TKinney Posted September 17, 2015 Report Share Posted September 17, 2015 Do the new Lectrosonics LMb Transmitters have the same power output as the previous discontinued LMa Transmitters? There has been discussion that the older LMa were rated at 50mw but have a power output closer to 70mw. Maybe Larry Fisher can chime in on this one. Do they have the same power unit? or completely different, Thanks, in advance Ted Kinney / Soundman Portland, OR Quote Link to comment Share on other sites More sharing options...
bmfsnd Posted September 18, 2015 Report Share Posted September 18, 2015 Hi Ted, The LMb is essentially a 3-block LMa with other features seen in the L-Series. It has a max Tx output of 50 mW. It's powered by two AA batteries. You can find more info about the L-Series in my in-depth testing & review here. Quote Link to comment Share on other sites More sharing options...
karlw Posted September 23, 2015 Report Share Posted September 23, 2015 Ted, It's true that earlier LM and LMa transmitters were not often as tight with the RF power as some of our other units (like UM400a for instance) so yes, they might have as much as 70 mW although most were closer to 50. The LMb does have a very different output stage from the LMa, and in general will be closer to 50 mW in most samples. All that said, the difference of 50 mW to 100 mW is only 3dB, so 50 to 70 is maybe 1.5 dB - hardly noticeable in field use. The variations in reception due to other factors are far greater.
