guitar-amp-4106-RANDALL-MTS-MODULE-PLEXI. They are designed to slot into the Randall MTS line of amplifiers/preamps, or certain Egnater amplifiers (not sure which of those). The Randall/Egnater amp supplies the MTS module with power (correct voltage and current) and contains the inputs (and output in case of RM4 preamp), both through the electrical connector on the rear of module. You can see amplifier side of the connector (blue) in http://www.musiciansfriend.com/amplifiers-effects/randall-mts-series-rm22hb-18w-tube-guitar-amp-head/423973000001000. All that said, the easiest way to use the modules is to buy a Randall or Egnater amp that uses them. If you don't want to buy an amp and still want to use them you need to hack together some kind of DIY solution. This would involve finding schematics for modules (some appear to be available), trying to rig up some kind of connector that will work for the I/O and power, or hard wiring those functions to the module (the latter would defeat the swapable nature of the system but would be easiest if you had only one specific module you wanted to use). A brief search shows some people modding their own MTS modules in the same way that Salvation Mods is doing, but no one appears to have duplicated the functionality of the MTS amplifier itself. So you would likely be treading new ground. This is a doable DIY project but fairly advanced; not a beginner DIY audio project. The hardest part might be sourcing that blue connector, if Randall/Egnater went with a custom part for that.
