I have just sold my SGC-2020 ADSP2.  I had it upgraded.  I don't know 
now it will work in the Mark V, but it really cuts out the background 
noise.  I live in a retirement  apartment and it is quite noisy here.

I should have my new 756PRO II next week and I will be interested to 
see how it compares with the SGC.  The noise filter works in two 
stages, it is not continually adjustable. the first one is down 13dB 
and the second is 26dB.  I couldn't believe how well it works.  It 
also has bandwidth filters, 1800 Hz, 500 Hz and 100 Hz.
