Hi, I just received my first Einstein flash. Everything works fine but there is kind of a "buzzing" sound coming from the modeling lamp as long as it is turned on. As soon as I turn off the modeling lamp the fan is all there is to hear. Is that okay? I'm from Germany using 220V. Thanks in advance! Regards, Michael |

That is not uncommon, particularly if the lamp is dialed down. Regular incadescent lights will do this in the home too if on a dimmer switch. |

I'm currently using Aurora Fusion Flashes and their modeling lamps do not produce any noise. So I was just wondering if everything is okay with the Einstein. Regards, Michael |

Michael and PCB Tech -- I just noticed the same buzzing noise from the modeling lamp on my Einstein640 as well. I just brought it over from the U.S. (120v/60hz to Germany 220v/50hz) but don't remember it making any noise like this before in the states. The buzzing is consistent from minimal to full power. I was wondering if the bulb needs to be changed because of the power difference? (I've learned by popping a couple 110v house bulbs accidentally into my 220v sockets!) The buzzing just doesn't sound good and is a bit annoying without some music on in the studio. PS: I'm SO happy the Einstein640 is designed to be internationally friendly, with 95 to 265 VAC power and the 2.4ghz wireless CyberSync/CyberCommander system! =) |

There is no need to change bulbs due to mains voltage. This is automatically regulated in the light. |
