Here I was, stuck with my ancient Yamaha 12/4 mixing desk. It did the job fine, but I was looking for an excuse to replace it. Then, one day, the heavens smiled on me as I accidentally shoved the power supply off a table and cracked the entire thing. With the inner workings exposed, it would no longer be safe to use it to power the desk.
Surely, there would be no way this old power supply could be replaced? Finally, I could buy myself some fancy digital mixing desk I had no real use for! I mean, the Yamaha desk worked pretty well and was easy to use, but I was aching to get me some shiny new gadgets!
But no, Thomann just had to ruin my gleeful anticipations, by having a replacement unit on offer which was not only quite affordable, it also was smaller than the original unit so it would be easier to carry the entire thing around. There went my dreams of a shiny new desk. No reason to replace the old with the new, just the same old trusty desk I had been using for years. Powered by an affordable replacement power supply that was delivered to my doorstep in a matter of days.
Well, fine, Thomann, if you're gonna act that way, I'll just order a shiny new guitar amplifier!
TL;DR: It powers the desk, is affordable, and is smaller and easier to carry around than the original unit. If you need a new power supply, this will suit you.
