gwak ki nam Posted February 21, 2021 Report Share Posted February 21, 2021 I'm using sanken cos-11d I am using a lectrosonics smdwb transmitter Like on the lectrosonics homepage I wired with a 1k resistor I have a question I'm a beginner of a recording engineer so please understand I am curious about why I need to do 1k wiring What's the good thing? And in case of not wiring 1k Tell me about the shortcomings Quote Link to comment Share on other sites More sharing options...
r.paterson Posted February 21, 2021 Report Share Posted February 21, 2021 Without the 1k resistor you get an increase in distortion ..you can wire servo bias for lectro tx without a 1k resistor that wire (white?) goes straight to pin 5 with no resistor, instead of going thru a 1k to pin 1..servo bias is the prefered method if wiring..

LarryF Posted February 22, 2021 Report Share Posted February 22, 2021 At high sound levels, the 1k resistor reduces the distortion from 7% to less than 1%. The resistor provides large quantities of negative feedback which reduces distortion. This also reduces the "gain" of the mic but that is easily compensated for in the transmitter. I highly recommend the 1k (1k to 4k) resistor.

Going to pin 5 substitutes an internal resistor in the transmitter for the 1k, accomplishing the same distortion reduction. It is not universal wiring of course.
