Lexicon Lamda Problem
I have a Sterling st-51 condenser mic and purchased a Behringer xenyx 1002b mixer. Similar problem, dynamic mics work in low impedence with or without phantom pwr on. My Washburn acoustic bass with preamp in line input section. So I tried it on my Omega Lexicon interface. The condenser mic and everything else works on the Omega. This unit has a wall wart ( your Lambda is USB powered). I checked the voltages with a meter and found 23 volts from the mixer and 48 volts from the Omega. Further, I have two Shure SM-82 line mics which work on the mixer with the inputs turned all the way down but do not work on the Omega nor on my Spirit SX mixer which has 48 volts phantom power. The SM-82s are old line mics that have a 9.6 volt battery in the sleeve. They overload badly in all but the 1002B mixer. Their voltage should run btwn the 9.6 battery or a 22 volt phantom power.
Check your Lambda voltage, It could be way less than needed by the st-51. I will check with a friend who has the Lambda and check its voltage. Bet it is too low.
Again, My St-51 and 1002B mixer combo barely works at 23volts, the Mic gain is all the way up as is the channel slider and the main output slider. I cant get any reading on my led meters, occasional bump on the first light, no possible way to clip the input or the output and have to turn the high eq off and the mid way back due to hiss noise. Hope this helps,couldn't find minimum voltages on the ST-51 as yet.
