gabi Posted May 20, 2010 Report Share Posted May 20, 2010 For those mixers using the Lectro 400 series for wireless boom, do you use the Smart Noise Reduction algorithm to reduce the hiss produced by the mic preamp or the mic itself? Or do you keep it off to preserve complete transparency? Thanks in advance, Gabi Cunha. Quote Link to comment Share on other sites More sharing options...

Why is there hiss in the first place? - Jeff Wexler Quote Link to comment Share on other sites More sharing options...
Richard Lightstone, CAS Posted May 20, 2010 Report Share Posted May 20, 2010 Jeff, Here is Lectrosonics description of what it is: SmartNR™ With a noise floor at -120 dBV and a frequency response to 20 kHz, high frequency noise in the source audio is more apparent than in conventional wireless systems. The Smart Noise Reduction algorithm works by attenuating only those portions of the audio signal that fit a statistical profile for randomness or “electronic hiss.†Because it isn’t simply a sophisticated variable low pass filter as in earlier analog designs, much greater transparency is obtained. Desired high frequency signals having some coherence such as speech sibilance and tones are not affected. The Smart NR algorithm has three modes, selectable from the front panel LCD. When switched OFF, no noise reduction is performed. When switched to NORMAL, the factory default setting, enough noise reduction is applied to remove most of the hiss from the mic preamp and some of the hiss from lavaliere microphones. When switched to FULL, enough noise reduction is applied to remove most of the hiss from nearly any signal source of reasonable quality, assuming levels are set correctly at the transmitter. Gabi, I do not use the so called "Smart NR" feature on the Lectrosonic receivers - meaning I leave it "Off". Quote Link to comment Share on other sites More sharing options...
studiomprd Posted May 21, 2010 Report Share Posted May 21, 2010 you could try it out and see what setting sounds the best for your situations, in fact perhaps you should try it... I typically use 'normal', and no one has ever said anything to me about any issues...no one! ever!! Quote Link to comment Share on other sites More sharing options...

hemmerlinj Posted May 22, 2010 Report Share Posted May 22, 2010 I think normal is where it is set on the lectros right out of the factory. Quote Link to comment Share on other sites More sharing options...
Mark LeBlanc Posted May 22, 2010 Report Share Posted May 22, 2010 Just got a new SR three days ago, NOR is the factory default. On a windy day like yesterday I had it on NOR, will turn it off for INT.. Quote Link to comment Share on other sites More sharing options...
