Is there such a thing as a modestly priced, ~8 channel, possibly built-in FX, slim, light, clean-sounding, low power using Mixer?
This looks pretty great. Did you use one? Did it have a successor? Danke Skab.
I used its precursor, the one without the digital FX. In fact I still have it. Fuse got fried from a dodgy generator at a party up in the mountains, but apart from that it still works. Looking at their homepage, it looks like the successor is a 12 channel monster with 4 busses. And it costs $800. Boo. Failing that, check out the Mackie 1202 series, can be had for dirt cheap used, although not quite as compact as the Yamaha, they are much more rugged. Be prepared to do some cleaning if you buy a used mixer. I just got a used Mackie 1202 today and I found this tutorial:
it's 12 channel, but i used a soundcraft EFX-12 for years. it seems to be exactly what you want aside from the size. really great mixer.
