I have a designer coming in who wants to use 10 Series 2 Lustrs, given that we are in a concert hall there is some concern about noise levels of the fans. I have been unable to find any information in the documentation for the units and also have no personal experience with them to use as a guide. I have informed the presenting company that they may or may not find the noise level unacceptable, but would like to pass on to them noise ratings at quiet and full fan speeds. Also as far as I can tell there is no option to run the units without any fan, is that correct?
The Series 2 Lustr units have an option to have the fans controlled via dmx. It is a very quiet fan. The unit will only over-ride that if they units get to hot. A well air conditioned space will help immensely. I do not think that you will notice a significant noise floor increase with only 10 units.
