I had an amp out for repairs (long story - it went to the UK service centre, sat there for a while, went to Italy to the manufacturer, got fixed eventually) after a firmware update bricked it. Anyway, it's back in the rack now:
In the rack, we've got (top to bottom)
- 4-channel amp for bi-amping the main speakers - 4x 1500w
- 2 channel amp for the subwoofers - 2x 3000w
- 4-channel amp for stage monitors - 4x 750w
How they get those power levels in a box that big is voodoo to me, but it seems to work. The whole rack weighs less than the 2x2500w Crown amp that came to Owston.
Sitting on top is a mixing desk which also works rather nicely for on-location recording - you can record up to 32 channels (30 inputs plus a stereo mix) straight to a USB solid-state drive (disk drives just aren't fast enough) and mix down later. I've got a few bits of recording work coming up with various bands at Sheffield University, so watch this space.
The most recent recording work (which I'm hoping to be able to share at some point) was with a choir of 14. I set up a few mics around the cathedral (St Marie's in Sheffield) but ended up using the mid/side array for the finished product. The idea there is you've got 2x mics. One points forward and forms the central image, and then there's a figure-of-8 mic which you aim side-to-side, placing the choir in the null. By splitting that signal, panning it hard left/right and inverting the right (negative, since the mic is dipole) side, you can then choose the stereo width just by adding more or less of the "side" signal.
If anyone would like to look them up, the mics were a Beyer MC930 for the mid, and a SE VR1 ribbon for the side.
