James, What you are saying is you must unplug it to turn it off. That means the entire time it is plugged into an outlet it is on. Nothing mysterious about that, and that's pretty much the same as any electrical device works, particularly those with low voltage circuitry. However, unless it is operated with a remote ON/OFF device, something that sends a signal to a system that fires the on/off relay, it is always on when it is plugged in, thereby making it susceptible to electrical failure when you least expect. This isn't rocket science--it's basic electronics 101. Don't take my word for it. Google search information about homes that burned to the ground because of an electronic device that was left turned on. Cheers, Gary

And, anything electrical can develop a short circuit--anything. That's what the internal fusing in the power supply is for. Behringer doesn't make those power supplies, they are OEM, supplied by power supply mfrs who get the UL/CSA etc. certification for them. They wouldn't be certified as compliant if they could cause a fire due to an internal short. The certification comes from testing. If it's plugged into an electrical outlet, and does not have an on/off switch, not only is it vulnerable to a power surge, but as Diki stated you cannot select the sequence the equipment is turned on or off, which in some instances, could cause serious damage to other equipment. Like I said, I have a small Berry miser here that is used for keyboard mixing that has run 24/7 for at least five years. If I have to make a connect or do something else that would create the speaker damaging POP -- I simply roll the Master Fader on the mixer all the way off and then make the connect. What I find really interesting is that when your TV is turned off by remote control it's not really off. Instead, it's in a standby mode. It still draws power and over a year's time that can amount to a significant increase in your electric bill. Inside sets like that there is a *separate* very small transformer/power supply circuit for that purpose. While it does draw power, it is minimal, plus it is not like the actual larger transformer and supply is operative all the time, it isn't. That larger supply is physically disconnected from the AC mains via electromagnetic relay contacts, which does the exact same thing as a manual power switch. Even if Behringer did install a power switch on the mixer itself, it could only disconnect the low voltage DC supplied by the separate power supply. It would not be able to turn the power supply off nor disconnect it from 5he AC mains. It is, however, very likely that the cost factor does come into play here. After all, it is the consumer who drives prices ever downward via buying habits. At any rate, I wouldn't be overly concerned about the lack of a power switch on such an economical little mixer. And I'm not. --Mac

It's not a big deal, at least for me. I keep all my equipment on a surge protector, and at the end of the job, and at home before I got to bed, the surge protector is turned off. And, during electrical storms, which we have lots of during the year, the surge protectors are unplugged. Maybe I'm a bit overcautious, but having been nailed on two occasions by power surges, one that originated from a lightning strike on an underground TV cable, and blowing everything that was still plugged in, you get a bit gun-shy. And, the folks that live just two hundred yards from me had their TV short out in the middle of the night, which set their home on fire. They were not injured because the smoke detectors alerted them in time and they managed to get out of the house before the fire spread, but the overall damage took several months to repair.
