For the last ten years I've been hosting karaoke shows (usually three or four per week). For much of that time I have used and been delighted with my Mackie 808s. Last week I played at a new club where there was some electrical problem with an outlet that I was using. The Mackie didn't make any sound ...just wouldn't turn on. Naturally I went out to the car and brought in my back-up (Yamaha thousand watt powered mixer similar to the Mackie). Proving to myself once again that I am, indeed, an idiot, I plugged it right in to the same surge protector as the Mackie. I switched it on and it made a semi-loud popping noise and then went silent. So I took it across the room plugged into a different location and bingo... it's been working fine ever since. No such luck with the old faithful Mackie. Anybody out there with some magical, low-cost cure?
