A quick clip from the first 'real' job that I used a 1khz tone generator with the 5dmkII. I fed it into my Sound devices mixer, then into a Beachtek DXA-6. By feeding 1khz into the left channel I was able to completely fix the agc level. I am pleased to report that there was no tone bleed at all using this combination (unlike the DXA-2s).

First few seconds are how it sounds with the left (tone) channel removed so you can hear how it sounds.

Mic is a Sony wireless lapel mic.
