BugBrand Ambassador Battery Powered Modular

Here's some first pics of my new (just-about) portable system. It runs entirely without the need for mains electricity. Powered by two chunky 12v SLA batteries and with a pretty meaty internal power amp, this allows modular squelch almost anywhere (..first performances were outside by the Bristol harbour during the wonderful Venn Festival weekend). Soon this will be solar powered - going to pick up a couple of powerful panels from the Post Office later today...

This has been called the Ambassador System. Its a pretty chunky frame - at the moment holding three frac-racks of modules (with space for a fourth down below).

Here's a detail of the front. I made a frame for 5u tall frac-width panels so as to fit in a system mixer. This mixer has big stats! ::: four input preamp channels, four aux sends (you can never have enough! There're two sending up to the frac modules and two sending to 1/4" output jacks), plus main channel with C.Anderton Opt-compressor.

Then there's a couple of rough'n'ready panels to hold:
Power Regulators --- I've regulating the 12v bipolar supply down to +/- 10v using 317/337 circuits. Not totally sure if I need to do this though...
Power Connections --- to hook up solar panels etc
Power Stat LEDs - LM3914 based 12v battery testers to see how well the SLAs are charged
Power Amp - actually pretty meaty 20watt amp - its certainly loud when inside the studio! And, with the chunky batteries, this can chug out loud sounds for many hours!

& here's some more details of the mixer build..... repetition!

And here's a wobbly YouTube Demo video::::::
