So you think you can Route/Amp/Fx switch...check this behemoth from MI Effects/Amps.

MI posted this up on another forum...their switching system/mother ship controller for their upcomming NAMM apperance...


The main controller is a 40 button footswitch, from which we can:
- turn on or off 16 pedals using a MIDI true bypass switcher.
- send the audio from the pedals to one of ten amps.
- The top row of buttons becomes the footswitch for any of our amps, so we can change channels etc.
- Any FX we have in the loop are switched to the active amplifier.
- The output of any amplifier can be sent to one of 8 different cabs.




1) Pedal bypass looper: 16 relay bypass loops. The cool feature with this is we used latching relays which means that idle current consumption is very low (about 10mA), so it can actually run off a 9V battery!


2) Amp Input switcher: Takes the output of the pedal looper and connects it to the input of up to 10 amps. We could have built this into the same box as the pedal switcher, but decided to modularise it. It has jack sensing on it, so it won't switch to an amp if it's not plugged in. Once again, can be battery powered


3) Amp channel switcher: This was obviously customised for the amps we're taking. Each amp has an isolated ground, so no ground loops, but also means that it can switch functions which aren't necessarily referenced t ground.


4) FX Loop switcher: We're going to run some effects in the amp loops, so this allows us to make these effects 'follow' whichever amp is currently being used. This means you don't need 10 sets of effects if you're running 10 amps.


5) Amp output and Speaker switcher: The big bubba. This box can take the 8 and 16 Ohm outputs of our 10 amps, and switch them to the speaker outputs. Amps which are not connected to a speaker have a dummy load connected, just in case something happens. In total, there's 2000W worth of dummy loads in this box. Finally, the active amp can be routed to one of 8 different speaker outputs. The unit contains sensing to make sure a speaker is plugged in before switching to it. It also has a safety mechanism if a speaker is accidentally disconnected.


Here are the dummy loads! Each resistor is 50W power handling





Can't wait to see this thing all hooked up!!!
