marcvonstuerler Posted April 5, 2015 Report Posted April 5, 2015 Hello Hello Everybody, Some strange flr flr flr flr flr noise issue with one of my Lectros SMDa. When the Roll-off is on 35Hz it is quasi nothing to hear, i would say ok. But when i go up with the Filter, this Noise go up too. At 150Hz it sounds like a humide Schoeps. This is the same with different Mics, Receivers etc. new Batterys... I have two SMDa, only one have this problem. Somebody have an Idea, or same Experience ? I expected have to send it to Lectros or Ambient... Best Regard, Marc. Quote
Christian Spaeth Posted April 5, 2015 Report Posted April 5, 2015 Doesn't sound like something I've heard on my Lectros. If it's only audible on this transmitter you're right in sending it in. Maybe call Ambient before and ask, but thea will probably tell you to send it in anyways. Quote
Philip Perkins Posted April 5, 2015 Report Posted April 5, 2015 Does your TX do this if no mic is plugged in? Diff mics? On a line source? p Quote
marcvonstuerler Posted April 5, 2015 Author Report Posted April 5, 2015 Thanks Christian and Philip, The Problem is only with plugged Mic. Yes it's still the same with different Mic (DPA, Sanken, VT...). In line in on the Transmitter no problem, the Roll-off Filter is not active on Line input on the SM. Marc Quote
